Find every C first

Look for any pair of black keys. The white key immediately to the left is C. Moving right gives D and E, followed by F before the group of three black keys.

From one C to the next C is an octave. The pitch is higher or lower, but the letter sequence repeats exactly.

Why prompts show A, S and D instead of C, D and E

A piano note name describes the sound; a computer letter describes the physical key to press. For example, pressing computer key A produces C3.

During guided practice, follow the computer letter first. Use note names later to understand the melody. They serve different purposes.

How black-key names work

A black key often has two enharmonic names. The black key right of C may be called C-sharp or D-flat. This site mainly uses sharp names in mappings.

At the beginning, simply understand that a black key sits between two white notes. You do not need every key signature at once.

FAQ

Frequently asked questions

Is middle C exactly at the physical center?

It is near the center, but the visual position varies with keyboard size. Use black-key groups to confirm it.
