The scale on the neck

Here's C♯ Blues over the first 12 frets of the ukulele (standard gCEA tuning). The pink notes are the root; tap any note to hear it, or play the whole scale ascending.

These notes already sound. Make it interactive for the full neck and the intervals.

Press Make it interactive and the same scale opens on a ukulele neck — all 15 frets, the low-G and baritone tunings, and each note labelled by its interval from the root (R, ♭3, 4…) instead of by name. The numbers are the same in every key, so what you learn here transposes straight to G or E. (Note: the root shows there as R.)

Standard gCEA high-g tuning (soprano, concert, and high-g tenor). The g string is re-entrant — a high note, not a bass — so scale runs cross strings differently than on guitar. Because g is high, ukulele scales are usually played as a box across all four strings rather than one long run up a single string: look for the nearest lit note on an adjacent string. Baritone (DGBE) uses different shapes.

The notes

Each note is labelled with its scale degree. The formula (1 ♭3 4 ♭5 5 ♭7) is the scale's fingerprint — identical in every key.

How it's built & how it sounds

C♯ Blues is a six-note scale — minor pentatonic plus the “blue note”. What makes it different: The minor pentatonic with one chromatic “blue note” — the ♭5 — slipped in between the 4th and the 5th.

The sound: Gritty and expressive — that ♭5 is the “cry”. It's a passing tone: lean on it, bend through it, but resolve it. Where you'll hear it: Blues, rock and jazz, usually as extra colour passing through pentatonic lines.

How do I play C♯ Blues on ukulele?

Use the fretboard above — each lit note is in the scale. Because the ukulele's g string is re-entrant (a high note, not a bass), the notes don't climb in a straight line like a guitar; the map shows exactly where each one sits.

What is the formula for the blues scale?

1 ♭3 4 ♭5 5 ♭7 — the step pattern 1½–W–H–H–1½–W. It's the same in every key.
