Hi Stuart,Hey Phil,
Hanon really is a great way to get your fingers working but, if you haven't done it yet, throw away book 1 and concentrate on 2, scales and arpeggios in books 2 & 3. Because of the weak fingers, I used to do a warm up with book 2 which doubled the key strokes for the 5,4,3/1,2,3 segments.
I get my practice in these days by reading opera/vocal scores. Playing up to speed is not the goal. Slow practice is very helpful for any style. If you are playing Bach, Mozart and Beethoven should be considered.
Are you working on repertoire, reading skills or improvisation?
