Rapter, I just posted a couple of improvs here:
A couple of improvs
They are pretty much all arpeggios, but not in the sense that most think about arpeggios. In this case, the chords in the tune are fairly complex, not all from the mother key and it's certainly not a matter of holding down a chord and playing the notes within. However, the melody consists of chord tones almost exclusively, with the odd passing tone or passing run here and there to link those chord tones up, so they are indeed arpeggios. Once you start working with extended chords, the number of chord tones increases and in tunes like this, you do wind up playing all 12 notes at some stage or other.
