Herbie Hancock · 1965 · no single key · Modal AABA, 32 bars
Four bars each of two suspended dominants, and neither one ever resolves its suspension. The chord that in every other tune means tension here means stillness, because nothing follows it that would cash the tension in.

This is a short excerpt quoted for analysis, not the full chart, and this composition is very likely still in copyright. Published versions and recordings disagree with each other about the rest of the tune, and often about these bars too.
Every one of these tunes is assembled out of the same handful of harmonic resources. Jazz Harmony is those resources, explained in the order in which they build on each other.
| Chord | Roman numeral | Function | What it is doing | Confidence |
|---|---|---|---|---|
| D7sus4 | V7/vi | Dominant | D7sus4 is functioning as V7/vi: a secondary dominant. It is the dominant of G, not of the home key, so it borrows the pull of a V-I and points it at vi instead. | Low |

| F7sus4 | V7 | Dominant | F7sus4 is the dominant of Bb. Its third and seventh form a tritone, and that tritone is what makes the tonic feel due. | High |

The progression stops on the dominant of Bb — a half cadence. It is unfinished on purpose.
High, medium and low next to each numeral are judgements about musical context, not probabilities. A low rating marks a bar that can honestly be read more than one way. How the ratings are decided →
Numbered against Bb major, the excerpt is V7/vi – V7. Inside those 4 chords there is at least one secondary dominant and a chord borrowed from the parallel mode. Play it slowly and hold each chord until you can sing the note that wants to move. In a progression with no dominant, that note is what carries the phrase. Blues for Alice, All Blues and So What use the same device, which is the argument for learning it once properly rather than three times by accident.
Four chords, eight bars each, thirty-two bars in total, and every one of the four is a suspended sonority that refuses to declare whether it is major or minor. Because none of them resolves, the form has no gravitational centre — the chords are a sequence of places rather than a path to one. The written melody uses very few notes and long values, which is the correct model for improvising on it: the piece rewards patience and punishes anyone who tries to fill it with the vocabulary that works on cadences.
Recorded by Herbie Hancock in 1965 as the title track of an album whose pieces were all conceived around the sea. The quartet of suspended chords was unusual enough at the time that the tune is routinely cited as a turning point in how jazz composers used ambiguity. It has since become a standard, which is slightly odd for a piece with no cadence in it, and it is now often a student’s first encounter with music that cannot be analysed in terms of arrival.
Open these chords in the analyzer and change them. Move one chord, substitute a dominant, take the ii away — the reading updates and tells you what you just did.
