This composition is only 16 measures long using MIDI and audio samples. I started with vibraphones and then added nylon guitar, beats, tambourine, and a single tone from a bass; transposed them along the way in order to get the harmonies I wanted. Quite fun.
The resulting progression in 4/4 reads something like this:
Fm^7 | ” | Ab(add9) | ” | Abm9 | ” | E^7(b13,#11) | Gb6(#5) |
Db^7(#11) | ” | Abm9 | B^7 | A^13 | Ab(add9) | ” | ” | ” |
