Questions
What notes are in the C Yo scale?

The C Yo scale uses the notes C, D, F, G, A (one octave; the pattern repeats at higher registers).

What's the Yo scale formula?

The Yo scale follows the interval pattern W W+H W W W+H, where W = whole step (2 semitones) and H = half step (1 semitone). Apply that pattern starting on C to get the C Yo scale.

What chords work over C Yo?

Try chord pairings derived from the scale's third, fifth, and seventh degrees as roots — they share the most diatonic notes.

How do I finger C Yo on Piano?

On piano, scales typically use a 1-2-3 / 1-2-3-4 thumb-under pattern for white-key scales. Black-key scales (F♯, G♭, etc.) shift the thumb-under positions onto white keys for ergonomic clearance. Hanon Exercise No. 1 and Czerny Op. 599 No. 1 work through the canonical pattern.

When would I use the Yo scale?
