harmony-based gameplay

so i've noticed that with its rhythm-based gameplay, audiosurf seems tilted towards fast-paced songs.  slower songs just don't offer much of a challenge.

but what if there were a scoring system that allowed you to match blocks that corresponded to notes and chords? for example, there'd be a bonus for matching 3 blocks in a set that correspond to notes in a chord.  i don't really know enough about music theory to flesh out this idea, but it's something that i'd like to see implemented.

Well if you take time to notice, all of the blocks that come up on the track when you play Audiosurf are already in rhythm with the song. One set of blocks for percussion, the other for vocals, another for guitars and bass, etc. If you pay closer attention you will also find strings of blocks in tune with a quick succession of notes like you explained, but getting these do not earn you any extra points for grabbing them.

I don't think audiosurf is meant to be an especially challenging game for the musically inclined, I believe that the best challenge is to play an actual instrument and accomplish something worthwhile. Audiosurf is just there to give you some eye candy and a relaxing little game when you just want to listen to music but find it silly to just sit there and listen. It does it well but it's a novetly and gets old quick.
