Pink Floyd - Don't Leave Me Now - Vinyl 1979

The main section of "Don't Leave Me Now", recorded with synthesizer bass, organ, piano, and a delay-treated guitar, does not adhere to one single key, but rather cycles slowly through four dissonant and seemingly-unrelated chords, for two measures of each: An E augmented chord, followed by a D flat major seventh chord, a B flat dominant seventh chord with a suspended second, followed by a G Major chord, which, after one bar, augments its fifth, before returning to the beginning of the progression. The first three chords all sustain the notes G♯/A♭ and C, and this interval is then lowered chromatically by one semitone for the conclusion on G Major. Furthermore, the roots of this chord progression (E, D♭, B♭, and G) outline the intervals of a diminished seventh chord. The roots relate to each other as a pair of tritones - the E and B♭ form one tritone, and the D♭ and G form the other. Musicologist and author Phil Rose described this section of the song as "entirely non-functional harmonically" and stated that "[M]ost of the time when a phrase ends, Waters is either singing one of the most dissonant notes in the accompanying chord, or a non-chord tone." There is no percussion, and the tempo is very slow.
