Noun

augmented fourth (plural augmented fourths)

  1. (music) A type of tritone in musical composition. It spans four diatonic scale degrees like a perfect fourth but with an extension of a chromatic semitone. The number of diatonic degrees it spans is what distinguishes it from a diminished fifth.
    e.g. C - F is a perfect fourth, C - F# is an augmented fourth, and C - F♭ is a diminished fourth.
    An augmented fourth on C:
    <c'fis'>1

Usage notes

Aurally and while using well temperament or 12-tone equal temperament, it is impossible to distinguish between an augmented fourth and a diminished fifth. For this reason one would call it a "tritone" in a context such as ear training, but distinguish between an augmented fourth and a diminished fifth when, for example, analysing a score.

In most other tunings, however, the augmented fourth and diminished fifth are of different sizes.
