For everyone

Using Tim0lmazan's 'game music kit', you can make music with blocks which don't have any scripts inside them! You might need to copy the sheet block a little to make longer songs. Also, the sound pitch depends on the Z position.

For experienced creators

You can use a modulo and just detect the frame. Use a number. You need a beat var, unless using Current Frame. Then, do this math: ^(2,÷(any, 12))

Now choose to play a sound when the event is detected!

Don't want to make but want music?

Find a editable working music on Fancade game search on the Fancade app. But if you think the music is too bad for your game, then try to modify it.
