2. Background

The concepts of maximal and minimal voice are borrowed from the literary theorists Donald Wesling and Tadeusz Slawek and their use of these concepts in the book Literary Voice: The Calling of Jonah (Wesling and Slawek Reference Wesling and Slawek1995). The two concepts are presented as ends or extremes of literary voice, and these are theorised by the authors by analysing texts that are seen as belonging to each of the extreme positions. Although literary voice is a more abstract notion compared to audible voice, fundamentally bound up in the often highly problematic relationship between speech and writing, there are several issues addressed by these authors that appear to be relevant also for loudspeaker mediated voices, like meaningfulness, intelligibility, presence, the relationship between voice and person, expressivity, intentionality, individuality and bounding outline. Many of these issues can be recognised in the seven premises of the max–min model, even if they have had to be greatly adapted and re-worked.

In addition to Wesling and Slawek, two radio theorists have presented ideas that have had an importance for the development of the model. Firstly, Bodil Børset, also drawing upon Wesling and Slawek, has analysed Nathalie Sarraute's pièces radiophoniques, focusing on aspects such as the strength of the link between character and voice, the degree of separation between a voice and background noise, voice familiarity, intelligibility, the ‘materiality of sound’, and the dissolution of sense and meaning (Børset Reference Børset2006: 128–31). Here the first four aspects were discussed as factors pulling the voice towards the maximal, whereas the latter two were seen as drawing it towards the minimal. Secondly, what Frances Dyson has written about radio voice corresponds in many ways to the ideas of Wesling and Slawek. In her article ‘The Genealogy of the Radio Voice’, she mainly focuses on what she calls the ‘dominant’ radio voice (Dyson Reference Dyson1994). This type of voice has many parallels with the literary maximal voice, even if it doesn't explicitly relate it to the idea of a continuum and the existence of an opposite pole. She writes that ‘[generally], the dominant radio voice talks – its speech is clear, articulate, sometimes eloquent. Most of what it says is perceived by the listener as factual and informative … It does not mumble or stutter, it pronounces full and meaningful sentences, it says something’ (1994: 167). Presence is also an important aspect of Dyson's notion of the dominant radio voice: ‘For the voice being sonorous, necessarily speaks in the present, is accompanied by the actual bodily presence of the speaker, and is heard (perceived) at the moment of its production’ (1994: 176). Furthermore, she states that a voice also has to be singular – in other words, it must appear one at a time, and it has to appear as the only audible sound source, or alternatively as the foreground phenomenon with very few other sound sources interfering, to aspire to the dominant radio voice (1994: 181–2). Despite the fact that Dyson mainly defines the dominant radio voice positively, she also demonstrates ways in which some aspects can be negated, and thereby it is possible to relate these negations to the minimal voice. For instance, she sees both bodily ‘noise’ – for example trembling voices, throat clearing, coughing, sneezing, panting – as well as noise from the technology of mediation as factors that undermine the dominant radio voice. Taken together, Børset's and Dyson's writings present several issues that are highly relevant for voices in electroacoustic music, and therefore many of them are adapted to and incorporated in the framework; that is, in the seven premises that I will present below.

The max–min model also draws on theories of electroacoustic music, both more general theories and ones specific to voice. As for the former, I have been influenced by Smalley's theory of transformation, and in particular his idea of source-bonded transformations as relying on an extrinsic identity – in other words, a mental image of a general or specific sound source or action that exists outside of the work (Smalley Reference Smalley1993: 280–1). More specifically, the way he conceives of transformational distance as a ‘subjective measure of degree of change of identity relative to the base identity’ (1993: 287) has been particularly influential. This parallels how I regard the experience of the (often transformed) voices in electroacoustic music as subjectively defined through the relationship to the (untransformed) maximal voice, and how this interrelationship can be expressed and visualised spatially – as located on a continuum closer or further from the maximal voice. I will return to the details of this below.

