Free jazz

Free jazz is an approach to jazz that developed in the 1960s when musicians attempted to change or break down jazz conventions, such as regular tempos, tones, and chord changes. Musicians during this period believed that the bebop, hard bop, and modal jazz that had been played before them was too limiting. They became preoccupied with creating something new. Free jazz has often been combined with or substituted for the term "avant-garde jazz". Europeans tend to favor the term "free improvisation". Others have used "modern jazz", "creative music", and "art music". The ambiguity of free jazz presents problems of definition. Although it is usually played by small groups or individuals, free jazz big bands have existed. Although musicians and critics claim it is innovative and forward looking, it draws on early styles of jazz and has been described as an attempt to return to primitive, often religious, roots. Although jazz is an American invention, free jazz musicians drew heavily from world music and ethnic music traditions from around the world. Sometimes they played foreign instruments, unusual instruments, or invented their own. They emphasized emotional intensity and sound for its own sake.
