1. how is jazz music similar to classical music? how is it different?

Jazz music and classical music both have differences as well as similarities too. Here are the similarities and differences between the two:
1. Rhythm - The most common similarity between the two is that they both use regular rhythm or a musical beat. However, classical music has a more steady rhythm.
2. Instrumentation - Some musical instruments are common in both such as the saxophone. But other instruments made a crossover from classical to jazz which are the flute, clarinet and trumpet. Conversely, some jazz instruments are now associated with classical music.
3. Improvisation - Improvisation makes each kind of music distinct. In classical music, performers are expected to play with a conductor; whereas, in jazz music, it places prestige on the individual performer and improviser.
