These scale maps use standard re-entrant g–C–E–A ukulele tuning. Because the fourth string is usually a high g, a shape does not climb in pitch from left to right as it would on guitar or bass. Follow the actual note names in each diagram and listen to the pattern on its detail page. Every scale page also explains the interval formula and shows positions that connect across the neck.
The highlighted dots mark the root, the note that makes the pattern sound settled. Begin and end there while learning a position, but do not treat it as the only starting point for a melody. Play one string at a time, notice where notes repeat, and connect neighbouring positions with the closest available note. Low-G players can use the same pitch collection, although the octave order on the fourth string will differ.
These scales cover familiar major, minor, blues and modal colours in practical keys:
Play C major over C–F–G–C and A natural minor over Am–F–G–Am. The two scales contain the same notes but make different roots feel like home. Use A blues minor to create short call-and-response phrases over a twelve-bar groove, then try D Dorian over Dm–G. Keep the rhythm simple, leave space between phrases and aim for a chord tone on each change. That makes the scale sound connected to the song instead of like an exercise.
