Jazz improvisation is an important aspect of the genre. Jazz Improvisation is the process of spontaneously creating fresh melodies over the continuously repeating cycle of chord changes of a tune. Getting comfortable with the rhythmic concept of swing is critical to developing an improvisation that swings. The ability for performers to create musical phrases that agree with the harmonic structure of the chart is a challenging and gratifying experience. Developing a good sense of rhythm will help in developing melodic improvisation.
