This is a game to practice building all sorts of triads with different parts of the bats. The mediant is the middle of the bat. The game includes all notes and enharmonics, along with blank pieces for double accidentals or missing pieces. It could be for Halloween, or could be used year round - bats are animals all the time! :)
This hard good comes with all 11 pages of pieces printed in color on cardstock and laminated. No sharp corners here! Ships for free!
