What changes in C Major 9
The open strings contain C, D, E, G and B, outlining a complete Cmaj9 colour without a dense close voicing.
Make the tuning sound intentional
Arpeggiate the open tuning, then move the low bass between C, A and F while keeping the top strings open.
Shape tip: Use the low C as a root and let D, B and E act as colour tones over changing bass notes.
Retune to C G D G B E safely
Only the sixth and fifth strings move down; a normal set is usually comfortable.
Change one string at a time, approach the target pitch gradually and recheck every string after the neck settles. Stop if a string feels unusually tight, the bridge lifts or the instrument reacts unpredictably.
