CadenzaG ninth, suspended fourth
G9sus4
Also written G11 · G9sus · F/G
Often written G11, or F/G: an F major triad over the root. The modern dominant — V of C major without the pull of a 3rd. Herbie Hancock's “Maiden Voyage” is built from chords like this one.
How pianists voice G9sus4
The same notes, laid out the way hands actually play them.
F over G Slash chord
1 · ♭7 · 9 · 4 — an F major triad in the right hand over G in the left. The triad brings ♭7, 9 and 11; the missing 3rd is what makes the chord float.
Dm7 over G Slash chord
1 · 5 · ♭7 · 9 · 4 — the same chord heard another way: a minor 7th on the 5th, with the root underneath.
