Delta-V (music)

Delta-V in music refers to the sudden change or movement in pitch, melody, or harmony within a piece. Think of it as a musical shift that creates contrast or emphasis—like moving from one note or chord to another quickly. It can evoke emotion, add tension, or lead the listener in a new direction. Composers use delta-V intentionally to shape the musical narrative, providing moments of surprise or resolution, much like a driver changing speed or direction to alter the journey. Overall, delta-V contributes to the dynamic flow and expressiveness of music.
