Unison Lesson: Hear an Out-of-Tune Unison

Unison Lesson: Hear an Out-of-Tune Unison

As seen in What Are In-Tune Unisons,
when a unison is out of tune, the higher partials beat.

Click the [Out of Tune Unison] button below
to listen to an out of tune unison.

You may be able to hear some beating,
but can you hear each of the higher partials beating,
at a different speed, at will?

That is one of the most important skills of a good aural tuner.

That is what you HAVE to learn to do
if you want to learn how to tune a piano by ear.

Click each of the [Partial #] buttons below
to hear a filtered recording of the out of tune unison above,
with the first eight partials filtered out.

Then click the [Out of Tune Unison] button above,
and try to focus your ear on specific beating partials.

EXERCISE:

Click the [Partial 5] button below.

Listen to the frequency and speed of that specific beat,
then click the [Out-of-Tune Unison] button below and
try to hear that same beating partial.
within the full sound of the out-of-tune unison.

Do that with all the partials.

You should be able to clearly discern
the first five partials within the out of tune unison.
