Baroque was the dominant style of music in the Western world from roughly 1600-1750. This genre created the concept of tonality and system of music theory that we still use and study today. The main characteristic that separates Baroque music from the other Classical genres is its ornamentation. Baroque music is very complex with constantly changing and evolving melodies as well as multiple layers of independent musical lines. The most common and famous musical form in Baroque music is the fugue. Fugues are instrumental pieces, typically played for organ or harpsichord, with 2-5 melodic lines that are played simultaneously.
