The Mandolin Diaries - some hip 7th chords to use on "Assanhado"

Jacob do Bandolim's "Assanhado" is one of those tunes - like "Sweet Georgia Brown," "There Is No Greater Love," "Lazy River" et al - that can be a veritable study in dominant 7th chords. The tune is in A, but sooner or later you run through Bb7, F7, C7, G7, D7, A7 and E7. What with all the chord voicings available on mandolin in GDAD tuning, there's a lot to explore. Here's some hip 7th and 9ths for the B-section.

Then some arpeggio exercises which should be self-explanatory. You can also do these diatonically.
