The term "equianharmonic" generally refers to a relationship in music theory regarding scales, particularly concerning the structure and tuning of musical intervals.

One common example relates to the "equianharmonic" concept in the context of different tunings that make different intervals sound similar in terms of harmonic function, even if their pitches differ.