Furthermore, the maximal–minimal model also draws upon Emmerson's notion of physical presence, which deals with listeners’ reconstruction of physical action and agencies, including all types of (living) sound sources and actions, and their disposition in and interaction with an environment (Emmerson Reference Emmerson2007: 18–23). Finally, I am also relying on theoretical models that have described the continuum between the concrete and reference oriented on one side, and the abstract and sound-quality oriented on the other side (Chion Reference Chion1988; Emmerson Reference Emmerson1986; ten Hoopen Reference ten Hoopen1992; Young Reference Young1996).Footnote ²

The theories that are specific for voice in electroacoustic music are naturally even more interesting. In Bruno Bossis's groundbreaking book La voix et la machine he introduces the concept of artificial vocality, a term that in its turn conjoins the concepts of ‘vocality’ and ‘artificiality’, in principle covering all aspects of vocal or vocal-like expressions in sound mediated by loudspeakers, but in practice focusing on voice in electroacoustic works (Bossis Reference Bossis2005). By using the term ‘vocality’ rather than speaking of the voice, Bossis opens up for seeing the phenomenon as a graded quality rather than a question of either–or. In summing up the ideas presented in the book, Bossis emphasises how artificial vocality is played out in a generalised continuum, where all musical parameters are continuous (2005: 288). More specifically, he draws up a continuum between the ‘frankly vocal’ (‘franchement vocal’) and what is ‘not at all vocal’ (‘pas du tout vocal’) (2005: 288). What is more, he argues that the detachment of the voice from bodily production, which characterises artificial vocality, delineates a continuum between the human and the synthetic (2005: 289). All in all, the idea of the continuum is a very important one in Bossis's discussion of artificial vocality, and it is not difficult to see the similarity between these ideas and the gradation between the maximal and the minimal fulfilment of the naturalness premise.

A much less developed theory, but still interesting in this context, is presented by Segnini and Ruviaro in their paper ‘Analysis of Electroacoustic Works with Music and Language Intersections’ (Segnini and Ruviaro Reference Segnini and Ruviaro2005). Here, the authors break down the analysis into two dimensions in what they call a ‘music-language sonic space’, where ‘musicness <–> speechness’ constitutes one axis and ‘unintelligible text <–> intelligible text’ the other. These dimensions resemble certain of the premises of the model I will present below, and their use of a spatial model with two continuous dimensions parallels the way the premises can be treated as dimensions, as will be clear from the forthcoming discussion.Footnote ³

There are also two other theoretic fields that in themselves are perhaps not related to Wesling and Slawek's ideas of literary voice, but that I still have found relevant for my framework, namely cognitive load theory (Halford, Wilson and Phillips 1998; Paas, Renkl and Sweller 2004) and other related theories of information and redundancy (Eco Reference Eco1989), as well as auditory scene analysis theory (Bregman Reference Bregman1990). Again, it would be outside the scope of this article to deal with these theoretic fields here, and readers should consult chapters 6 and 12 of my thesis (Bergsland Reference Bergsland2010) for details.

3. Maximal voice as a set of premises

Retaining many of the ideas presented above, I will now formulate the maximal voice as a set of premises. The premises each express one particular aspect or feature of the maximal voice, similar to several of the aspects mentioned in the discussion above. Each of these premises can be seen as conditions that can be fulfilled to different degrees, and when they are all fulfilled, the result is what I define as maximal voice. Since fulfilment is graded, the premises can be seen as continua running from the maximal to the minimal, in line with the idea of a graded continuum that we could find both with Wesling and Slawek and with many of the electroacoustic theoreticians. And they can be taken as the basis for an evaluation that can be represented graphically along a set of axes, as I will show in section 6 below.

It is possible to conceive of several ways in which the main ideas presented above could be organised into premises, for instance regarding their number, what ideas they comprise and what they are called. And, indeed, I have operated with several set of premises during the work with the model (see Bergsland Reference Bergsland2006). Hence, the seven premises that I present here are not ‘written in stone’ but constitute what I have found to be the clearest and most useful organisation that allows for sufficient distinction and a good balance between overview and detail. Here, I present them together with a set of associated keywords that links them to the theoreticians and theoretical groundings that I discussed in the previous section:

1. 1. Focus of attention: The semantic issues of any verbal structures receive sustained and maximal attention. (See sound materiality (Børset Reference Børset2006); reality–abstraction continuum (Young Reference Young1996); musicness–speechness (Segnini and Ruviaro Reference Segnini and Ruviaro2005).)

2. 2. Information density: Information density is optimal for the processing or decoding of the verbal structures. (See cognitive load theory (Halford et al. Reference Halford, Wilson and Phillips1998; Paas et al. Reference Paas, Renkl and Sweller2004); information, redundancy (Eco Reference Eco1989).)

3. 3. Naturalness: The sound has maximal resemblance with one produced by a human being and his or her vocal apparatus. (See artificial vocality (Bossis Reference Bossis2005).)

