App Description

Why is that wolf lurking in the clavichord? Because it skulks along with the meantone tuning system, used by most keyboards of the 16th and 17th centuries.

What is quarter-comma meantone temperament and how does it work? Which problem does it solve, and which problem does it create? MeanTones answers your questions with some math, some music, and lots of fun. Choose a note and an interval to play on the Piano, or switch to the Cheesy Organ if you’re brave. Either way, you’ll hear the interval in meantone, and you’ll see a complete chart of the numbers comparing it to the same interval in equal temperament. The Background Information explains the meantone tuning system in detail, and the Timeline puts it all in perspective.

Press “Play Game” to put your knowledge to the test. You see and hear an interval, and quick — is it a wolf? If you’re right, you add a new layer of bricks to your house. But if you’re wrong, the wolf will huff and puff and blow your house down!
