Piano Keyboard Layout
The Keyboard's Pattern
The piano keyboard might look complicated, but it’s built on a simple, repeating pattern. Look at the black keys. You’ll see they are arranged in groups of two and three, separated by white keys. This pattern of two black keys, then three black keys, runs the entire length of the piano.
This pattern is the key to finding your way around. Once you can spot the groups of two and three, you'll never be lost.
Music uses the first seven letters of the alphabet for note names: A, B, C, D, E, F, and G. After G, the cycle starts over again at A. Every white key has one of these letter names.
To find any note, start by locating the note C. Find any group of two black keys. The white key immediately to the left of that group is always a C. Try finding all the C's on your keyboard.
Naming the Notes
Once you've found C, you can name all the other white keys by simply moving up the alphabet. The white key to the right of C is D, the next is E, then F, G, A, and B. After B, you’ll find the next C, located just to the left of another group of two black keys.
Notice there are no black keys between E and F, or between B and C. This is an important feature of the keyboard layout.
What is an Octave?
The distance between one C and the next C is called an octave. An octave contains all seven unique notes (C, D, E, F, G, A, B) plus the five black keys. If you play a C, and then play the next C up on the keyboard, you are playing the same note, but one is at a higher pitch than the other.
The entire keyboard is made of repeating octaves. Moving to the right on the piano means you are going up in pitch—the notes sound higher. Moving to the left means you are going down in pitch, and the notes sound lower.
A full-size piano has 88 keys. The C key closest to the middle of the keyboard is called Middle C. It’s a common reference point for finding your position.
Find Middle C. It's the C located nearest to the piano's brand name or the center of the keyboard.
Now that you can identify the keys and understand how octaves work, let's check your knowledge.

How do you locate the note 'C' on a piano?
Getting comfortable with the layout is the first big step. Spend some time just finding the notes and saying their names out loud.
