DSU Lesson #2 – Train Your Ear to Hear Different Out of Tune DSU

Try out these buttons and hear what a DSU sounds like when it is out of tune by the cents listed:

After you think you have a good idea what each sounds like, take this test:

Click the [Random DSU] button below.

One of the out of tune DSU’s above will play.

You will get one chance to choose the right out of tune DSU from the list below

that matches the sound of the random DSU.

Try to guess the right DSU without checking the sound of the DSU’s above. That’s cheating! ?

0.0 cents

0.2 cents

0.3 cents

0.5 cents

0.7 cents

0.8 cents

1.0 cents

1.2 cents

The Go APE method teaches DSU tuning as well as many other

advanced techniques that are easy to learn, and together help you

produce aural tunings that are more Accurate, Precise, and Efficient!
