My Best program ever!

[WeekendLazyness]

Well, not really.
Guess what language it is.

CLS
PRINT "Starting from the bottom, we go up..."
PLAY "o0c8d8e8f8g8a8b8>c8d8e8f8g8a8b8>c8d8e8f8g8a8b8>c8d8e8f8g8a8b8>c8d8e8f8g8a8b8>c8d8e8f8g8a8b8>c8d8e8f8g8a8b8"
PRINT "And then down again...."
PLAY "o6b8a8g8f8e8d8c8<b8a8g8f8e8d8c8<b8a8g8f8e8d8c8<b8a8g8f8e8d8c8<b8a8g8f8e8d8c8<b8a8g8f8e8d8c8<b8a8g8f8e8d8c4"

I'm tempted to say it's BASIC, but I'm not 100% sure.

[BSTRhino]

Yes, that reminds me of my good old QBasic days...

It plays scales up and down, doesn't it?

[WeekendLazyness]

You got it!
