Use Case 4: Contemporary Music Composition

Use Case 4: Contemporary Music Composition

The performing arts combine both the communicational (expressions, emotions, etc.) and control aspects (triggering actions, controlling continuous parameters). The performer is both a trigger and transmitter connecting perception,gesture and knowledge. A few years ago, the electronic synthesizer was a revolutionary concept of a new music instrument that was capable of producing sounds by generating electrical signals of different frequencies by pianistic gestures performed on a keyboard. Nowadays, the music production still depends on musical instruments that are based on intermediate and obtrusive mechanism (piano keyboard, violin bow etc). Many years of studies are presupposed in order to obtain a good level to (a) control these mechanisms and (b) read and comprehend a priori defined musical scores. This long learning procedure creates gaps between non-musicians and music. Additionally, even the emotional status of the performer is expressed through extremely limited effective gestures such as "keystrokes", "grand détaché" (sustained strokes) or "martelé" (sharp almost percussive strokes). Nowadays, the need of a novel intangible musical instrument, where natural gestures (effective, accompanying and figurative) performed in a real-world environment together with emotions and other stochastic parameters for controlling non-sequential music, is increasing.

The case study of the contemporary music composition aims to develop a novel intangible musical instrument. This digital music instrument will be a novel Multimodal Human-Machine Interface for the music composition where natural gestures performed in a real-world environment will be mapped to music/voice segments taking into account the emotional status of the performer. Thus, ‘everyday gestures’ performed in space or surface together with the emotional feedback of the performer, will continuously control the synthesis of music entities. Those music entities can be a) music patterns of classic composers (i.e. Beethoven, Haydn or Mozart), b) natural and instrumental sounds or c) segments of speaking/singing voice. This intangible musical instrument will not be only addressed to experienced performers, musicians, researchers or composers, but also to users without any specific music knowledge. The heritage of the classic composers can this way be available for everyone; it can be better preserved and renewed using natural body and emotional interactions.
