Musical improvisation is the spontaneous creation of music without premeditation or written notation. It involves musicians using their skills, creativity, and intuition to produce music in real-time, often responding to the moment and to other musicians. This can occur in various musical genres, including jazz, classical, rock, and folk, and often involves a deep understanding of musical theory, harmony, rhythm, and a strong sense of musical dialogue. Improvisation allows for personal expression and can result in unique and original performances each time it occurs.
