Practise! The bain of both music teachers and students alike. However, it is arguably one of the most important aspects of learning so no matter which side of the coin you are on, think on this, as perhaps it will make the world a little easier.
Efficient practice makes a huge difference to progression when playing an instrument. Imagine you could make three, four, five or even ten times as much progress to achieving your musical goals as you do now… and all in the same amount of time or even less!
It is a proven fact that we are at our most productive in the first 15 minutes or so of any practise session, so it stands to reason that after this time a rule of diminishing returns kicks in. Therefore next time you are practising, set an alarm and after 15 minutes or so go put the kettle on, do some weeding, basically do anything you don’t need to think about. This will give your brain time to absorb what you were playing much more efficiently. Go back 15 minutes later and repeat the cycle.
If you haven’t thought about this before, try it. I have yet to have a student it doesn’t work for.
