Feeling Good is a 32
bar song in the key of C major in the familiar AABA format. The
chord progression, which consists entirely of scale-tone triads
of the C major scale, is quite similar to @Paradise.au from Session 4. The first 4 chords of the two songs are identical
in their functions (I, VIm, IIIm and IIm) in two different keys
(C and Bb).
The melody of the first 4 bars of the 'Feeling Good' A section
is pitched at a distinctly higher level compared to the second 4
bars. A good ploy which can also be applied to create interest in
an improvisation.
