I’ve been trying out this music notation program called MuseScore. It can do some pretty awesome stuff, like mega-glissandos as shown below:
They are pretty crazy aren’t they?
I DARE YOU to try them out. See how much it hurts your hand. You can also access a PDF version here: crazy glissando
Listen to a recording of these played by a professional (NOT): http://theoks.net/~onekopaka/mwtrunk/images/6/69/Crazy_glissando.ogg. Oh, and if that link doesn’t work because you’re using a crappy browser, then head on over to http://theoks.net/~onekopaka/wiki/File:Crazy_glissando.ogg.
(Well actually, some of the notes are below the range of a standard piano so good luck!)
UPDATE: Added a nice coda at the end. Good luck with that!
