My school is having a talent show on the second month we go back to school. im asking now cuz i doan make fast decisions. so should i sing this is me while playing piano, or just play the piano?
If you have a good voice and can do both at the same time, do so, that is if your singing doesn't make you play worse, othwerwise just play the piano.
Why don't you try each and ask someone to take you to the video, then you can watch the videos and decide yourself.
