Music theory games for the NDS?

Dear muso's and good people of the romulation forum;I recently downloaded Rhythm and Notes for the NDS, and i was wondering if there were any more of these sorts of games available.thanks in advance

music games?electroplankton, elite beat agents for a start.

Try Protein (homebrew) etc. for some or that game starting with D. Although Protein is more of a music making remixer etc.
