Mon travail en composition se révèle avoir beaucoup d’affinité avec cette spécialité du génie civil qui consiste à explorer et évaluer le comportement des matériaux au voisinage de la rupture. Il privilégie les formes nettes, fortes et tranchées, les mouvements d’alternances et les jeux marqués de tensions et de détentes.
Les matières que j’utilise sont soumises à des contraintes, à d’énormes énergies, jusqu’à ce qu’elles se déforment, qu’elles éclatent, se métamorphosent. Jusqu’à leur point de rupture.

Untethered Sounds — Gilles Gobeil , La mécanique des ruptures
10 compositions québécoises: musique électroacoustique
Décidément, le Québec n’a rien à envier aux autres pays en matière de musique électroacoustique. En effet, la province regorge de compositeurs créatifs qui ne cessent de repousser les limites de leur discipline et d’être reconnus internationalement. Même si dans la majorité des cas, la musique de ces compositeurs se rapproche du style acousmatique que l’on peut entendre en Europe, il y a bel et bien quelque chose qui les distingue
Je vous propose donc une liste de dix œuvres incontournables par des compositeurs et compositrices d’ici afin de découvrir le panorama de notre production électroacoustique.

Le Québec électroacoustique
On dit que le gazon du voisin est toujours plus vert que le nôtre, mais quand il s’agit d’électroacoustique, croyez-moi, le Québec n’a rien à envier aux autres régions du monde. Accusez-moi de chauvinisme, je n’en ai cure

Pistes d’introduction aux beautés de l’électroacoustique
La musique électroacoustique est un goût acquis. Qu’on le veuille ou non, la radio et la télévision nous conditionnent à accepter un certain nombre de modèles musicaux (tonaux, rythmiques) comme étant
Avec cette piste d’écoute, je veux simplement pointer quelques titres qui m’apparaissent susceptibles d’encourager plutôt que de décourager, des titres qui ouvrent une porte sur un autre monde musical. Bien sûr, cette sélection ne peut qu’être subjective. Mais avec un peu de chance elle pourra servir de guide aux nouveaux enthousiastes du genre et aux apôtres qui cherchent des idées-cadeaux pour répandre la bonne musique. Après tout, la période des Fêtes s’en vient
Des passerelles
On développe généralement un nouvel intérêt par excroissance d’un intérêt précédent. C’est-à-dire que l’on explore un genre musical qui nous est inconnu parce qu’un intérêt connexe nous y a mené. C’est pourquoi, dans le cas des musiques électroacoustiques, des œuvres mixtes (bande et instrument) ou qui abordent un sujet concret peuvent fournir cette passerelle qui ouvrira les horizons d’un nouvel auditeur. Par exemple, les amateurs de récits de voyage trouveront dans le Corazón Road du duo

Spectro-morphological Structuring Process in Gilles Gobeil’s “Le Vertige Inconnu”
Introduction
The purpose of this analysis is to explain the perceived integrity of a work that continues to achieve a positive consensus among composers, students, and audiences, or what
This analysis makes use of spectrographs to document the sounding energy of
Below is a spectrograph of a basic attack-decay gesture

Attack-decay Archetype
The morphologies that exist within a sound are reflected on various structural levels of the composition. The generative role of the onset, the motion towards termination or a new onset, and the presence of sustain portions of the sound, or continuants, occur at the lowest structural level. Likewise, larger structures will move away from the generative onset gestures towards terminating gestures. As textural-carried material is concerned with internal motion and not with external goals, it presents the higher-level corollary of the continuant. At the highest structural level, texture and gesture work as a dynamic dichotomy, reflecting similar motion patterns found at lower structural levels.
Spectral Overview
The perception of sectional structuring is very common even among first time listeners in beginning electronic music classes. The work has been divided into five sections for this analysis. The dividing marks have been placed at the following times

