How the chords connect in A major

The progression

  • A, F#m, Bm and E7 make up the A major circle, as degrees I, vi, ii and V7. At 88 beats per minute, each bar of 4/4 lasts about 2.7 seconds and the whole round about 10.9.

The notes of each chord

  • A holds A, C# and E. In F#m you hear F#, A and C#. Bm holds B, D and F#. In E7 you hear E, G#, B and D.

From one chord to the next

  • A and F#m keep A and C# in common. Also, two hand positions stay put. From F#m to Bm, F# stays, and one hand position stays put. Bm and E7 keep B and D in common. Also, two hand positions stay put.

Back to the start

  • Going back from E7 to A, G# rises a semitone to A and D falls a semitone to C#. The two chords share E.

The hand

  • A presses two positions and leaves two strings open. F#m rings with string 1 open and three fretted positions. Bm needs a barre at fret 2. E7 rings with string 2 open and three fretted positions. The highest fret in the circle is fret 4, in Bm. Bm uses a barre.

Frequently asked questions

Questions about this ukulele circle

Why is switching from A to F sharp minor so seamless on ukulele?

Fingers 1 and 2 stay completely in place while finger 3 drops right into fret 2 of string 2 without moving the hand.

How do you prevent muting the open string 2 on E7?

Keep the tips of fingers 2 and 3 strictly perpendicular to the fretboard so string 2 vibrates freely between them.

Which playing style best brings out the character of the A circle?

A 4-string fingerpicking arpeggio (p-i-m-a) highlights the ring of open chords set against the B minor barre.