4. 4. Presence: The listener experiences a sense of a shared ‘here and now’ with a vocal persona. (See presence (Dyson Reference Dyson1994; Wesling and Slawek Reference Wesling and Slawek1995; Emmerson Reference Emmerson2007).)

5. 5. Clarity in meaning formation: Meaning can be constructed from the voice with a high degree of clarity – also implying specificity, certainty and coherence. (See intelligibility, meaningfulness (Wesling and Slawek Reference Wesling and Slawek1995); intelligibility, voice familiarity, dissolution of sense and meaning (Børset Reference Børset2006); clear speech, articulate, factual, informative, full and meaningful sentences (Dyson Reference Dyson1994); intelligible text (Segnini and Ruviaro Reference Segnini and Ruviaro2005).)

6. 6. Feature salience: Vocal sounds and features ‘stand out’ perceptually – for themselves and relative to other sounds and features. (See individuality and bounding outline (Wesling and Slawek Reference Wesling and Slawek1995); separation between a voice and background noise (Børset Reference Børset2006); singularity, foreground phenomenon (Dyson Reference Dyson1994).)

7. 7. Stream integration: The sound of the voice is integrated into one coherent and continuous sound stream. (See auditory scene analysis (Bregman Reference Bregman1990).)

In my thesis, these seven premises are individually given a theoretical grounding and related to a set of factors, which affect the evaluation of each of them. This provides the basis for detailed criteria for evaluation of each premise along the max–min continuum, where the importance of the listeners’ background, knowledge and experience as well as the listening conditions (e.g. how many times a piece is listened to, or if it is listened to in one stretch or paused) is emphasised. These criteria are then applied in an evaluation of selected excerpts of music. Moreover, I show in my thesis how several of the premises are partly interconnected in that a premise can constitute a factor affecting the evaluation of another premise.

While the details of each premise and its use in evaluation have to be left out in this context, I will instead focus on more general issues. If we start with maximal voice, it is not encountered in its fullest sense too often in the type of material that I have focused on in my work, but tends to be the rule in other sonic expressions as radio and audio-book genres such as the interview, speeches and lectures. One example from electroacoustic music that approaches maximal voice can be found in Les objets obscures (1991, on Parmerud Reference Parmerud1994) by Åke Parmerud. In this piece, a French female speaking voice is heard at several salient points in the piece. Several times this voice appears on its own, close and without any reverberation, devoid of ambient noise, speaking in an articulate and fluent manner, clearly intelligible, at least for listeners who understand French. Yet on the semantic level there is not so much clarity: the sentences are not always complete, and what is referred to remains mostly rather obscure since the woman is presenting a riddle, a riddle which hints at the ‘hidden objects’ that can be heard in the piece, and that the title refers to:

Even if the answers to the riddles are presented in the fourth part of the piece, the general impression is that this is quite far from the meaningfulness of the informative and factual radio voice. Moreover, the voice is only present in short sections at a time, sections which function mostly as introductions to the more ‘musical’ parts of the piece. This woman is therefore felt to retreat to an undefined absence during most of the piece, thus being only temporarily present for the listener. One can see that even if this voice doesn't bear all of the characteristics described above, it still seem to largely fulfil many of the premises such as focus of attention (at least for those understanding French), information density, naturalness, presence, salience and stream integration.

4. Centre and periphery

When the experienced voices only partly fulfil the premises of the model, they will depart from the maximal, and at some point of negative fulfilment, in what we might call a violation of the premises, they will ultimately reach a state where they can be characterised as minimal.

The minimal voice is much more difficult to define than the maximal voice because it comprises a wider range of possibilities and modes of expression. For the mentioned seven premises, there are simply more ways in which they can be violated than be fulfilled. Thus, it seems that the relationship between the maximal and the minimal can be described through the dichotomy narrow–broad. For the clarity of meaning formation premise, for instance, the maximal voice will be confined by conventions of speech and language. The minimal voice, on the other hand, isn't confined by any mode of voice at all – it can comprise speech, singing and vocal experimentation. For example, in Western classical bel canto song, which often has a basis in a meaningful text, the text is often unintelligible due to melismatic passages and phrases in high registers that make pronunciation difficult.Footnote ⁴ In artistic vocal expressions of the avant-garde, within as well as outside of music, there are many examples of other kinds of voices that in different ways have presented voice with little clarity of meaning, for example by using non-sense phonetic texts or pseudo-language (as in Ursonata by Schwitters (1922–32, on Schwitters Reference Schwitters1992) or Nouvelles aventures by Ligeti (1962–65, on Ligeti Reference Ligeti2006)). And, clearly, in electroacoustic works one can find a great many examples of types of electronic processing that might affect the clarity of meaning negatively: for example, filtering, time stretching and compressing, granulation and distortion.

