Music Theory Reference


Tones and semitones are used to measure distances between notes. The distances are called intervals. There is an interval of 12 semitones (or 6 whole tones) between two notes with the same name. Such an interval is called an octave.

2 Octaves on piano 2 Octaves on fretboard

Interval can also mean two simultaneously sounding notes.
