How do you finger C#maj7 on piano?
1-2-3-5 with the pinky on the 7th keeps the half-step rub at the top under the strongest reach; the compact lower thirds sit under 1-2-3 with no stretch.
The root is a black key — let the longer fingers (2, 3) own the black notes and keep the thumb toward the white keys where the shape allows.
Tip: the common mistake
Doubling the root on top, a half step above the 7th — that turns warmth into a sharp clash. Let the 7th be the top voice, or keep the root only in the bass.
