|Performous is a free game. This means that the source code is available to be studied, modified, and distributed. Most projects look for help with testing, documentation, graphics, etc., as well.|
The game is written in the C++ programming language and from version 0.3.0 onwards uses OpenGL for graphics.
The main game package does not include any songs, like a player does not include any music, but there are various liberally licensed songs available from the homepage.
The game scores you based on how well you hit the notes. The game helps you by showing what pitch you are singing so that you can correct your voice.

Performous is also packaged in e.g. Debian, Ubuntu and Gentoo.
