“Equipentatonic” scales are scales with 5 roughly equally spaced tones per octave. These occur in many tunings around the world, most famously slendro scales. They are usually not exactly equally spaces, but deviate from equal by small amounts.

An exactly equal equipentatonic scale is 5edo, which is popular with modern Western xenharmonic composers. Sevish recommends it as a tuning for those newly exploring beyond 12edo.
