Additional notes about the perfect unison's relationship to the subharmonic series and about its status as the fundamental from which both the harmonic and subharmonic series spring. |

The '''unison''' (interval ratio '''1/1''') is the [[interval]] between two tones that are identical in pitch. In the | 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]], and likewise in the [[subharmonic series]] 1/1 is the first [[subharmonic]]- this is because it acts as the fundamental to both series. | ||
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. | Measured in [[cent]]s (or any other logarithmic measure such as [[millioctave]]s, [[EDO]] steps, etc.), the unison's size is exactly 0.
