Posture
Posture is an important part of singing effectively. A person's vocal control can be hampered by poor posture. The same posture tips used by singers work for "SingStar Pop" players. Keep your back and shoulders straight. This will create a direct path between your lungs and vocal chords. If possible, position your TV so you can see the screen without looking down. You want to avoid bending your neck to see the screen. It is slightly easier to be in the correct posture while standing, but playing while sitting works if the proper posture is maintained.
Listen to the Songs
It is almost impossible to get a good score on a song if you have never heard it before. Listening to songs from "SingStar Pop," even without singing, can help improve your performance. Singing in the correct pitch and rhythm will become much easier the more you listen to the song. This is not a substitute for developing the proper singing skills to perform the song, but will make it easier to apply your existing singing skills to a particular song.
Vocal Volume
The singer on the tracks of "SingStar Pop" is the person you are attempting to match. For this reason, that vocal track is the correct way to perform the song for a high score. Overriding the actual vocal track can make the game slightly more difficult. It is faster to adjust your pitch to the vocal track than to try to visually match the pitch on the visual indicator. With practice, matching pitch in this manner is also easier. Press the "L2" button on the controller to turn down your vocals. This will allow you to more clearly hear the original vocal track for the song.
Words Do Not Matter
Some players get tripped if they forget the correct words for a song. Singing the correct words is not important for getting a high score in "SingStar Pop." The game is only reading the pitch, rhythm and duration of the notes being sung, not the words. Repeat the last word you remember if you forget the lyrics. You will get more points for singing the wrong word at the right time than the right word a fraction of a second late.
