Harmonic field of Bb major on ukulele

Bb major: Bb – C – D – Eb – F – G – A. In the shapes below, the tonic opens with the bass on D. On the ukulele, the high reentrant G makes every shape light — and with four strings, every note is exposed. Its soft nylon strings sound warm and mellow, light enough to float gently over a song.
