how do i make it play different notes of music?

Type MML on the console and press help button [?] on the keyboard. MML stands for Music Macro Language btw.

I show you one short example of MML. Could you refer to and try the following? ' National Anthem of USA BGMPLAY"@56L4[O4F8.D16>B-<DFB-2<D8.C16>B-DEF2F8.F16<D.C8>B-A2G8.A16B-B-FD>B-]"
