What’s My System?

There are eight notes in the scale.
If you have difficulty remembering the letters, give each one a number

Lets just say you were playing a song in the key of C, then C is the root note and the root note is 1.

C 1
D 2
E 3
F 4
G 5
A 6
B 7
C 8

Just so you don’t get confused C is both 1 and 8.
In technical speak thats called an OCTAVE (meaning eight)
