Please answer the following question: Information: - Modal jazz is jazz that uses musical modes rather than chord progressions as a harmonic framework. Originating in the late 1950s and 1960s, modal jazz is epitomized by Miles Davis's 1958 composition "Milestones", 1959 album "Kind of Blue", and John Coltrane's classic quartet from 196064. Other important performers include Woody Shaw, Bill Evans, Herbie Hancock, Wayne Shorter, McCoy Tyner, Larry Young, Pharoah Sanders, Joe Henderson, Chick Corea and Bobby Hutcherson. Though the term comes from the use of the pitches of particular modes (or scales) in the creation of solos, modal jazz compositions or accompaniments may only or additionally make use of the following techniques: - Johannes "Hannes" Bauer (22 July 1954 6 May 2016) was a German trombonist of improvised music and free jazz. He was the brother of the trombonist Conny Bauer. - Konrad "Conny" Bauer (born 4 July 1943 in Halle, Saxony-Anhalt, Germany) is a free jazz trombonist. He is the brother of the trombonist Hannes Bauer. - Free jazz is an approach to jazz music that was first developed in the 1950s and 1960s as musicians attempted to alter, extend, or break down jazz convention, often by discarding fixed chord changes or tempos. Though the music of free jazz composers varied widely, a common feature was dissatisfaction with the limitations of bebop, hard bop, and modal jazz that had developed in the 1940s and 1950s. Often described as avant-garde, free jazz has also been described as an attempt to return jazz to its primitive, often religious, roots and emphasis on collective improvisation. - Johannes '' Hannes '' Bauer ( born July 22 , 1954 in Halle ( Saale ) ) is a trombonist of improvised music and free jazz from Germany .
