The Grille Fonctionnelle, or the Function Matrix, is a selection of categories and symbols that can be used to describe the purpose of a single unit within an electroacoustic composition and its relation to other units. It was created by Stéphane Roy and appeared within his book L'analyse des musiques életroacoustiques : Modèles et propositions, published in 2003. Roy states that the functions are used to "conceptualise role of musical units within a work" defined from the analysis of the neutral level (Roy 2003: 340).

Grille Fonctionnelle framework

The Grille Fonctionnelle is split into five main categories of functions: orientation, stratification, processes, rhetoric of relation and rhetoric of rupture. This categories will be described below.

Orientation

The functions within the orientation category aim to describe the "discursive" musical relation between segmented units within a piece (Roy 2003): 344). Within the category of orientation there are: introduction, trigger, interruption, conclusion, suspension, transition, originator and extension.

Stratification

The functions within the stratification category are used to define the relations of "simultaneity" between units within a piece (Roy 2003: 345). A hierarchical view as aposed to a vertical view. Within the category of stratification there are: figure, emphasis, foreground, accompaniment, tonic polar axis, complex polar axis, movement and background.

Processes

The functions within the processes category are used to describe units with a "movement towards an end" which have "teleological" characteristics (Roy 2003: 347). Within the category of processes there are: accumulation, accelerando, intensification, dispersion, rallentando, attenuation, and spatial progression.

Rhetoric

The functions within the rhetoric category are used to "express relationships between units" (relation), if they reference or oppose one another, or if they cause a "disturbance in the musical flux" (rupture) of a work (Roy 2003: 348). For this reason the rhetoric category is split into two sub-categories of relation and rupture.

Rhetoric of relation

Within the category of rhetoric of relation there are: question, answer, announcement, reminder, theme, variation, anticipation, affirmation, reiteration, imitation, synchronous antagonismand successive antagonism.

Rhetoric of rupture

Within the category of rhetoric of relation there are: deflection, ellipsis, indice, articulation, retention, rupture and spatial location.

How can it be used?

Within the book Roy demonstrates how these functions can be applied to a transcription. He uses Francis Dhomont's piece Points de fuite within his explanation.
