"Practice makes perfect and continued practice makes you more perfect?"
Some new research out of Colorado has indicated that even after learning and mastering an action, continued practice can make you more efficient at that action. So there is apparently continued benefit from extra practice above and beyond just learning the action!
This is important because many music therapy clients are re-learning motor function or learning new motor functions during adapted music lessons. So even after a client sufficiently masters walking, playing a scale, hitting a target on a drum, etc., there still may be a good reason to continuing that practice.
Since extra practice has now been determined to be a valuable way to become more efficient, we also need to remember that music is a great way to promote repetition without losing motivation. See how far you can ride in your next spin class without music as a foundation!