In addition to representing one of two extremes in my framework, the minimal voice also represents the possibility of transgressions into what is not voice – it represents a boundary zone where the voice appears to be on the verge of turning into what is no longer a vocal sound. And, in electroacoustic music the boundary between what is voice and what is not voice is the subject of exploration in several works, among them Stockhausen's Gesang der Jünglinge (1956, on Stockhausen Reference Stockhausen2001), Wishart's Red Bird (1977, on Wishart Reference Wishart1992), Mortuos Plango, Vivos Voco by Jonathan Harvey (1980, on Various Artists 1990) and Chant d'ailleurs by Alejandro Viñao (1992, on Viñao 1994). In these and several other pieces one can experience gradual transformations between vocal sounds and sounds that are clearly of a different origin.Footnote ⁵ In the very beginning of the latter work (0′00′′–0′30′′), for instance, there is a sustained note which transforms gradually and continuously from a wind instrument with a rather ethnic and Eastern flavour into a singing voice. This happens rather slowly and in several stages, and at one point (I experience this around 0′20′′) the sound begins to take on the qualities of a voice. At this point, however, it is still lacking greatly in naturalness compared to a real voice due to the fact that it lacks the small irregular fluctuations in pitch and amplitude that are characteristic of the human voice.Footnote ⁶ When the pitch fluctuations set in a little later, however, the sound becomes more natural, until it finally sounds just like a sung note. One can thereby experience that the sound gradually changes from non-voice into voice, and that, at one point, the sound passes through a boundary zone between the two. I will return to a more in-depth discussion of such boundary transgressions below.

One useful way of visualising the discussed relationships between the maximal and the minimal voice is a circular centre–periphery model (see Figure 1). Here, the maximal voice constitutes the centre and the minimal voice the periphery, which borders onto what is not voice.Footnote ⁷ Moreover, in this model the maximal voice is clearly more narrowly defined than the minimal, representing the multitude of ways that voice can depart into the minimal and ultimately into non-voice. The idea of a graded continuum between the maximal and the minimal is also retained in this model. Still, the model lacks the connection to the seven premises introduced above, and I will therefore look into ways of expanding it. Theories on categorisation and prototypes appear to offer such a link, and consequently I will look into these theories in the following section.

Figure 1 Centre–periphery model of maximal and minimal voice.

5. Parallels with categorisation models

Eleanor Rosch's and George Lakoff's writings on categorisation and prototype theory present ideas that pose some interesting links to the framework I have hitherto delineated. I will argue in the following that my model in many ways is structured like a particular type of category described by Lakoff, where the category in my specific case will be ‘experienced voice in electroacoustic music’.

Prototype theory was formulated by Eleanor Rosch in the 1970s, but has several predecessors, within philosophy, cognitive anthropology and social psychology (Rosch Reference Rosch1975; Rosch and Mervis Reference Rosch and Mervis1975; Rosch Reference Rosch1978).Footnote ⁸ Her theory was formulated in opposition to the ‘classical’ view of categories, which saw them as rooted in the objective structures in the physical world. Within the classical view of categories, certain members of a category could not be seen as more central or typical to the category than others, since the categories in themselves would be determined by shared properties rooted in an external and objectively given world, thus endowing all members of a category equal status. However, through reviewing a series of earlier empirical studies and undertaking a set of new ones, Rosch was able to find what she called ‘prototype effects’; in other words, that some members of a category were taken to be more prototypical or better examples of the category than others. For example, she found that some species of birds were thought of as better examples of the category ‘bird’ than others; whereas robins and sparrows were considered the best examples, owls and eagles were not so good examples, and penguins, emus and ostriches were considered worst examples of the category (Rosch Reference Rosch1975).Footnote ⁹

