What Is Bebop Jazz? Meaning, Characteristics, Musicians and Records

Bebop, often shortened to bop, is a style of jazz that took shape in New York in the early 1940s and became the basis of modern jazz after 1945. It is played by small groups, usually saxophone, trumpet, piano, bass and drums, at fast tempos over complex, quickly changing chords, and the improvised solo is the main event: the band states the melody, each soloist improvises on its chord changes, and the melody returns at the end. Its main creators were alto saxophonist Charlie Parker, trumpeter Dizzy Gillespie, pianists Thelonious Monk and Bud Powell, and drummers Kenny Clarke and Max Roach. Unlike the swing music it grew out of, bebop was made for listening, not for dancing.

What Does “Bebop” Mean?

The word has no dictionary meaning. It comes from the nonsense syllables of scat singing. Similar syllables turn up on record long before the style existed: “bebop” is heard in McKinney’s Cotton Pickers’ “Four or Five Times” (1928), and the variant “rebop” on several recordings from 1939. Accounts of how it became the style’s name differ. Dizzy Gillespie said audiences picked it up from hearing him scat his new, still untitled tunes to the band, and he recorded a piece called “Be-Bop” in January 1945. Thelonious Monk said his “52nd Street Theme” was originally titled “Bip Bop.”

Where and When Did Bebop Start?

Bebop grew out of after-hours jam sessions in Harlem in the early 1940s. The most important was Minton’s Playhouse, in the Hotel Cecil on West 118th Street. Former bandleader Teddy Hill became its manager in late 1940 and put drummer Kenny Clarke in charge of the music, with Thelonious Monk as house pianist. Charlie Parker, Dizzy Gillespie, guitarist Charlie Christian and the young Bud Powell all played there. Clark Monroe’s Uptown House ran similar sessions, with Max Roach in the house band. The regulars called unfamiliar tunes at very fast tempos and reharmonized standards, partly to keep weaker players off the bandstand.

The style also developed inside big bands. Parker and Gillespie played together in Earl Hines’s orchestra in 1943, then in the band Billy Eckstine formed in 1944, often described as the first bebop big band. By the middle of the decade the music had moved downtown to the clubs of 52nd Street, such as the Onyx and the Three Deuces.

Why So Little Early Bebop Was Recorded

From August 1942 the American Federation of Musicians barred its members from making commercial records. Decca settled in September 1943, but Columbia and RCA Victor held out until November 1944, so most of bebop’s early development went unrecorded. On February 16, 1944, Coleman Hawkins led a session for Apollo, with Gillespie in the band, that produced “Woody’n You,” usually cited as the first formal bebop recording.

Money played a part too. In 1944 a 30 percent federal cabaret tax hit venues that offered dancing or entertainment beyond purely instrumental music, which made big dance orchestras expensive to book. It was one of several reasons the big-band business shrank, as WRTI’s account of the cabaret tax explains, and it favored small instrumental groups like the ones that played bebop.

Bebop Characteristics: What It Sounds Like

You can hear most of the style’s features in Charlie Parker’s “Ko-Ko,” recorded for Savoy in November 1945 and added to the Library of Congress National Recording Registry in 2002.

Fast Tempos

“Ko-Ko” runs at around 300 beats per minute, and Gillespie’s “Be-Bop” is almost as fast. Ballads and medium tempos stayed in the repertoire, but the fast numbers were where players proved themselves.

Extended and Substituted Chords

Bebop musicians treated the upper notes of a chord, the ninth, eleventh and thirteenth, as ordinary melody notes; Parker built many of his lines from those higher intervals. They used dissonant intervals such as the flatted ninth and the flatted fifth, and they reharmonized familiar tunes. A common move is the tritone substitution: a dominant chord such as G7 is replaced by the dominant a tritone away, D♭7. The two share their most important notes (B and F, the third and seventh of G7), so the substitute still leads to C, but the bass now falls by a half step. Our guide to jazz chord progressions shows how this works inside the ii-V-I.

