Introduction: CD+G: CDG (or CD+G) is an audio CD format with graphics/pictures. You`ll be able to see the pictures (and lyrics) when you use a special CD+G player that is hooked up to your television. If your CD player doesn`t support CD+G, don`t worry it will still work, you will just get sound.

Demonstration Vocals: The most popular method used for demonstration tracks is to record each song twice. The first version of the song has the lead singer (this is sometimes called a demonstration track), and the second version of the song is just the instrumental part. The other common method is to use a "split-track" format - the lead vocal will play back from one speaker on your stereo, and the instrumental parts will play back on the other speaker. You can control the balance between the two tracks by adjusting the balance control on your stereo.

Background Vocals: When a song has backup singers that sing along with the lead vocalist, the parts that the backup singers sing are called "background vocals". The intention of a Karaoke CD is to sound as close to the original as possible. When there are background vocals on an original artist`s recording, those background vocal parts are almost always (but not 100 percent of the time) reproduced in the karaoke version of a song.
