fundamentennote

Fundamentennote is a term used in music theory and digital sound design to denote the pitch that serves as the foundational reference for a given musical system. It typically corresponds to the fundamental frequency around which a scale, tuning, or timbral mapping is organized. In practice, fundamentennote acts as the anchor for pitch-class mapping, harmonic relations, and modulation schemes within a composition or synthesis patch.

Etymology and usage: The word combines 'fundament' (foundation) with 'note', and is used primarily in European- and digital-tuning literature. It is not a standard term in classical music theory and appears mainly in niche microtonal and algorithmic contexts; different authors may define it slightly differently, but the common idea is a reference pitch that defines the pitch lattice of a system.

Applications: In tunings and scales that deviate from equal temperament, setting a fundamentennote allows synthesis engines to generate harmonically related pitches from a single F0 value. It is also used in sampler and instrument design to anchor pitch-to-velocity mappings, transposition algorithms, and tuning presets. In algorithmic composition, altering the fundamentennote can produce global shifts of mood and color.

Variants and distinctions: Some authors distinguish between an absolute fundamentennote, fixed within a project, and a relative fundamentennote, which may shift with key changes. In tuning theory, it may correspond to the idealized F0 of a reference instrument, such as concert pitch A4 = 440 Hz, or to a chosen anchor in microtonal systems.
