What is harmonic planing?

Harmonic planing is a technique used in music theory and composition where chords move chromatically (i.e. by half-steps) in order to create a smooth, continuous sound. This technique is often used to create a sense of tension and release within a piece of music.

Harmonic planing can be achieved through a variety of different methods. One common approach is to move chords in parallel motion. For example, a chord progression might move from a C major chord to a B major chord to a B-flat major chord to an A major chord, creating a fluid and harmonically rich sound.

Harmonic planing can be found in a wide range of musical genres, from classical to jazz to pop music. It is often used by composers to create complex harmonies and to explore different tonalities within a piece of music.
