1. Improvisation: Jazz musicians often improvise, or make up music on the spot, while they are playing. This is one of the things that makes jazz unique and exciting.
2. Syncopation: Jazz often uses syncopation, which is when the accents in the music don't land on the expected beats. This can create a feeling of tension and excitement.
3. Call and response: Jazz musicians often play call and response, where one musician plays a phrase and the others respond with a similar phrase. This can create a feeling of conversation between the musicians.
4. Blue notes: Jazz often uses blue notes, which are notes that are slightly flat or sharp compared to the notes in a traditional scale. This can create a feeling of sadness or longing.
5. Swing: Jazz often has a swing feel, which is a bouncy, rhythmic feeling. This is created by playing notes slightly ahead of or behind the beat.
6. Polyrhythms: Jazz often uses polyrhythms, which are two or more different rhythms played at the same time. This can create a feeling of complexity and interest.
7. Vocal techniques: Jazz vocalists often use a variety of vocal techniques, such as scat singing, growling, and falsetto. These techniques can help to create a more expressive and emotional performance.
