 | | Improvisation can be structured, with certain rules constraining the improvisation (for example, "make up a song about bicycles", "use these chord changes", and so on), or can have no such constraints (free improvisation). |
 | | A growing number of contemporary composers are requiring a greater degree of improvisation in their music, including Pauline Oliveros, Terry Riley, and Christian Wolff. |
 | | Improvisation is also performed as an art form itself in theatres around the world, sometimes with dramatic intent but more often in comedic form (the most famous is Chicago's The Second City). |
