Random notes

4 – Random notes
Practice playing random notes through the scale. For example:

Major scale = 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

Pick out notes randomly: 1 6 3 2 12 15 3 5 11 7 etc.

This will help you to learn the scale thoroughly, it will make you more flexible and again give you more freedom when improvising.
