フリー・ジャズ
In Brazil, a new style of music called bossa nova evolved in the late 1950s. The free jazz movement, coming to prominence in the late 1950s, spawned very few standards. Free jazz's unorthodox structures and performance techniques are not as amenable to transcription as other jazz styles. However, "Lonely Woman" (1959) a blues by saxophonist Ornette Coleman, is perhaps the closest thing to a standard in free jazz, having been recorded by dozens of notable performers.
