Third position in your tunes
The four notes you just learned — C, G, D, A — aren't random. They're notes you already know
by ear: the tonic and dominant of the G-major scale (Stage 4's the-twelve-keys territory),
just reached from a new place on the neck. This lesson is the bridge from "I can find 3rd
position" to "I can use it in something musical."
The same notes, a new address
Play it slowly enough to feel each shift land, and check the D-in-3rd-position against the
open D exactly the way third-position taught you.
Try it
Try
Play the fragment above. Then try inventing your own four-note pattern using only C (3rd position, G string), G (open), D (open), and D (3rd position, A string) — any order, any rhythm. This is real music-making with a genuinely new position, even before you have a full piece that calls for it.
The usual mistake
Treating 3rd position as a drill that only exists in exercises. The moment you can reliably land on these four notes, you can already use them musically — waiting for "real repertoire" before playing anything in a new position just delays the ear-and-hand trust that makes the position actually useful later.
