Free improvisation

Free improvisation or free music is improvised music without any general rules, instead following the intuition of its performers. The term can refer to both a technique—employed by any musician in any genre—and as a recognizable genre of experimental music in its own right.

Free improvisation

Free improvisation, as a genre of music, developed primarily in the U.K. as well as the U.S. and Europe in the mid to late 1960s, largely as an outgrowth of free jazz and contemporary classical music. Exponents of free improvised music include saxophonists Evan Parker, Anthony Braxton, Peter Brötzmann, and John Zorn, composer Pauline Oliveros, trombonist George E. Lewis, guitarists Derek Bailey, Henry Kaiser and Fred Frith, bassists Damon Smith and Jair-Rohm Parker Wells and the improvising groups Spontaneous Music Ensemble and AMM.

Characteristics[edit]

In the context of music theory, free improvisation denotes the shift from a focus on harmony and structure to other dimensions of music, such as timbre, texture, melodic intervals, rhythm and spontaneous musical interactions between performers. This can give free improvised music abstract and nondescript qualities.[1] Although individual performers may choose to play in a certain style or key, or at certain tempos, conventions such as song structures are highly uncommon; more emphasis is generally placed on the mood of the music, or on performative gestures, than on preset forms of melody, harmony or rhythm. These elements are improvised at will as the music progresses, and performers will often intuitively react to each other based on the elements of their performance.


English guitarist Derek Bailey described free improvisation as "playing without memory".[2] In his book Improvisation, Bailey wrote that free improvisation "has no stylistic or idiomatic commitment. It has no prescribed idiomatic sound. The characteristics of freely improvised music are established only by the sonic musical identity of the person or persons playing it."[3]


Free music performers, coming from a disparate variety of backgrounds, often engage musically with other genres. For example, Italian composer Ennio Morricone was a member of the free improvisation group Nuova Consonanza. Anthony Braxton has written opera, and John Zorn has written acclaimed orchestral pieces.

Free improvisation on the radio[edit]

The London-based independent radio station Resonance 104.4FM, founded by the London Musicians Collective, frequently broadcasts experimental and free improvised performance works. WNUR 89.3 FM ("Chicago's Sound Experiment") is another source for free improvised music on the radio. Taran's Free Jazz Hour broadcast on Radio-G 101.5 FM, Angers and Euradio 101.3 FM, Nantes is entirely dedicated to free jazz and other freely improvised music. A l'improviste,[15]
