lady poker face acoustic

Can someone explain exactly what acoustic music is that?

I was listening to an acoustic version of Poker Face Lady GaGa, and it sounds so much better than original. I'm looking online for the acoustic definition, but did not really find a clear definition. So all the music genius than to explain what acoustic music is a clear definition of who is a musician could understand.

acoustic music is usually, which is not electronic instruments. It generally uses instruments such as acoustic guitar and piano:) 2 good examples:) Http: / / www.youtube.com/watch?v=UVHk4dc7yaE http://www.youtube.com/watch?v=aHTe6ed8xfU
