The "Gift" of Math and Music
Looking for that special gift? Just in case you cannot find it from the stores mentioned on the Resource page, please consider the Piano Calculator.
Every key press plays a note...imagine the fun of doing calculations now! The dream: calculating square roots in the Key of G, or turning a special repeating fraction into a Bach Concerto.
It supposedly can be purchased from Rakuten, a Japanese distributing company, for about $10.
