B Major scale on ukulele
The B Major scale across the gCEA ukulele neck — notes B C♯ D♯ E F♯ G♯ A♯ — on a tap-to-hear fretboard, with the formula and how it sounds. Free.
The scale on the neck
Here's B Major 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, 2, 3…) 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 2 3 4 5 6 7) is the scale's fingerprint — identical in every key.
How it's built & how it sounds
B Major is the reference scale every other scale is measured against (mode 1, “Ionian”). What makes it different: Nothing — this is the ruler. Every other scale on this site is described by how it differs from the major scale. Its step pattern is W–W–H–W–W–W–H, and starting on C it lands on the white keys: C–D–E–F–G–A–B.
The sound: Bright, resolved, “at home”. The default happy sound of Western music. Where you'll hear it: Most pop, folk, country and classical music; the default major-key sound and the foundation of all the modes.
