A♭ (A-flat; also called la bémol) is the ninth semitone of the solfège.
It lies a diatonic semitone above G and a chromatic semitone below A, thus being enharmonic to G♯, even though in some musical tunings, A♭ will have a different sounding pitch than G♯.

The Prelude Op. 28, No. 15, by Frédéric Chopin, known as the "Raindrop" prelude, is one of the 24 Chopin preludes. It is one of Chopin's most famous works. Usually lasting between five and seven minutes, this is the longest of the preludes. The prelude is noted for its repeating A♭, which appears throughout the piece and sounds like raindrops to many listeners.
