File:Just perfect fourth on C.mid - Wikipedia

This media depicts a musical interval outside of a specific musical context. Intervals consist of an ordering of two pitches or pitch classes (no "distinctiveness"), may be used in compositions by multiple composers ("common material"), and may not be readily apparent as distinct in compositions. As such, a musical interval is a musical concept or technique, which is considered too simple to be eligible for copyright protection, or which consists only of technique, with no original creative input.
