Pitchdriven

Pitchdriven is an adjective used in music technology and data-driven audio processing to describe a design principle in which pitch information—such as notes, pitch class, or melodic contour—acts as the primary driver of a system’s behavior. In practice, pitchdriven approaches encode rules or constraints around pitches before considering other musical dimensions such as rhythm, dynamics, or timbre. The result is content or output that tends to preserve tonal coherence, scale membership, and intervallic structure, even when transformed by generation or synthesis.

In algorithmic composition, pitchdriven methods generate musical material by manipulating pitch-related features: scale degrees, contour shapes, and harmonic relationships may dictate the allowed transformations or the sequence of events. Rhythm and timing may be derived from the pitch structure or treated as secondary, producing melodies that feel coherent within a chosen tonal space.

In audio processing and synthesis, pitchdriven configurations may condition model parameters on the instantaneous pitch, guiding spectral shaping or modulation in a way that aligns timbre with melodic motion.

Although the term is used in various circles, it is not universally standardized and can have different emphases—from strictly tonal generation to more flexible pitch-guided data mappings.
