Ian Pace : What is the basis upon which you choose the particular
configurations of instruments you employ?
Gordon Downie : As I have already indicated, negation is one of the primary formal tools structuring my music. The choice of instruments is
governed by this principle. Thus, the instrumental configurations
that I use emphasise maximal timbral differentiation. This
becomes more apparent in the larger works such as forms 5:
event intersection and forms 6: event aggregates , where all
instrumental families are represented. Within particular works,
sub-ensembles also function as attributes or features of event types,
which are also characterised by gestural profile, duration,
tempo, and impulse-density, for example. Instrumental
configuration is in this instance part of a wider organisational
principle, functioning to control the progression of colour contrast
and volume, and various levels of density and activity throughout
the work. forms 3: equivalent forms , for example, is
constructed from seven event-types and each is characterised by
seven configurations of one, three, five, seven, nine, eleven, and
thirteen instruments. Such organisational techniques are
particularly effective projected within very large forces, as
opportunities are created for superimposing such processes in
very diverse and complex ways. forms 6: event
aggregates begins this process which forms 7 will extend much
further.
IP : forms 3: equivalent forms for 13 players in particular
seems to present a highly 'egalitarian' relationship between the
different instrumentalists. Do you see any sort of innate
hierarchies between instruments, and if so is this something you
try to counteract? Would you consider writing a work for soloist
and ensemble?
GD : The suffix to forms 3: equivalent forms points to one of
the main concerns of both this particular work and my practice in
general. Though equivalence is a notion central to integral
serialism, it is also a dominant conceptual tenet of many of the
most significant movements in 20th century visual art and
architecture, such as De Stijl; and Stockhausen's concept of
mediation is essentially equivalence with another name, though
more formally conceptualised. Equivalence posits the rejection of
hierarchical structuring in favour of heterarchical structuring. In a
heterarchical structure, all components are assigned equivalent
status. This formal concern penetrates the organisation of forms
3: equivalent forms at every level, and accounts for the
'egalitarian' relationships that I attempt to establish in the
distribution of the thirteen instruments. But this can only be
achieved by demoting the primacy of pitch in order that
percussion instruments such as temple blocks, wood blocks, and
tom toms, can compete more equally with other members of the
ensemble, in order to mediate between pitch and noise, or
between the fully discrete and the continuous. This is achieved by
employing pitch structures that exhibit a high level of invariance.
There is little change or differentiation within this parameter
throughout the work, which is formed almost exclusively from a
single pitch class set, namely 3-3 using Forte's terminology.
Through this form of cognitive saturation, listeners' attention is
inevitably drawn to other parameters that are customarily
subordinated or suppressed. This creates opportunities for
instruments that are pitch-impoverished to contribute more
equally to the musical argument.
But other factors contribute to this process of pitch-demotion.
The use of more or less densely articulated textures of sound,
which are frequently opaque in quality, hinder the perception and
definition of clearly delineated and precise pitch content. This is
achieved by the use of either forward or backward temporal
masking, whereby successive impulses mask or interfere with one
another. This problematizes pitch definition. But with successful
masking intervals being smaller than or equal to fifty
milliseconds, we can only notate such effects indirectly and
indeterminately, by superimposing different strata of mutually
negating activity, the emergent complexity of which is a sum of
that process of superimposition. This is how Stockhausen
achieved some of the most effective, amorphous complexes
in Gruppen , and it's a technique which contributes to the
effectiveness of Gilbert Amy's use of two nearly identical
ensembles in his Diaphonies : such effects are even more
successful applied to identical timbre. In addition, forms 3:
equivalent forms, tends toward using fewer long durations, a form of
articulation not generally available to percussion instruments. As
the discriminability of the frequency of pitches is reduced the
shorter in duration they are, this feature contributes to the
successful mediation of pitch and noise. Psycho-acoustics offers
us a wealth of analytical and generative tools with which to
explore these new sonic phenomena.
But as I outlined earlier, processes of parametric foregrounding
cannot occur in isolation: one must consider how changes in one
parameter propagate and affect others, or consider that in
affecting change in one, others may need similar levels of
processing. Thus pitch-demotion is itself a multiparametric
operation. If this is not taken into account, one will
achieve the kind of nonsense that often passes for radical action:
notating key-slaps or various forms of ad hoc distortion for
woodwind and brass in the hope that pitch and noise can be
successfully mediated (assuming the composer in question even
realises this is what they are trying to do) only emphasises even
more their oppositional characters. You are right to query
whether my concern for structural equivalence could be
consistent with the demands for hierarchy that inhere in soloistic
or concerto forms. Clearly they would not, and it is for this reason
that I have not so far explored this area. But I have often
contemplated how it might be done, and several methods await
further elaboration. These include the use of multiple soloists
employing multiple timbres, or, perhaps more effectively,
multiple soloists employing singular timbre, such as five harp
soloists with ensemble. In a sense, one has to find a way to
project a one-to-many form within a many-to-many conceptual
framework.

