I have a student who swears by practising in 10-minute segments.
She counts them up and by the end of the week it’s not unusual for her to have done 2 or maybe even 3 hours practice.
OK it’s not much by Charlie Parker standards, and you might need to think about doing a bit more if you’re looking to become any sort of professional musician, but for an amateur looking to make steady improvement, this sort of time spent at the piano will go a long way.
So next time you’re struggling to find the motivation to sit down for an hour, or even half an hour, just do 10 mins. It might lead you to another 10 mins, or it might not, but 10 mins is better than 0 mins.
And sometimes it’s what we do on our off days that counts.
