Jam Session is an early music and rhythm game program for Macintosh computers. Designed in 1989, Jam Session allowed users to play along with famous songs. It was created around the same time as the idea of "music sampling" was coming into play and was the first electronic music game to provide actual licensed songs for the user to enjoy. The game assumed little to no musical knowledge on the part of its players and did not use a scoring system. Instead, users could tap along with the songs using any key they wished. Elements from current games like Guitar Hero, where the users tap along to the beat using colored frets, can be traced back to this early game.
