Improvisational music is a form of music created spontaneously, without pre-composed notes or arrangements. Musicians often rely on their intuition, creativity, and understanding of musical theory to produce sounds in real-time. This style can be found in various genres, including jazz, blues, and classical. In improvisational music, performers may interact with each other, responding to one another's ideas and emotions. This collaborative aspect allows for unique and unpredictable performances, making each session distinct. Notable improvisational musicians include Miles Davis and John Coltrane, who are celebrated for their innovative approaches to spontaneous music-making.