Zita Fabbri: Can you elaborate upon the compositional techniques and structuring methods used in forms 3: equivalent forms?
Gordon Downie: piano piece 1 and forms 3: equivalent forms employ similar methods. They were, of course, composed within a few years of each other. In considering their inter-connectivity, we need to consider what techniques were used to, as I stated earlier, maintain “high levels of similarity, invariance, or equivalence between structural and behavioural components, whilst simultaneously projecting them in ways that generate significant levels of differentiation and cognitive stimulation and sensation”. Within the context of pitch organisation, my interest was to construct a work using an interval organisation exhibiting a very high level of invariance and concomitant redundancy whilst extracting maximal differentiation within the imposed constraints using limited operations. Imposing high levels of invariance, or low levels of change and/or variability within one parameter, is one means by which higher levels of equivalence can be achieved between parameters. I outlined this approach in response to Ian Pace. In both works a single source trichord – (0, 1, 4) or 3-3 in Forte’s notation – and its’ transposed retrograde inversion is formed and combined to generate the source hexachord. The process of generating a retrograded and transposed form of this hexachord at interval class 6 furnishes the second hexachord to complete the aggregate.
The operations of rotation, permutation, and hexachordal combinatoriality are then applied to the source series. Given the nature of this serial complex, there is already a high level of inbuilt internal similarity, correspondence, and equivalence between set components. The application of secondary operations such as rotation and permutation and methods of set intersection employing hexachordal combinatoriality, functions to maintain this high level of structural cohesion and identity with the underlying, original intervallic structure, whilst adding limited and controlled levels of differentiation. The rotation operator, for example, represents - after the standard operations of retrogradation and inversion - the most extensive transformation possible whilst maintaining the fundamental structural identity of the operand, here the series. This level of extreme cohesion is similarly applied to all other structural parameters, such as temporal and spatial assignments, impulse density, and so forth. I should stress that these concerns are represented in all my work from a variety of perspectives. Perhaps the focus here involves an attempt to retrain the user - the auditor - to respond to higher and finer levels of behavioural gradation. One might imagine that, if this process of retraining or reconditioning was successful, the levels of change and contrast customarily exhibited by music would be deemed incoherent and unintelligible, indeed intolerable.
The structural constraints and organisation outlined here define sets of behaviours. Their reiteration creates predictive spaces that tightly control levels of cognitive stimulation, arousal, and expectation. Predictive spaces correspond to temporal windows within which events and behaviours occur, and define a duration, a time period within which certain behavioural constraints are operational. And such spaces are defined, in part, by those processes of desensitization that result from over-exposure and saturation to classes of stimuli. By closely determining the location and extent of behaviours that deviate from expectations generated by the predictive spaces, the precise temporal definition of such spaces can be complexly mediated. In consequence, cognitive stimulation is maintained, in part, by the extension and contraction of the time elapsing between the presentation of stimuli that do not conform to or frustrate expectations.
The levels of difference exhibited by stimuli can be organised to operate within the subliminal to the supraliminal. Subliminal stimuli or processes are those to which the subject does not consciously attend, whilst supraliminal stimuli or processes are those about which the subject has more or less full awareness. Within each category are located objects, events, and processes. In this context, a subliminal stimulus is an object, event, or process that, whilst an essential element in the overall behavioural profile of the percept, is one that is subordinated or masked by, supraliminal stimuli the configuration of which require more immediate or urgent attention and/or processing. However, whilst subordinate, research indicates the extent to which such stimuli, nevertheless, make information processing demands, affecting processes of cognition and perception.
This is a potentially powerful means by which to maintain stimulation, cognitive engagement, and arousal in contexts where the primary concern is extreme structural homogeneity and cohesion that strongly delimits the range of available and permitted behaviours and stimulants. Unlike the subliminal, whereby change is articulated at thresholds located below conscious perception, in the case of supraliminal stimuli, the levels of difference exhibited can be calibrated to mediate between stimuli exhibiting minimum differentiation, such as perceptual distinctions generated by a just noticeable difference metric, to maximum differentiation, however that might be defined. Subjected to permutation, such a range generates controlled levels of uncertainty, one of the primary mechanisms for generating forms of cognitive arousal and stimulation. Applied to a specific parameter, such as duration, subliminal stimuli are categorised here as sets of events or objects for which metrics are defined in milliseconds that, whilst resisting explicit differentiation, are nevertheless non-uniform. This can be applied to individual impulses or events. Applied to the former, duration classes define membership in terms of distance from a centroid calculated in milliseconds. In the following example illustrating a duration class comprising a collection of tuples, using 60 impulses per minute and the eighth note as the temporal reference, the centroid is defined as 70 msec and distance as any value ± 30 msec. This level of differentiation becomes more acutely effective operationally over the longer term in which the sample space is of a sufficient duration for these features to be established.
