Notice
The first chord name should be Amaj(#4)
Right hand fingering is importent for the 3/4 section the fingering should be p-a-m-i-a-m-i-p-a-m-i-p. For the 2/4 section the right hand fingering should be p-a-m-i-p-a-m-i
I believe this study should be felt in 3 large phrases. This first phrase ending at the long awaited change of the bass note. The second phrase ending at the change of the time signature and the third phrase of course ending at the end of the piece.
Within each measure it can be quite effective to apply a "falling" technique. This meaning that each bar has a slight accelerando letting each note "fall" onto the next while slowly gaining speed.
The chords are lovely and are built for the guitar so it's importent to let every note ring the entire bar, don't cheat any of the notes with poor left hand shifts.
(the dynamic changes should obviously be more smooth than the midi allows)
Finally, this is my interpretation of the piece so feel free to change it as suites you, I just find this arrangement particularly effective.
