The tritone is defined as a musical interval composed of three adjacent whole tones. TT = T+T+T. The tritone is a restless interval, classed as a dissonance.
A fourth is an interval encompassing four staff positions, while a fifth encompasses five staff positions. An augmented fourth and a diminished fifth are tritones.
|An augmented fourth (Aug4) or a diminished fifth (Dim5)|
Tritone resolution can be inward and outward.
|The augmented fourth resolves outward to a minor or major sixth.|
|The inversion of this, a diminished fifth, resolves inward to a major or minor third.|
