Jazz is one of the most popular music genres. It is often found in venues frequented by the wealthy. It was created from a combination of ragtime and blues. The most characteristic thing about jazz is that it cannot be defined in any way so that the definition is clear.
Jazz tunes are never completed, most notes and chords are pure intuition and improvisation of the musicians. These pieces are usually played to maintain the character of the place. It is most often played in restaurants or exclusive bars.
