Aclassic kind of total art, was pioneered by the american artist allan kaprow (1927–2006). kaprow, who coined the name for this conceptual genre, called it "a performance that occurs in a given time and space."

they most likely have a instrumental version. just look it up on google.

the answer is counterpoint.

counterpoint definition: "the art or technique of playing a melody or melodies in conjunction with another, according to fixed rules."

counterpoint is present in a lot of baroque music- such as bach (notably his wtc prelude and fugues) and scarlatti, but can also be found in music by mozart, beethoven. it can even be found in music as modern as john williams!
