Qbasic – Background Wave Player

I am trying to make a program in Quick Basic where I have the soundblaster play music in the background while the main is going in the foreground. I want this so that the music sounds nice and not choppy. I dont want a file that is so long and hard to understand. I know there are files called dmaplay.bas and so on, but they contain too much information and I am unable to figure out how they do it. so where is a short program that can play sound in the background? Remember, it must come from thesound blaster, not from the speaker. The more explanation you give, the better chances of success in getting the points you have.
