On the ukulele, the high reentrant G makes every shape light — and with four strings, every note is exposed. In this position the bass is Eb and the shape sits at fret 3, ringing 1 open string. Because this instrument has fewer strings than C7(#9) has notes, one note — usually the fifth — is normally dropped without losing the chord's identity. Its soft nylon strings sound warm and mellow, light enough to float gently over a song.

Notes on C: C – E – G – Bb – D#Formula: 1 – 3 – 5 – b7 – #9

In the formula, the numbers count steps of the major scale starting from the note that names the chord; "b" lowers a half step, "#" raises one — and a slash names the bass note.

Where to use it: Blues, rock and soul with an intense sound.
