Most pieces are based on scales, so when you already know your scales it makes learning new repertoire a piece of cake.
Scales can help your fingers to develop the agility and strength needed to play the piano with ease and up to tempo.
Playing the piano requires coordination between the two hands and practicing scales is a great way to develop this.
Scales help to build up muscle memory that you can use to find your way around the keyboard quickly without looking.
Through scales, you’re also learning about the key signatures and how different keys feel under the fingers.
Scales also allow you to improvise. If you know your scales you get to create your own music and embellish others’ music
