I promised to look out some exercises for presto sections using the hands alternately (like a fantasia) using 16th and 32nd notes. I'm sure around 30 years ago, I came across such a set of exercises by Stephen Heller, but cannot find anything like it at the moment. It needs to be suitable for someone currently playing at around grade VI or VII.

If anyone can tell me what the exercises are, I'd be very grateful - alternatively some suggestions would be useful. Many thanks in advance
