The owner of Piano Tuning & Repair is also the inventor of A-440 Perfect Pitch - The Music Education Board Game!
It is designed as a music board game that teaches perfect pitch.
The piano strings representing the tone A above middle C should be set to vibrate when struck at 440 times per second which results in the true pitch of A.
The other tones of the piano are tuned in ratio to the true pitch, hence the name of the game!.
