sectionpiano

Sectionpiano is an experimental keyboard concept in which a piano-like instrument is divided into two or more independently playable sections, each mapped to its own voice or timbre. The design enables a performer to produce multiple musical lines from a single instrument by routing notes to separate sound engines or sample sets. The concept emphasizes modularity, flexible timbral control, and spatial projection in performance.

Construction commonly combines a multi-section keyboard layout with electronic routing. Each section may contain its own action, strings, or digital sampler, and may be controlled via MIDI, CV, or dedicated electronics. Some implementations present the sections as side-by-side keyboards on a single console, while others place them in distinct modules connected by control cables.

Performance and notation: Players work with keyboard zones that divide the keyboard into regions or assign sections to specific timbres. Notation can require parallel staves for each section or a consolidated score with timbre-markings and color-coded cues, depending on the composer. Real-time timbre changes are a central feature of sectionpiano performance.

History and usage: The term emerged in contemporary music discourse as composers explored expanded sonorities and spatialization. Sectionpianos are primarily encountered in experimental and electroacoustic settings, where they serve to blend traditional keyboard technique with software synthesis, sample playback, and live electronics.

Reception and impact: As a niche concept, sectionpiano has been praised for its creative potential but criticized for practical challenges, including cost, maintenance, and the need for tailored notation and rehearsal. It remains largely within experimental and contemporary music contexts.
