| The B section is a virtual solo for secondo, with primo finishing the melodies with scale passages in octaves. |
| Far from the old-style duet where the secondo is merely playing backup for the primo, this duet features a wonderful dialogue between the parts. |
| The secondo player gets the melody in measures 17-24, so balance is important. |
| The primo part always contains melodic material, while the secondo part contains mainly accompanimental passagework. |
| The primo and secondo parts are usually equal in difficulty and share melodic interest. |
| Its arrangement for four hands, however, is excellently done, with commendable attention to the interests of the secondo player. |
