Chord & FretSecondary dominants and approach chords: the complete guide on ukulele
On the ukulele in G–C–E–A with a reentrant high G — the fourth string is high, not low — a secondary dominant is judged by ear, never by the shape: with no real low register, the tension concentrates in the middle voices and the top, where the chromatic leading tone often sounds like melody.

What changes on the ukulele
Reentrant tuning scrambles the visual order of pitches: the "top" string may be the second-highest note of the chord. In practice, the classic dominant bass move — the root falling a fifth — barely exists here as a low voice; the resolution is perceived through inner notes moving by half step. Play slowly, identify by ear which note is highest and which is lowest in each shape, and confirm that the leading tone is audible.
In return, the ukulele's seventh shapes are economical — several take one or two fingers — and the changes become fast. That makes the instrument perfect for chained dominants: sequences where each seventh chord is the dominant of the next.
Role in the arrangement and styles
Hawaiian music built an entire cliché on this: the circle turnaround, E7 – A7 – D7 – G7 landing on C, appears in countless traditional songs. In vocal accompaniment for pop and folk, a single secondary dominant before the chorus already shifts the expectation. In chord melody, the rule is to choose the shape by its top note: the melody must stay recognizable while the tension happens beneath it.
Common mistakes on the ukulele
- Trusting the "visually lowest note" as if it were the bass: with a high fourth string, the shape deceives.
- Using the same strum for every chord, erasing the arrival — the resolution deserves a touch of dynamics.
- Not noticing that the reentrant string may double the leading tone an octave up, making the tension shrill.
- Changing shapes without checking which note ended up on top: in such a high register, it dominates perception.
How do I suggest a walking bass if I have no low strings?
Accept that the role changes: instead of imitating a bass, let the inner voices make the half-step journey — that's what the listener uses to feel the resolution. If the arrangement calls for more weight down low, the instrument's low-G variant gives back part of that function.
Why do so many Hawaiian songs chain dominants together?
Because the chain around the circle of fifths — each seventh chord resolving into the next — creates continuous momentum with very little hand effort, something that suits the ukulele's light shapes. The ear knows exactly where the music is going, and the arrival still satisfies.
