Here are the chord progressions that I use to play the 1932 Cole Porter (pictured above) standard Night And Day The tune is played in a moderate 4/4 tempo in the Key of "E". The substitutions were intentionally made to create descending bass lines whenever possible. Each box below represents one bar. The chord fingerings I use (in a Standard tuning) are as follows: Cmaj7/G = 33200x; B7/F# = 2x120x; Emaj7 = 022444; E6 = 02x120; A#m7b5 = 6x665x; Am7 = 5x555x; G#m7 = 4x444x; Go7 = 3x232x; F#m11 = 2x2200; B7b5/F = 1x120x; Gmaj7 = 3x443x; and Emaj9 = 0x4444. For variation, try substituting the "Cmaj7-B7#5" or "Cmaj7-F#m7-B7" chord sequences for the "Cmaj7/G-B7/F#" chords in the first two bars of the A section. Also, try an alternate "Go7-A#o7-C#o7" substitution for the "Go7" chord. In the B Section, try substituting the "Gmaj7-Am7-Bm7-Am7" progression for the "Gmaj7" chord and the "Emaj7-F#m7-G#m7-F#m7" progression for the "Emaj7" chord.
