Jazz Changes

Morgan Lewis, music · Nancy Hamilton, lyrics · Introduced in the Broadway revue Two for the Show

How High the Moon

How High the Moon is a 32-bar song from the 1940 Broadway revue Two for the Show. Each key turns minor to lead a whole tone down, and Parker's Ornithology reuses those changes. Jam sessions still play it, usually fast, though Lewis wrote it as a slow ballad.

How the tune works

G majorusual key
32 barsA · B · A² · C form
G · F · E♭ · G mkeys it moves between

Thirty-two bars in four sections of eight, A B A C, in G major. The A section steps down a whole tone at a time: two bars of Gmaj7, then Gm7 and C7 lead to two bars of Fmaj7, and Fm7 and B♭7 lead toward E♭. The B section opens on E♭maj7, passes through Am7♭5 D7♭9 to a bar of Gm7 and another Am7♭5 D7♭9, a short stay in G minor, and comes home with Gmaj7, Em7, Am7 and D7. The A section then returns unchanged. The C section begins like the B, with E♭maj7 and Am7♭5 D7♭9, but lands on Gmaj7 and finishes with a run of cadences: Am7 D7, Bm7 E7, Am7 D7, G6, and a last Am7 D7 that leads back to the top.

The 32-bar chorus in G, four bars to a line: A (bars 1–8), B (9–16), A (17–24) and C (25–32). Where a bar holds two chords, each gets half the bar.

Taken from the chord chart on standardrepertoire.com (medium swing, common key G, 32 bars, form ABAC). The sheet writes half-diminished chords as Aø7 and major sevenths with a triangle; they are spelled Am7♭5 and maj7 here. It has no intro and no tag. Other charts differ in the second half of the B section: the Weimar Jazz Database transcription of Pepper Adams's solo on Chet Baker's Chet (1958) plays bars 11 to 16 as Gm7, Gm7, G7♭9, Cmaj7, Bm7 B♭7 and Am7 D7, and writes D7 in bar 10 where this chart has D7♭9. JazzStandards.com labels the form A B1 A B2, describes a descending progression in which each tonic turns minor to lead a whole step down, and notes a brief passage in G minor in bars 11 and 12, which this chart shows. The chart is a single published sheet, so compare it with the one you play from and with the recording. Use the key buttons to move the chart to the key you play in.

The path starts with Benny Goodman's 1940 hit and the Les Paul and Mary Ford multitrack record of 1951, then follows the changes through Ella Fitzgerald's Berlin scat chorus, Parker's Ornithology, a Don Byas quintet, Chet Baker's sextet, Bud Powell's trio and a live Jeff Beck tribute to Les Paul. Each step gives you one thing to hear and one thing to try.

  1. Step 1 · Learn the song Now playing

    Benny Goodman and His Orchestra, vocal by Helen Forrest 1940

  3. Step 3 · Hear a scat chorus Now playing

    Ella Fitzgerald with the Paul Smith Quartet 1960

    Ella in Berlin: Mack the Knife

    Solos by Parker on alto, Lucky Thompson on tenor and Miles Davis on trumpet, at about 225 beats a minute. Listen for the three solos in turn, and for Arvin Garrison's guitar in the rhythm section.
    Try this
    Play bars 5 to 8 of the chart (Fmaj7, Fmaj7, Fm7, B♭7) a few times at a slow tempo, then listen to the record and find where those bars fall in the first chorus. Smaller version: play only the root of each chord.
  5. Step 5 · Hear a tenor saxophone take Now playing

    Don Byas Quintet 1945

    Listen for
    Don Byas leads on tenor saxophone. After the vocal records in steps 1 to 3, hear how the changes sound with a horn out front and no singer.
    Try this
    Play bars 9 to 16 of the chart slowly: E♭maj7, Am7♭5 D7♭9, Gm7, Am7♭5 D7♭9, then Gmaj7, Em7, Am7, D7. Smaller version: play only bars 9 and 10.

  8. Step 8 · Hear the song come back around Now playing

    Jeff Beck with Imelda May 2010

    Rock 'n' Roll Party
