Diminished octave  Play (help·info).

In classical music from Western culture, a diminished octave ( Play (help·info)) is an interval produced by narrowing a perfect octave by a chromatic semitone.^[1] As such, the two notes are denoted by the same letter but have different accidentals. For instance, the interval from C4 to C5 is a perfect octave, twelve semitones wide, and both the intervals from C4♯ to C5, and from C4 to C5♭ are diminished octaves, spanning eleven semitones. Being diminished, it is considered a dissonant interval.^[2]

The diminished octave is enharmonically equivalent to the major seventh.