Head, Solos, Head

A typical performance opens with the theme, or head, played by the horns together, often in unison, followed by improvised solos over the tune’s chords and a final statement of the head. Many heads were contrafacts: new, intricate melodies written over the chords of an existing song. Chord progressions cannot be copyrighted, so the new melody made the tune the composer’s own. Well-known examples:

• “Ko-Ko” (Parker) on Ray Noble’s “Cherokee”
• “Ornithology” (Parker and Benny Harris) on “How High the Moon”
• “Groovin’ High” (Gillespie) on “Whispering”
• “Hot House” (Tadd Dameron) on Cole Porter’s “What Is This Thing Called Love?”
• “Donna Lee” (credited to Parker, later claimed by Miles Davis) on “(Back Home Again in) Indiana”
• “Anthropology” (Parker and Gillespie) on Gershwin’s “I Got Rhythm,” the progression known as rhythm changes

A New Role for the Rhythm Section

Kenny Clarke moved the basic timekeeping to the ride cymbal and used the bass drum for irregular accents, which musicians called “dropping bombs.” The bassist carried the pulse with a walking line of four notes to the bar, and pianists gave up the stride left hand for short, irregular chords, known as comping, that answered the soloist.

Long, Chromatic Lines

A bebop solo is built from long runs of eighth notes that spell out each chord as it passes, with chromatic passing tones and enclosures (approaching a target note from a half step above and below). Phrases start and end in unexpected places in the bar.

Bebop Instruments

The typical bebop group is a combo of four to six players: alto or tenor saxophone and trumpet in front, with piano, double bass and drums behind them. J.J. Johnson was one of the first trombonists to play bebop, and Milt Jackson took it to the vibraphone after Gillespie hired him in 1945.

The guitar had a harder time, because its swing-era job of strumming four chords to the bar went to the piano. Charlie Christian, who played single-note, horn-like lines with Benny Goodman from 1939 to 1941 and sat in at Minton’s, showed the way before his death in 1942 at 25. Barney Kessel, who recorded with Parker in 1947, and Jimmy Raney, heard with Stan Getz’s quintet in 1951, later proved the guitar could speak the full bebop language. For every instrument in the music, see our guide to jazz instruments.

How Did Bebop Differ From Swing?

Most bebop players learned their trade in swing bands. The difference lay in what the music was for.

The shift also changed how the musicians saw themselves. Swing had been America’s popular music, with white bandleaders such as Goodman and Miller among its biggest names. In Blues People (1963), published under the name LeRoi Jones, Amiri Baraka described bebop as Black musicians reclaiming a music that white culture had commercialized. Bebop players wanted to be heard as artists, not entertainers.

The Main Bebop Musicians

Charlie Parker (alto saxophone, 1920 to 1955), nicknamed Bird, was born in Kansas City, Kansas, grew up in Kansas City, Missouri, and first came to New York in 1939. His phrasing, speed and harmonic invention set the terms of the style, and Birdland, the Broadway club that opened in December 1949, was named after him. He died in 1955, aged 34.

Dizzy Gillespie (trumpet, 1917 to 1993), from Cheraw, South Carolina, shaped bebop trumpet playing with fast runs into the high register, taught the new harmonies to other musicians and led his own bebop big band from late 1945. In 1947 he brought Cuban percussionist Chano Pozo into that band, which led to “Manteca,” a founding tune of Afro-Cuban jazz.

Thelonious Monk (piano, 1917 to 1982), born in Rocky Mount, North Carolina, was the house pianist at Minton’s. His playing used space, unexpected dissonances and off-center rhythms, and his tunes, among them “‘Round Midnight,” “Well, You Needn’t” and “Epistrophy” (written with Kenny Clarke), became core jazz repertoire.

Bud Powell (piano, 1924 to 1966), from Harlem, did for the piano what Parker did for the saxophone: fast, horn-like single-note lines in the right hand over sparse chords in the left. Bill Evans later named him as his single greatest influence. Both pianists are profiled in our list of the greatest jazz pianists.

Kenny Clarke (drums, 1914 to 1985) ran the music at Minton’s and pioneered ride-cymbal timekeeping and bass drum “bombs.” Max Roach (drums, 1924 to 2007) played on Parker’s first Savoy session in 1945 and in his late-1940s quintet, shaped his drumming to the melody of each tune, and in 1954 formed a quintet with trumpeter Clifford Brown. Both appear in our guide to the drummers who drove jazz.

Sarah Vaughan (1924 to 1990) sang in both the Hines and Eckstine bands and recorded “Lover Man” with Gillespie and Parker in May 1945. She carried bebop harmony into jazz singing and is often called the Queen of Bebop, the title of Elaine M. Hayes’s 2017 biography of her.

