Summary

Instrumental Interaction V is a composition for three Karlax, ensemble, and electronics by Benjamin Lavastre. The work, which is the fifth piece of a cycle, explores interaction strategies between digital and acoustic instruments, focusing on gesture, real-time control, and layered musical structures. Premiered in 2025, it highlights new approaches to integrating digital instruments into ensemble performance.

The Karlax is a digital musical instrument developed in the early 2010s by the company Dafact. Held with both hands and resembling a clarinet, it is equipped with several sensors, such as continuous keys, pistons, an axis, and an inertial measurement unit.

Objectives

  • Encourage the integration of digital musical instruments into ensemble practice alongside acoustic instruments
  • Explore compositional strategies for interaction between digital and acoustic instruments
  • Develop idiomatic writing techniques for the Karlax

Timeline

February 17–21, 2025

Status: Complete (premiered February 21, 2025)

Approach

  • Bring together experts in digital instrument performance and acoustic instrumentalists
  • Develop compositional strategies within notated and conducted ensemble contexts
  • Experiment with innovative musical forms, playing techniques, and spatialization approaches
  • Use gestural morphologies (bouncing, undulating, rotating, etc.) as a basis for musical structure, represented by the performers’ movements and evoked through the music.
  • Explore interaction strategies such as “as one instrument,” “catch and expand,” and “catch and throw”, etc.

Outcomes & Impact

  • Creation and premiere of a new work for 3 Karlax, ensemble, and electronics in the Multimedia Room (MMR) at McGill University as part of the MNM (Montréal Nouvelles Musiques) festival organized by the SMCQ.
  • Advancement of knowledge on interaction strategies between digital and acoustic instruments.
  • Production of a documentary addressing artistic and technical challenges, featuring various protagonists, as well as an interview with Prof. Marcelo M. Wanderley.
