Music Theory
The pattern behind every major scale, and why the circle of fifths is the most important tool in harmony theory.
All 14 major scales follow exactly the same sequence of whole (W) and half (H) steps — no matter which root note you start on:
The half steps always lie between degrees 3–4 and 7–8. This pattern produces the typical bright, stable major sound. If you start the pattern on G instead of C, you inevitably get an F♯ — otherwise the half step wouldn't fall in the right place. Each new fifth degree adds exactly one accidental.
In the app (and in the staff notation above) chord tones (root, third, fifth — degrees 1, 3, 5) are highlighted in gold, while scale tones appear in white. The triad on the I degree — the tonic — is the harmonic foundation of every key.
