| | Semitone / semitone / 1/2-tone - musical interval |
 | | With the first letter capitalized and always with two decimal places in the number, a term often used by Joe Monzo to delineate 1200 logarithmic divisions of the octave, thus exactly analogus to Ellis's measurement of cents. |
| | With all letters in lower-case and no decimal places in the number, the term simply refers to a logarithmic division of 1/12 of an "octave", or one degree or "half-step" in the familiar 12edo scale. |
| | The term "semitone" is also used loosely in a general sense to indicate any interval of approximately 100 cents -- or even more generally, approximately half of a whole-tone -- including the limma, apotome, and many others. |
