A ukulele has four strings, so a 4-note chord uses every string for a different note — there is nothing left to double. Because the G string is tuned high (reentrant tuning), the lowest note you hear is usually on the C or E string, not the G.

Songs and Keys That Use A7

A7 belongs to one major key: D major (as the V chord).

  • ii – V – I — the central cadence in jazz
  • V – I — the strongest resolution in tonal music

A7 on Other Instruments

  • Guitar: see the A7 guitar chord — six strings, so the shapes are different, but the notes are the same.
  • Baritone ukulele (DGBE): 2223. A baritone is tuned like the top four strings of a guitar, so guitar shapes carry over and standard-ukulele shapes do not. Tune one with the baritone ukulele tuner.

Tune first

A right shape on an out-of-tune ukulele still sounds wrong. Check G, C, E and A in a few seconds.
