"What about a tower defense game where you create your own song that is played by the towers as creeps flow through?"
I'm a programmer and game designer, and Music Tower Defense is a game that I'd really like to make. This thread is for the composers I'm working with to discuss ideas for how it might work.
So far, composers TrierMusic, Exilement, LJCoffee, and possibly MackerelSalad have all expressed interest in working with me on this project. I don't want to get a ton of requests to join the project, but if you really think you would be a valuable contribution to the team, start by participating in this discussion and if you have helpful ideas we'll probably want to include you.
About the Music Tower Defense
I came up with the concept while playing Bloons Tower Defense. The polyrhythm created by towers firing at different rates made me wonder what it would be like if a tower defense game explicitly tried to weave the sounds of the game into a coherent musical experience. Try playing the game, and listen with that in mind.
Out of the ideas offered to me by my composers so far, a few are easy to explain here. Exilement thought that the game Electroplankton would be a good role model for the interactive, more or less random generated music. Each tower would play a randomly selected sound when it fires, and each creep would play a randomly selected sound when it gets hit, or something along those lines. Exilement suggested that Ambient would be a good genre of music to use for this approach.
As the programmer on this project, I can say that it is definitely possible to use more complicated rules to control which sounds are played. A lot of pretty cool stuff should be possible. Though starting simple, where each action in the game corresponds to a direct change in the music, would be a good idea at this point. For an example of some fairly complex interactive music, try my old game Braids. I've also done a simpler experiment with interactive glitch music in my recent game _dRive.
We were thinking that each composer would design interactive music of a different genre, each of which would have its own unique set of towers and creeps and upgrades, as well as its own graphical style. Each genre would basically be a different game mode, which the players could choose from. This should allow for a maximum of creative control by the composers.
As a final point of inspiration, listen to the song Assembly Warfare by Suspended-3rd-Chord. I think this song could be almost perfect for use in Music Tower Defense, and Suspended-3rd-Chord is more than welcome to be a part of this project if he wants to.
Let us discuss, and blaze new pathways into the unexplored wilds of interactive music design!
