Watch the Movable Usable Scale Form online guitar lesson by Erich Andreas from Nashville Number System Decoded

This major scale form 1 can be played in any key, starting from either a sixth string OR fifth string root, so it's a VERY movable and usable scale. This scale is the most used scale in the history of music! You can use it in any key and in fact is the basis of all jazz modal theory. It's also a great exercise, but most importantly for THIS course, this form will help us quickly identify the number and root note of our commonly used chords for any/all keys. It's VERY powerful, so please have it memorized and be able to play it up and down the fretboard using both sixth and fifth string roots.

VERY IMPORTANT: Don't forget to count the numbers up/down as you are playing this scale.