If we go a bit further into the claims of prototype theory and related theories, we can see that the relationship between the typical and the less typical members also resembles the relationship between maximal and minimal voice, if we regard the whole continuum between the poles as constituting the category ‘experienced voice in electroacoustic music’. In the same way as minimal voice is defined in relation to maximal voice, in prototype theory non-prototypical members of a category are defined in relation to the prototypical. In the words of Lakoff and Johnson, ‘[we] understand the nonprototypical chairs as being chairs, not just on their own terms, but by virtue of their relation to a prototypical chair’ (Lakoff and Johnson Reference Lakoff and Johnson1980: 122, my italics). If we return to the premises that define the maximal voice, we can see that they at the same time define what the minimal voice is not. Thus, anything that would be considered as minimal voice would be, in a similar manner as in prototype theory, defined in relation to the maximal voice. In this respect, my model seems to fit the structure of categories in prototype theory.

Moreover, one can see that the spatial metaphor that is implied for the prototypical categories, with some members that are more central than others, in many ways resemble my model, in that they both can be thought of as graded continua between centre (the prototypical members) and periphery (the worst examples). This is evident from Lakoff's summary of the basic results of prototype theory: ‘Some categories, like tall, man or red, are graded, they have inherent degrees of membership, fuzzy boundaries, and central members whose degree of membership (on a scale from zero to one) is one … Other categories, like bird, have clear boundaries; but within those boundaries there are graded prototype effects – some category members are better examples of the category than others’ (Lakoff Reference Lakoff1987: 56). Without addressing the question of the different kinds of boundaries mentioned here at this point, we see that in both cases there is a question of graded prototype effects.

As we saw above, I listed several constituent premises that together converged to define the maximal voice of my model. This resembles what Lakoff calls cluster models, which designate a source of prototype effects in his theory. Cluster models involve several cognitive models, which for Lakoff are mental constructs involved in the organisation and structuring of knowledge and meaning: for example, in forming categories (Lakoff Reference Lakoff1987: 74). These cognitive models will in some cases cluster together or converge to form categories that are psychologically more basic than the models taken individually, hence the term cluster models. When all the cognitive models in a cluster converge, it will then result in a more central or prototypical category member than when there are only just a few models clustering or no clustering at all, something which will result in more peripheral members.

Hence, we can see that this way of thinking about categories appears to have many similarities with the way in which the maximal–minimal framework was structured; the maximal voice was defined according to a set of premises, in many ways resembling the cognitive models of Lakoff; the minimal voice was defined in relationship to the maximal; and the maximal was seen as more central than the minimal.Footnote ¹⁰ One difference, however, is that, whereas the subcategories in Lakoff's case were restricted to established, conventionalised categories, my model is in principle open to all kinds of combinations of fulfilment or violation of the premises.

This resemblance with Lakoff's structuring into cluster models seems to reinforce the spatial representation in a circular centre-periphery earlier shown in Figure 1. What is more interesting is that it seems to open up for an inclusion of the premises of the model into this picture, since the premises are seen as converging in the centre and diverging towards the periphery. When also taking into account that the premises can be regarded as graded continua running from the centre to the periphery, the spatial representation of the premises as kinds of dimensions having axes pointing outwards from the centre, almost suggests itself. Consequently, an expanded version of the centre-periphery model would be something like Figure 2.Footnote ¹¹

Figure 2 Extended centre–periphery representation of the maximal–minimal framework. The seven axes represent the seven premises introduced in section 3 of the article.

However, I want to emphasise that despite the similarity with mathematical representations of an n-dimensional space, the axes in this case are not ‘true’ dimensions in the sense of being orthogonal or independent of each other.Footnote ¹² Rather, I think of this representation as a system of axes in the sense proposed by Godøy (Reference Godøy1997). Godøy regards the notion of axes as applicable in principle to anything that can be regarded as an aspect of music, and axes are seen as having both a hermeneutical role as a visualisation and understanding of an aspect, and a role in generation or simulation (1997: 186–7). While the latter is not an issue in this context, Godøy's view of the generality of axial representation in representing aspects along a continuum seems to fit perfectly with my model, and his emphasis on the hermeneutical role that allows for understanding and visualisation is also very much in line with my intention of using such a representation.Footnote ¹³

