how to make songs instrumental i been singing a song in class and when teacher heard she said that on the mothers day you have to sing it i said ok if i find the instrumental i really need it can anyone teach how to make a song insturmental?

You can find the song's karaoke in GOOGLE or YouTube.
Either way, use Virtual DJ!
But using Virtual DJ, the voice of the song can also heard a bit. So, better try searching it.

Like what tamerzz said.
Just search an instrumental version of the song.
Then download it (I will not recommend you any Legal Programs to downloading it xD)
And then. Record a video/recording of you singing(make sure its clear audio) and then go to a video making program and put the instrumental song over the video/recording.
And if the video is too loud, then make sure your recording is heard more clearly than the instrumental.
Sorry for the late response, but im pretty sure somebody else will need the information!
