~~In [[just Intonation]],~~ '''~~1/1~~''' (~~also called the~~ '''~~unison''' or '''perfect prime~~''') ~~represents~~ the ~~base frequency from which an~~ interval ~~is measured~~. ~~As a frequency ratio~~, it is ~~simply 1~~. Measured in [[cent]]s (or any other logarithmic measure such as ~~millioctaves~~, [[EDO]] steps, etc.) it is exactly zero.

The '''unison''' (interval ratio '''1/1''') is the [[interval]] between two tones that are identical in pitch. In the [[harmonic series]], 1/1 is the 1st [[harmonic]].

Measured in [[cent]]s (or any other logarithmic measure such as [[millioctave]]s, [[EDO]] steps, etc.), the unison's size is exactly 0. This is because the distance between two identical pitches is zero. As such, the unison can be considered as a degenerate interval.

In [[just intonation]], 1/1 represents the base frequency from which an interval is measured.