Section A
A reverse attack-decay gesture opens the work, functioning as an anacrusis to the first descending attack-decay gesture. The opening gesture is extended from 2 to 5 seconds by several descending gestures (visible in the spectrograph below) before a second decisive descending attack-decay gesture signals the termination of the first gestural area. While the tessitura of the terminating gesture remains constant, the faster decay of the high frequencies creates a prolongation of the descending gesture, preparing the listener for the first texture-carried subsection.
Gesture-carried Subsection — 0:00 to 0:15
The first texture-carried area is delineated by the primary descending attack-decay motive, acting as an onset to the subsection. The main textural area consists primarily of mechanical iterations. A great deal of motion is visible in the spectrograph, but it is motion without direction. The attack-decay gesture terminating the texture-carried area is weaker than those heard previously. Thus the texture continues beyond the gesture until a second descending attack-decay gesture brings the subsection to a more decisive close. The terminating gesture itself exhibits the same construction as the higher structural levels, as illustrated below
First Texture-carried Area — 0:16 to 0:34

One of the curiosities of this composition is the collection of disparate sounding sources, particularly the presence of both naturally and mechanically produced sounds. In examining the second textural subsection, however, one discovers the morphological connection between the sounding sources. Textural areas throughout the work are dominated by repeated iterations – short periodic sounds without gestural direction. The second textural subsection consists primarily of insect noises sounding over a rooted pitch-space. However, a need for termination develops as the rooted pitch-space begins to climb in tessitura. It cannot continue indefinitely and therefore tension is created, transforming the texture-carried material into gesture-carried material. The gestural nature is reinforced both by tessitura and with an increase in aggregate spectral energy as the sounding objects increase in amplitude. A third sounding object is introduced between the frequencies previously occupied, complimenting the frequency spectrum to produce maximum effect. At 55 seconds the continuant stops with an interrupting gesture, clearly different than the preceding sounds due to its complimentary pitch-space. However, the terminating function is inconclusive since the gesture lacks the descending morphology of the primary onset/termination motive.
End of Second Texture-carried Area — 0:41 — 0:57
The tension created by the ambiguity of this gesture is increased by the silence that follows. At 58 seconds the interrupting gesture is repeated, followed by a strong descending attack-decay gesture, bringing the subsection to a decided close. Within the first minute of
0:51 — 1:03
The third texture-carried area contains a similar structural process to the first texture-carried subsection. An increase in spectral density creates motion away from the texture-carried continuant towards termination. A descending attack-decay gesture at 1:32 anticipates the final build towards termination. However, the gesture at 1:37 lacks the terminating spectral energy to bring the section to a close. It is followed by a return of the mechanical iterations, which function as a textural prolongation. The final terminating gesture is a strong descending attack-decay gesture, prepared sufficiently though the prolongation of the terminating gestures to act as a final decisive termination to Section A.
End of Section A — 1:31 — 1:46
Section A contains four subsections. The opening gesture-carried subsection serves to introduce the primary descending attack-decay motive. The following texture-carried subsection presents three important concepts
Section A — 0:00 to 1:46
Section B
Section B provides a contrast to the more gesture dominated section A. The gestures within section B fail to give a sense of direction and therefore function as what
The following subsection appears as a different sounding environment through the use of reverb and resonance. Also significant to this subsection is the strong presence of harmonic frequency spectra, contrasting with the inharmonic spectra that dominate most of the work. This transition to the second subsection of B is shown below. The resolution and color are varied to better highlight the harmonic spectra.

