the names of the white-key pitches (also called the natural
pitches)
how to find them on the keyboard
The names of the white-key pitches are the letters A through G:
A B C D E F G
These 7 letters are reused over and over as we go up/down the pitch
range. So, the white keys on a piano are named like this:
Different pitches with the same letter-name sound like higher or
lower versions of the same pitch. You should hear this:
Click 3 different A's above.
Then, click 3 different B's.
See if you can hear how the 3 A's sound like "low or high versions of
the same pitch", and the same for the 3 B's.
Finding the Pitches on the Keyboard
Let's start with letter A. Here's a keyboard with just the A's
labeled:
You can find any A (or any other letter) from its place in the
pattern of black keys. To find any A:
Find one of the groups of three (not two) black keys.
In those three black keys, the white key just to the right of the
middle black key is an A.
Next, let's add the B's to the keyboard:
There are two ways to find any B:
Using the black keys.B is "just to the right of the 3 black
keys".
Using another letter that you already know. For example, if you
know where A is, then you can say "A, B" while you touch A,
then B.
Finally, here's the keyboard with all the letters labeled again:
By looking at this keyboard, we can come up with a "black-key position
rule" to find any letter:
A is "to the right of the middle black key".
B is "to the right of the 3 black keys".
C is "to the left of the 2 black keys".
D is "between the 2 black keys".
E is "to the right of the 2 black keys".
F is "to the left of the 3 black keys".
G is "to the left of the middle black key".
Are you wondering:
Why we repeat the same letters for higher pitches (a more detailed
reason)? The answer starts with
Lesson 50: Pitch & Frequency.
Why we use seven different letters, A-B-C-D-E-F-G (instead of, say,
six or eight letters)? A simple answer is, because we need seven letters
for the seven degrees of a major scale. To understand that,

Lesson 17: Major Scale 1-8.
