Frequency (video game)
2001 video game on Playstation 2

Frequency (usually stylized as FreQuency) is a rhythm video game developed by Harmonix and published by Sony Computer Entertainment for the PlayStation 2. It was the first game to be developed by Harmonix. A sequel, Amplitude, was released in 2003.
Gameplay
In the game, a player portrays a virtual avatar called a "FreQ", and travels down an octagonal tunnel, with each wall containing a musical track. These tracks contain sequences of notes. As the player hits buttons corresponding to the note placement on the track, the "sonic energy" from within is released and the music plays. If the player plays two measures of the track without any errors, the track is "captured" and the music plays automatically until the next pre-determined section of the song. All songs featured in the game are edited for ease of play.
Some tracks are bonus tracks and only open up when all notes are played, allowing the user to pick up "freestyle" points. Powerups are available which allow the immediate capturing of the track or the doubling of points.

Why this record matters