Five Bebop Recordings to Start With

1. Dizzy Gillespie and Charlie Parker: The 1945 Guild Sessions

Gillespie and Parker recorded two sessions for Guild in February and May 1945. The first produced “Groovin’ High” and “Dizzy Atmosphere”; the second, with Al Haig on piano, Curley Russell on bass and Sid Catlett on drums, produced “Salt Peanuts,” “Shaw ‘Nuff” and “Hot House,” plus “Lover Man” sung by Sarah Vaughan. “Salt Peanuts,” with Gillespie chanting the title, is the friendliest way in.

2. Charlie Parker: The Savoy and Dial Recordings

Parker’s first session as a leader, for Savoy on November 26, 1945, with Miles Davis, Curley Russell, Max Roach and Gillespie on piano and trumpet, produced “Ko-Ko,” “Now’s the Time” and “Billie’s Bounce.” In Hollywood on March 28, 1946, with Davis and tenor saxophonist Lucky Thompson, he recorded “Ornithology,” “Yardbird Suite” and “A Night in Tunisia” for Dial, the last with his unaccompanied alto break. The Dial sides are collected on the box set Charlie Parker on Dial.

3. Thelonious Monk: Genius of Modern Music, Vol. 1

Monk’s first sessions as a leader, recorded for Blue Note in 1947 and 1948 and first gathered on a 10-inch LP in 1951, introduced “‘Round Midnight,” “Ruby, My Dear,” “Well, You Needn’t,” “Off Minor” and “Epistrophy.” Art Blakey plays drums on the 1947 dates, and Milt Jackson adds vibraphone to “Misterioso” and “Epistrophy” in 1948.

4. Bud Powell: The Amazing Bud Powell, Vol. 1

Two Blue Note sessions: a quintet date on August 8, 1949 with trumpeter Fats Navarro and tenor saxophonist Sonny Rollins (“Bouncing with Bud,” “Wail,” “Ornithology”), and a trio date on May 1, 1951 with Curley Russell and Max Roach that produced “Un Poco Loco” and “A Night in Tunisia.” Later editions include all three takes of “Un Poco Loco.”

5. Dizzy Gillespie and His Orchestra: The 1947 RCA Victor Recordings

For RCA Victor in 1947 Gillespie’s big band recorded “Two Bass Hit” and, with Chano Pozo on conga, George Russell’s “Cubano Be, Cubano Bop” and “Manteca,” which Gillespie wrote with Pozo and arranger Gil Fuller. “Manteca” was the first jazz standard built on the Cuban clave rhythm and entered the National Recording Registry in 2004.

What Came After Bebop

Cool jazz, launched by the Miles Davis nonet sessions of 1949 and 1950 later collected as Birth of the Cool (Capitol, 1957), kept bebop’s harmony but used lighter tones and more relaxed tempos; see our guide to cool jazz. Hard bop, from the mid-1950s, added blues, gospel and rhythm and blues to the bebop language in the bands of Art Blakey and Horace Silver, as our piece on hard bop and the Jazz Messengers explains. Modal jazz, heard on Miles Davis’s Kind of Blue (Columbia, 1959), replaced bebop’s fast-moving chords with long stretches on a single scale; see how modal jazz works. For the full picture, see our overview of the main types of jazz.

Frequently Asked Questions

Is bop the same as bebop?

Yes. Bop is the short form of bebop, and both names refer to the small-group modern jazz developed in New York in the 1940s. Later styles such as hard bop and post-bop take their names from it.

Who were the most important bebop musicians?

Charlie Parker (alto saxophone) and Dizzy Gillespie (trumpet) are the two central figures. Thelonious Monk and Bud Powell were the main pianists, Kenny Clarke and Max Roach the main drummers, and Sarah Vaughan the leading singer. Fats Navarro, J.J. Johnson, Dexter Gordon, Tadd Dameron and Milt Jackson belong to the same first generation.

Who is called the Queen of Bebop?

Sarah Vaughan. She sang in the Earl Hines and Billy Eckstine bands alongside Parker and Gillespie, recorded “Lover Man” with both of them in 1945, and brought bebop harmony into jazz singing. Elaine M. Hayes’s 2017 biography of her is titled Queen of Bebop.

Is bebop hard to listen to?

It can be at first, because the tempos are fast and the solos move through many chords. Start with slower or medium-tempo pieces such as Monk’s “‘Round Midnight” or Parker’s blues “Now’s the Time,” and listen to the melody at the start so you can follow the soloists over the same chords. Then move on to fast pieces like “Ko-Ko.”
