My friends are wanting to create an app that would vizualise music in 3-dimensional but I cannot understand what they want to vizualise. Could someone help me with this? Does there exist this kind of apps and what are they called? What kind of properties are good to vizualise in music with many dimensions?

If you don't understand your question, we can't help you very much! ;). Welcome to Music Exchange! –  Cody Guldner Mar 15 '13 at 0:19
    
This question is so vague I have no idea how we could help you. Can you clarify things? Are you a musician, and do you understand musical concepts? –  Wheat Williams Mar 15 '13 at 13:26
    
@WheatWilliams "abstract" does not meean "vague". Please, see my comments in answers -- I think they are going to the right direction, good stuff. –  hhh Mar 15 '13 at 15:43

What do you mean by "dimensions"? How knowledgeable are you about music theory? About acoustics and the physics of sound? Any meaningful answers would be explained in those terms. –  Wheat Williams Mar 15 '13 at 15:52

Wikipedia has a list en.wikipedia.org/wiki/Music_visualization. I would also look into visualisers used in Winamp. Haven't searched through this myself so sorry I can't be more helpful—except to say yes, there do exist apps that have attempted this. –  isomorphismes Jan 17 at 14:31

The usual 2 dimensions are time and pitch. In standard notation, x is time, y is pitch.

A 3rd dimension could be velocity of note down event.

But there are plenty of other things you COULD put in like current root note of chord, chord type(major/minor/7th/etc), pan of the mix, volume of the mix, hold pedal, notes on ALL the other tracks beyond, say, the piano track you're playing, etc.

If you want to know what other dimensions could be, ask your friends who are giving you specs. If you're the developer and they're the spec guys, just realize that pulling good specs out of users can be pretty brutal :)

+1 that is useful, do you know whether anything like this is done already? There must be something around with some specific name. –  hhh Mar 15 '13 at 11:06
    
unfortunately, all my links are old:( There are quite a few apps out there, though. Most are just "interesting to watch", though. Not helpful for piano practice. There's my app pianocheetah.com/tutorial/screenshots.html scroll down to see pitch in x dir and note in color and time in y dir. The only non-dead link I've got is to some silly flash things: soundtoys.net/tags/soundtoys –  Stephen Hazel Mar 15 '13 at 15:55

I'm doing a course at the moment and there's some people talking about drawing with a piano, which maybe what your friends are discussing. If you want to search it out, it's a public google+ community called Learning Creative Learning and the post is about creative coding with processing.org. Obviously the computer screen is 2D but the illustration looks 3D
