One letter per note
One more look at what you missed.
Every black key has two names.
The key between F and G is F sharp, and also G flat. Same key, same sound, two names.
A major scale uses each of the seven letters once.
In G major: G, A, B, C, D, E, and the seventh letter must be F. So that black key is F sharp.
Could the seventh note of G major be called G flat?
Find the black key between F and G.
In G major, call it F sharp. Then find the black key between A and B.
Same rule in F major: B flat, not A sharp.
F, G, A, and the fourth letter must be B. A sharp would use A twice.
The fourth note of F major: A sharp or B flat?
With one letter per note, a scale reads like a ladder.
Every letter comes once and in order, so you see each step at a glance.
D major goes D, E, then a black key. Which name?
You can spell a major scale.
What you learned
- Every black key has a sharp name and a flat name.
- A major scale uses each of the seven letters exactly once.
- That rule picks the name: F sharp in G major, B flat in F major.
