Proximity of Timbre: Blending Acoustic Instruments and Electronics by Ko Sahara

  • Published on 09/11/2026 by ks8

In mixed music for solo instrument and electronics, achieving acoustic-electronic timbral proximity is a key compositional strategy for creating extended sonic spaces. This presentation examines methods for blending these sounds—ranging from recording and computation to AI technology—from the dual perspectives of a composer and a computer music designer.

In mixed music, the choice of timbre is a critical decision for the composer. Especially in pieces for solo instrument and electronics, when electronic sound is treated not as mere accompaniment but as an extension of the instrument, the proximity of timbre between the two becomes a major compositional theme. This is because, from the perspective of instrumental extension, the auditory blending of electronic and acoustic sounds makes it possible to create a new sonic space that transcends the physical range and resonance limits of the instrument. In this presentation, I will examine the various methods used to achieve this timbral proximity, including recording, computation, and AI technology — from the perspectives of both a composer and a computer music designer.
