Now the ideas get audible. This module builds your reference grid — the major scale — and puts it on the guitar one string at a time. You'll learn where note names and interval names come from (briefly borrowing a piano keyboard to make it clear), then play the scale along a single string while always knowing which scale degree is under your finger. Finally you'll meet the course's first visual model, the three-note fragment, and use it to turn the scale into simple melodies. It's the foundation the whole system is built on — and it's still free.
