If you are traveling along nicely and find yourself suddenly stuck on a piece of music and making no real progress, Here is a list of things to try. I have used them all with success. Please add the list if you have a technique that works for you.
MUSIC BLOCK TIPS
listen to the piece (press s)
change views up a level so you can read the notes further ahead on the screen
play something harder, when you go back to it it WILL be easy!
Sing it in solfege (in key optional but prefeable for all listening )
wait 2-3 days and try again
play it with unlabeled notes view 2,4,5,6, when you go back to labeled notes it will look easy!
play Fruit Lines instead (yes, give up for a while)