While formalisations as the one proposed here always risk simplifying matters and falling short of representing the singularities of individual pieces and listenings, there are also important benefits. Perhaps the most important point of these axes is that they allow for comparisons, both between two or more different segments of music and between single segments and hypothetical values along an axis: it is by seeing musical segments, both actual and hypothetical ones in relation to one another, that the possibility of knowledge and understanding lies, according to Godøy (Reference Godøy1997: 190). Thus, by assigning a segment of music to a value along one axis, one has the possibility of seeing this segment in relation to the other values on the continuum, for instance the maximum or the minimum, as well as the possibility of seeing it in relation to another segment of music evaluated with a value along the same axis. Hence, axes in Godøy's sense are tools for relational thought, rather than an absolute mapping of exact values where the assignment of a value along an axis for a musical segment constitutes an act of relative comparison. This value might be graded in different resolutions, from coarse (high–medium–low) to fine (1–20), depending on the possibilities for differentiation along an axis (1997: 146). I largely apply a relatively coarse resolution with the continuum divided into five categories, of which two are the maximal and the minimal poles, one is at the intermediate position, and the remaining two are between the intermediate and the maximal and minimal poles (see Figure 3). In principle, however, one can choose other resolutions depending on the degree to which it is possible to make distinctions and comparisons.

Figure 3 Five value categories along the maximal–minimal continuum.

6. Analytical applications

The maximal–minimal model, supported by the experiential domains framework mentioned in the introduction, can also be applied analytically dealing with concrete works of music. The criteria mentioned in section 3 provide a way of evaluating phrases from particular pieces according to all the seven premises (Bergsland Reference Bergsland2010: chapters 5–11), and the result of such an evaluation can then be visualised in two ways – namely, axial and time-varying representations – which I will demonstrate in the following two sub-sections.Footnote ¹⁴ In this article, I will explain these types of representations using the first 27 seconds of the third movement of Paul Lansky's Six Fantasies on a Poem by Thomas Campion entitled her reflection as an example (Lansky 1979, on Lansky Reference Lansky1994).Footnote ¹⁵

6.1. Axial representations

In Figure 4, I have shown the two types of representation along with a traditional spectrogram and a segmentation of the different phrases, the latter shown as rounded rectangles with text grouped into four different phrase categories (a, b, c, d) based on a similarity/difference evaluation, all made with the use of the Acousmographe software.Footnote ¹⁶ If we start to take a look at the axial representations, they are located in the chain of white rectangles at the top of the graphical panels. We can see here that the shapes are based on the extended centre–periphery representation with the seven axes presented in Figure 2 loosely combined with the five value categories presented in Figure 3. In all representations, the fuzzy circular grey area in the centre represents the zone of the maximal voice, and the peripheral fuzzy circular grey zone represents the zone of the minimal voice. These areas are drawn rather fuzzy or diffuse to underline the lack of any precisely defined limit for these evaluations. The evaluation of each of the premises at one particular time, indicated by a vertical grey line, is then represented by points on each of the seven axes. By defining a line between each of the points and an area enclosed within this line, one will have a representation which shows the evaluation for all the different premises together, especially since the shape and the size of the area give a lot of information just at one glance. For example, in cases where the area approaches a circular shape with the crossing of the axes at the centre, one will have evaluations which are relatively similar for all of the premises. Conversely, if the area constitutes a shape with many edges and irregularities, this indicates that the evaluations are more dissimilar, thus covering a greater span between the minimal and the maximal. As for the size of the area, it generally gives some indication of the overall tendency of the evaluation. A maximal voice, for example, will be represented as only a small shape in the centre of the figure, whereas a voice which is minimal for many of the premises will have a much larger area covered. However, since the size of the area bounded by the line between the points also depends on the arrangement of the axes, one cannot use size very precisely as an indicator of overall tendency. The area will for example be much larger if there are evaluations towards the minimal for several axes next to each other than if every other evaluation is minimal and then maximal, the latter giving a more edgy shape with a much smaller area. Therefore, size can be reliable only when the shapes are relatively similar, and this is most straightforward with shapes approaching a circular shape having the meeting point of the axes at the centre. Nevertheless, shape and size together can still be useful in discovering similarities in the evaluation of different phrases, since graphical shapes are very easy and fast to compare visually. Hence, there are both strengths and weaknesses with this form of representation, where the arbitrariness of the placement and order of the axes is perhaps the clearest weakness, and the ‘frozen’ snapshot it creates can be seen both as strength and weakness.

The upper section of each panel shows the axial representations at 13 different temporal locations, while the section just below it shows the time-varying representations of each of the premises in the maximal–minimal model (nomenclature on the left side of figure 4a). The rounded rectangles in the central part of the panels present the text and grouping of each of the phrases in the excerpt.
