small octave
(smal AHK-tiv)


[Eng.]

Under the Helmholtz Octave Designation System, a name applied to the octave which extends from c in the bass clef staff to b on top of the bass clef staff. The notes are indicated simply by lowercase letters (c, d, e, f, g, a, and b).

This octave can also be designated as the 3rd octave under Acoustical Society of America system (i.e. C3). The MIDI Octave Designation System has two versions, one where note 1 (8.176 Hz) is octave "0" making the Small octave the fourth octave (i.e. C4), and the other with note 1 (8.176 Hz) at octave "-2" making the Small octave the second octave (i.e. C2).
