Patent number: 8987572Abstract: A system and method for teaching a user to discriminate and match musical pitch is disclosed. A pitch module generates a first melodic sequence for a user. The pitch module generates at least two symbolically depicted sequences including a first symbolic sequence that represents a pitch frequency that, when played, matches the first melodic sequence. A tracking module receives a selection of the first symbolic sequence and advances to a next level in response to receiving the selection of the first symbolic sequence.Type: GrantFiled: December 28, 2012Date of Patent: March 24, 2015Assignee: Generategy LLCInventors: Hirofumi Shimizu, Paul T.
