The Hobby, Skill, and Career of Piano Tuning

Skeleton Ear Training Test - Level 3

In this test, the coincidental partials are partially filtered.
The beats are there but there is some of the rest of the piano sound added..

Tune C#4 so that each of the three intervals beats as SLOW - MEDIUM - FAST

Each time C#4 is changed, A3C#4 will play at the new speed.

Because of the way F3 was set in this test, each M3 must increase in speed.

In a real tuning, you might end up with FAST-MEDIUM-SLOW,
but if they change speed each pair by the same degree, or ratio,
then C#4 will be accurate.
