Freebase(0.00 / 0 votes)Rate this definition: Tritone. In music theory, the tritone is strictly defined as a musical interval composed of three adjacent whole tones. For instance, the interval from F up to the B above it is a tritone as it can be decomposed into the three adjacent whole tones FâG, GâA, and AâB. According to this definition, within a diatonic scale there is only one tritone for each octave. For instance, the above-mentioned interval FâB is the only tritone which can be formed using the notes of the C-major scale. A tritone is also commonly defined as an interval spanning six semitones. According to this definition, a diatonic scale contains two tritones for each octave. For instance, the above-mentioned C-major scale contains the tritones FâB and B-F.
