In researching CPE Bach - Solfeggietto - cross-hand playing style?, I stumbled on the following statement in Wikipedia:
The work is often performed by left-hand alone.
Much of the piece is straightforward, and the fingering reasonably intuitive. However, there are some sections to watch out for and some requiring license.
mm. 3-4
These two measures require some wide leaps so may need extra practice for accuracy.
mm. 13, 15, and 25
The problem in these three measures is that the hand-span is too large (for anyone who can't reach a minor seventeenth -- 2 octaves + minor 3rd). There are a few options:
- Treat the notated left-hand notes as grace notes.
- Roll the chords.
- Change octaves.
Here is an illustration of m. 13 and it's options. Measures 15 and 25 are similar.
mm. 14, 16, and 26-29
These passages require careful fingering and then practice for accuracy. Fortunately, the chords are staccato; otherwise, the leaps to the high notes would be prohibitive for many of us.
Here's one possibility for m. 14.
mm. 22-24
In these measures, a whole-note is given in the left hand. To accommodate, either use some judicious pedal, or cut the note short -- two beats will be sufficient to communicate the intended effect.
