Long hours of practice can cause backache for many people so remember to stand up and walk around at regular intervals to give your back a rest. Be aware of your posture when practising – are your shoulders tense? Are you leaning to one side? Try to be centered and balanced when you play and pay attention to any aches and pains. Slow, calm practice allowing for accurate precision in both hands is the most beneficial so aim for a quiet sense of focus, concentrating on the details and don’t play through any physical discomfort.
