Diminished fourth: Cultures & Overview

In classical music from Western culture, a diminished fourth (Playⓘ) is an interval produced by narrowing a perfect fourth by a chromatic semitone. For example, the interval from C to F is a perfect fourth, five semitones wide, and both the intervals from C♯ to F, and from C to F♭ are diminished fourths, spanning four semitones.
