2019-2020 - Piano Scale Practice Charts
I know a lot of people hate scales, I often get asked "why do we do these?" Scales are really useful to help develop correct technique and you are required to do them for exams!...not only that, music is full of them.
Hopefully this is a fun way to help practice them. :-)
