Note bashing tends to be used far too much as an easy option which can often result in injury – especially when there is a long hold on the music. Frequently the real problem in learning a new piece is analysis – an intellectual understanding of the structure of the music. This applies equally to any other other stressful form of playing. Practice scales and arpeggios for no longer than 10 minutes at a time, and these should be separated by playing forms which don’t stress the same antique piano muscles in the same way. Take frequent breaks in practice sessions, with movements and stretches that counteract the predominant playing positions, e.g. Weight lifting could result in muscle imbalances – aerobic sports which increase heart and lung efficiency are better. Mental tension and depression and their effect on the muscles.
