In bebop as well as in hard bop, musicians use chords to provide the background for solos. A piece starts out with a theme that introduces a series of chords for the solos. These chords repeat throughout the whole piece, while the soloists play new, improvised themes over the repeated chord progression. By the 1950s, improvising over chords had become such a dominant part of jazz that sidemen at recording dates were sometimes given nothing more than a list of chords to play from.[2]
Mercer Ellington has stated that Juan Tizol conceived the melody to "Caravan" in 1936 as a result of his days studying music in Puerto Rico, where they could not afford much sheet music so the teacher would turn the music upside down after they had learned to play it right-side up.[3] This "inversion" technique led to a modal sound throughout Tizol's work.[3]
Sun Ra reportedly rehearsed a small group consisting of Harold Ousley, Vernel Fournier, and Wilbur Ware in 1950 that played original songs that were modal in which the melody was based on a single chord or vamp – ten years before this approach became popular in jazz.[4]
Saxophonist Wayne Shorter has noted that the 1953 composition "Glass Enclosure" by pianist Bud Powell was one of the earliest jazz compositions to make use of Lydian chords, based on the Lydian mode that was not widely used in jazz until about a decade later.[5] Powell's 1951 Un Poco Loco uses the lydian chords and even uses lydian chords stacked on top of each implying a polytonality (D major 7 over C major 7: CEGBDF#AC#) with the improvisation based on alternating lydian-ish polytonality and an altered dominant chord.[6]
Towards the end of the 1950s, spurred by the experiments of composer and bandleader George Russell, musicians began using a modal approach. They chose not to write their pieces using conventional chord changes, but instead using modes. Musicians employing this technique include Miles Davis, Freddie Hubbard, Bill Evans, Herbie Hancock, and Wayne Shorter.
Among the significant compositions of modal jazz were "So What" by Miles Davis and "Impressions" by John Coltrane.[9] "So What" and "Impressions" follow the same AABA structure and were in D Dorian for the A sections and modulated a half step up to E-flat Dorian for the B section. The Dorian mode is the natural minor scale with a raised sixth. Other compositions include Davis's "Flamenco Sketches", Bill Evans's "Peace Piece", and Shorter's "Footprints".[9]
Davis recorded one of the best selling jazz albums of all time in this modal framework. Kind of Blue is an exploration of the possibilities of modal jazz.[10][9] Davis acknowledged the crucial role played by Bill Evans, a former member of George Russell's ensembles, in his transition from hard bop to modal playing. Although his explorations of modal jazz were sporadic throughout the 1960s, he included several of the tunes from Kind of Blue in the repertoire of his second quintet.
Coltrane took the lead in extensively exploring the limits of modal improvisation and composition with his quartet, featuring Elvin Jones (drums), McCoy Tyner (piano), and Reggie Workman and Jimmy Garrison (bass). Several of Coltrane's albums from the period are recognized as examples of modal jazz: Africa/Brass (1961),[9]Live! at the Village Vanguard (1962), Crescent (1964), A Love Supreme (1964),[9] and Meditations (1965). Coltrane's compositions from this period such as "India", "Chasin' the Trane", "Crescent", and "Impressions" have entered the jazz repertoire, along with his interpretations of standards like Richard Rodgers's "My Favorite Things", and the traditional "Greensleeves".

Well Tizol did the melody, and he said that, you know, he used to hear those unusual melodies, because in Puerto Rico where he studied, they were very poor and they couldn't afford too much music. So in order to make them get more practice and get varied compositions, they'd turn the music upside down. And the result, you get that modal sound that comes from most of the things Tizol's involved in.
