B Blues scale on ukulele
The B Blues scale across the gCEA ukulele neck — notes B D E F F♯ A — on a tap-to-hear fretboard, with the formula and how it sounds. Free.
The scale on the neck
Here's B 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.
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
B 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.
