What does the musical term improvised mean?

In music, the term "improvised" means to spontaneously create and perform music without prior preparation or written notation. It involves creating on-the-spot melodies, harmonies, and rhythmic patterns in real time, often as part of a live performance. Improvisation is commonly associated with jazz, blues, and certain world music styles, where musicians have significant freedom to creatively express themselves while adhering to the overall musical structure.

Improvised music requires a high level of musicianship, quick thinking, and the ability to listen attentively to fellow performers. It encourages individual interpretation and encourages musicians to draw from their skills, techniques, and musical knowledge to produce unique and dynamic musical experiences. Improvisation adds an element of unpredictability and spontaneity to performances, creating a sense of immediacy and personal connection between musicians and their audience.
