for viola and electronics (2012)

World Premier at the Atelier concert of Cursus 1 IRCAM : Noémie Bialobroda (viola) Keita Matsumiya (electronic) Mikhail Malt (technic assistant)

When I write a piece for solo instrument or small size of chamber music, I always start by looking for the “nature” of each instrument. Reading of the treaties of instrumentation, reading scores, and exchanges with musicians involved in the construction of my work. What inspired me this time is the 24 Caprices of Paganini. As Brahms and Schumann, I am interested in his musical figures, body gestures of the musician and his instrument research. In relation to music perception, the proportions of envelopes or non-linear linear existed in various musical events have been particularly involved in the development of this study. As compositional technics, OpenMusic allowed me to generate certain proportions of envelope curve of three dimensions. This visualization has allowed me to create musical figures in the score and the electronics in real time and offline.

for harpsichord and electronics (2011)

Created by Bruno Martin at the Salle Fleuret Hall, in Conservatoire de Paris, Paris March 2011
Duration: 7 min.

” When I started this piece, I reflected on the different points of view from which may have addressed the composition for the harpsichord today.
First of all, I found it impossible to make sustained sound because of the nature of the instrument. This restriction sparked my interest in research around the ornamentation in the classics.
I am particularly interested in the work of Jean-Henry D’Anglebert, harpsichordist and composer of the early Baroque period, which has categorized many figurations and ornaments that he later included in his scores.
In a second time my interest has focused on temperament. The superposition of two temperaments, the Meantone and Kirnberger III, led me to develop a new scale microintervalles. Electroacoustic part consists mainly in the transcript of the characteristics of this instrument.
Patches and salaries in the software Max/MSP allows me to achieve agreements re-synthesized, that is to say, to set up an extended sound, imitating the rhythmic figure of the instrumental part. The accumulation intervals of the harpsichord is reinforced by the dynamics of electronics. In this piece the interaction is based on a combination of actions of the player with those of electronics. ”
