Diminished sixth (just) Play. In 12-TET, the interval is identical to a perfect fifth Play.

In classical music from Western culture, a diminished sixth (Play) is an interval produced by narrowing a minor sixth by a chromatic semitone.[1][3] For example, the interval from A to F is a minor sixth, eight semitones wide, and both the intervals from A to F, and from A to F are diminished sixths, spanning seven semitones. Being diminished, it is considered a dissonant interval,[4] despite being equivalent to an interval known for its consonance.

Its inversion is the augmented third, and its enharmonic equivalent is the perfect fifth.
