Noctave
The piece
In the original, three violins play exactly the same melody, two bars apart, over a two-bar ground bass; Pachelbel followed it with a gigue, rarely played today. A single piano has to choose: this version, arranged for Noctave after the Mutopia Project edition and checked against Max Seiffert's (1929), gives the first violin to the right hand and the bass, with its fifth, to the left. The second violin joins in where it enters, so that you hear the canon.
The variations follow one another without a break: quarters, eighths, sixteenths and thirty-seconds, then the lines of repeated notes, written here as eighths to stay playable. Each time the note values change, count a bar ahead so you don't speed up. In bars 5 to 8 the right hand holds two voices: the upper one sings, the lower one stays in the background. The left hand repeats the same pattern for fifty-seven bars; once it runs on its own, all your attention can go to shaping the melody.
