How to play Gmaj7 (G Maj7) on Ukulele

Gmaj7 is the G maj7 chord. It is built from 4 notes — G, B, D and F# — which sit at the root, major third, perfect fifth and major seventh above the root G. Written as a formula that is 1P – 3M – 5P – 7M. Those intervals, not the note names, are what give the chord its character: move all of them to a different root and you still hear a maj7 chord.

Gmaj7 on ukulele is a barre shape. Your first finger lies flat across fret 2, and the remaining fingers build the chord above it. Barre chords are the usual sticking point for beginners. The fix is almost never more grip strength: roll the first finger slightly onto its bony outside edge, keep the thumb low and centred behind the neck, and press just behind the fret rather than on top of it. Because nothing is open, the whole shape slides up or down the neck to give you the same chord quality on a different root.

The major third between G and B is what makes this chord sound bright and settled. Flatten that one note by a semitone and you have G minor instead — a single semitone is the whole distance between the two moods. The added major seventh stops the chord from sounding like a resting place — it leans forward and wants to resolve, which is exactly why it turns up at the end of a phrase rather than the start.

Gmaj7 belongs to 2 major keys, including G major, where it is the I chord and D major, where it is the IV chord. That is the practical reason to learn it: a chord that is diatonic to several keys turns up constantly, and knowing which degree it occupies tells you what tends to come next. A I chord in G major most often moves toward the tonic, so practising Gmaj7 in the context of G will teach you more than practising it in isolation.
