Jazz Changes

Herbie Hancock, music · Jon Hendricks, lyrics · First recorded for Blue Note, 1962

Watermelon Man

A sixteen-bar blues in F that Herbie Hancock wrote for his first album, Takin' Off, in 1962. The form is a short blues that is easy to learn, and players have reworked it in many styles. Mongo Santamaría's 1963 hit and Hancock's 1973 funk remake on Head Hunters carried it to wide audiences.

How the tune works

F majorusual key
16 barsA form
Fkey centers

Each chorus is sixteen bars in F, in four lines of four bars. The first eight bars follow an ordinary blues: four bars on F, two on B♭, two on F. The last eight run longer than a blues ending. They alternate C and B♭ for six bars, then settle on F for two. The same sixteen bars repeat for the melody and for each solo. The 1973 Head Hunters remake adds an eight-bar section.

The usual changes in F, sixteen bars. The first eight bars are an ordinary blues. The last eight alternate C and B♭, then settle on F.

Bar 16: F7♯9

The source writes the tonic as F7♯9 and the other chords as B♭9 and C9. Many players use plain F7, B♭7 and C7, and recordings vary. The source also prints A♭13 above the F7♯9 in bar 15 without explaining it, and that chord is left out here. The source marks the groove as even eighths. Hancock's 1973 remake adds an eight-bar section that this chart does not show. Use the key buttons to move the chart to the key you play in.
