Although this ratio [45/32] is composed of numbers which are multiples of 5 or under, they are excessively large for a 5-limit scale, and are sufficient justification, either in this form or as the tempered "tritone", for the epithet "diabolic", which has been used to characterize the interval.

It is not possible to decompose a diminished fifth into three adjacent whole tones. is called transposition. Using the notes of a chromatic scale, each tone can be divided into two semitones: For instance, the tone from C to D (in short, CD) can be decomposed into the two semitones CC and CD by using the note C, which in a chromatic scale lies between C and D. This means that, when a chromatic scale is used, a tritone can be also defined as any musical interval spanning six semitones: According to this definition, with the twelve notes of a chromatic scale it is possible to define twelve different tritones, each starting from a different note and ending six notes above it. narrowed) because it is smaller than most of the fifths found in the scale (they are perfect fifths).
