Description:

Performous - new Sing Screen using themed lyrics.

Performous is a free cross-platform clone of the Playstation 2
game Singstar.

While Performous might be classified as a karaoke program, it is
actually much more than that. Instead of just displaying the lyrics,
notes are also displayed and the performance is scored based on how
well you actually hit the notes. Unlike in many other games in this
genre, you will also see the pitch that you are singing, so that you
can see what you are doing wrong and easily (well, everything is
relative) correct your pitch.

Most of the songs available also contain the original vocals and actual
karaoke versions are rare.

Features
* Should work on almost any platform
* Very accurate singing pitch detection
* OpenGL-based graphics rendering
* Music videos as backgrounds
* Free software, licensed under GNU GPL version 2 or later