Iterations from another source, perhaps a flute or an air brake, are mixed with the more harmonic iterations. Like previous textural areas, the continuant moves towards termination through increasing spectral density. Underscoring the importance of the principle motive, one can now intuitively hear how the final descending attack-decay gesture fulfils the terminative function that the upward gesture, bisecting this section, could not.
Section B — 1:47 to 3:10
Section C
Whereas section B is marked by a lack of gestural direction, section C brings back the mechanical iterations with an increase in gestural direction. This forceful motion is interrupted by the descending attack-decay gesture and is followed by a return of the high-frequency iterations from section B. Another descending attack-decay gesture acts as the onset to a slow textural build, as previously heard in section A. As in previous instances, the strong gestural activity of this section cannot be easily concluded with a single gesture. For this reason, the textural section at 4:14 is heard as an extension of section C. This section is decisively concluded at 4:24 with the descending attack-decay gesture, indicating the onset of Section D.
Section C — 3:13 to 4:27
Section D
Like section C, section D serves to further develop both previously heard sounds and structuring principles. The textural iteration motif from section A returns in section D. The spectro-morphological connection between the mechanical sounds and insect sounds was presented in section A when they were introduced in consecutive textural subsections. Now

The role of the iterations is no longer textural. As they increase in amplitude they lead towards termination or a new onset. Their alignment serves not only to demonstrate their structural similarity, but also to increase the gestural direction. Their ultimate termination in the descending attack-decay archetype is strengthened by the careful alignment of this motive to the tempo of the iterations.

A second subsection of D is reminiscent of the slow textural build heard in section A. However, this motive is now combined with the sort of interrupting gesture heard in section A (0:55). Instead of being immediately followed by the concluding gesture, the gradual build starts again after the interruption, increasing the tension as the sectional termination is further postponed. Strong gestural activity terminates this build and acts as an onset to the return of the iterations, now in their new gestural role. The iterations move the listener to the climax of the work at 6:45, the strongest descending attack-decay gesture yet heard.
Section D, although containing previously heard material, is unprecedented in gestural activity. The direction towards termination never wavers as interruptions only serve to heighten the tension. Just as the interruption of the middle subsection at 5:30 serves to prolong the tension, the middle subsection itself acts as an interruption of the gestural iteration motive which dominates this section. The material presented in the opening of this work has been transformed into the primary engine of structural motion towards the work’s ultimate goal.
Section D — 4:37 to 6:57
Section E
The need for preparation and balance before termination demonstrated in the individual sections and subsections of the work can also be found at the highest structural level of the work as a whole. The sudden conclusion of this piece at 6:45 would be anticlimactic. Therefore, the final section presents a simple structural idea that is consistent throughout the work
Section E — 6:57 to 8:20
Summary
The continuity of this work is based on repeated and varied use of similar material
Spectral Overview
As stated previously, spectro-morphology describes but one aspect of a composition. Elements such as space and the meaning and contextualization of sounding sources may provide still deeper and richer insights into this work. However, spectro-morphology is the language of sonic experience. Masterworks of western music have traditionally been considered those works demonstrating skillful mastery of their fundamental materials, be they pitch/rhythm motifs or spectro-morphological motifs. Further, the development of these constructive materials into large-scale formal structures reflected on various structural levels is also a hallmark of craftsmanship. Finally, as

The last track is his most earlier work, without using sounds that you almost can find anywhere in the world for creating his atmospheres, he uses sounds that comes from synthesizers and electronics. Here you can hear which way he wanted to go to, and we must say that his later work where he plays in a magnificent way with sounds from our civilisation (street, home, industry…) is better for creating his musical worlds. A thick little booklet is added in this brillant CD, with full explanation of the artists and the tracks, in French and English.

Music is a temporal art. Fundamentally, the music of any style, in any historical period, serves to articulate the passage of time. We humans perceive the passage of time through that wonderful invention we call rhythm, which is also a form of cyclic repetition. What distinguishes human rhythm (and our own heartbeats) from mechanical repetition is that rhythm is always a deviation from the mechanical norm. It is the deviation from mechanical perfection that gives rhythm its ability to propel music forward in tirne, and it is the corresponding lack of any deviation that makes the ticking of a clock so static. It is not paradoxical to state that a clock cannot articulate time, it can only measure it.
Sculpture, in contradistinction to music, is about the articulation of space, light, and texture. Translate these domains into the sonic realm and the discussion revolves around space, reverberation, intensity, and timbre. These are the fundamental elements that Mr.
