Frequently asked questions

Questions about this ukulele circle

Why does the open third string in F minor ring so fully?

The open C is the perfect fifth of F, giving the chord prolonged acoustic sustain that enriches the ukulele tone.

How do you switch smoothly between D flat and B flat minor?

Keep the fret 1 barre anchored and simply shift finger 3 to fret 3 of string 4.

Why is C7 such a relaxing chord in this circle?

Because it only uses a single finger on fret 1, allowing the hand to release tension before heading back to F minor.
