Watch the Satin Chord Melody online guitar lesson by Frank Vignola from Essentials: Jazz Standard Soloing
There's a bunch of 2-5's in this classic AABA progression. In the key of C, it starts with Dm7 to G7, up to Em7 to A7, then chromatically we move down from Am7-D7, Abm7-Db7, C7-B7-Bb7-A7, into the next A section. The bridge starts on Gm7-C7 to Fmajor, then Am7-D7 to G7 and back to the final A section.
Chord melody is the solo concept here. Staying true and respectful to melody, I used the same kind of phrasing but featuring the 9th. As you notice, in chord melody we don't have to play big full chords. We could use chord fragments since there is bass. Then I use a common tone on top of the chord (G note) while moving chords down chromatically from C7 to A7.
