How Many Keys Are There on a Piano?

Did you know that:

  • Piano keyboards exist in many different sizes and with different numbers of keys.
  • A full sized regular piano keyboard has 88 keys.
  • Other electronic keyboards can have almost any number of keys.
  • When buying a piano or keyboard it is good to remember that many piano pieces are not playable on keyboards with fewer than 88 keys...!

Smaller keyboards with fewer keys may be used for playing chords, background harmonies or other sounds for example.

How Many Different Notes Are There?

In music of the western tradition, there are 12 different notes:

  • 7 are the Basic Notes, named after the first 7 letters in the alphabet; A, B, C, D, E, F, G. These are the white keys.
  • 5 are the Altered Notes, a semitone or half step higher or lower from the basic notes. These are the black keys.

On the piano keyboard this can be easily seen in the pattern of the white and black keys.

So the piano keyboard actually has only 12 different keys; 7 white keys and 5 black keys. The rest of the keys are just repeated with either higher or lower pitch.

White Keys and the Basic Notes

Here is a piano keyboard diagram with the note names of the white keys, or the basic notes:

Piano Keyboard with Notenames

You can see that the 7 basic notes are repeated over and over. But each time the pitch (how high or low the tone is) is sounding one octave higher (if you go to the right).

An octave is the distance, or interval, from one note or tone to the next with the same name, higher or lower.

You can also see that all keys have a black key between them except between E - F and B - C. All steps (the interval from one key to the next) that have a black key between them, are called whole steps.

Those that don’t, E-F and B-C, are smaller and called semitones or half steps.

There are also half steps between a black and the white key next to it, or reversed. And there are whole steps from one black key to the next with a white key between.

Black Key Patterns

See how the black keys are grouped in two’s and three’s, all over the keyboard?

This repeated pattern also makes it easier to find our way on the piano:

The black keys make it possible to play many more scales and melodies. They fill in the “gap” where there are whole steps, so to speak!

By playing all the keys one by one, both the white and the black keys next to each other, you can play a chromatic scale.

A chromatic scale is made from only half steps.

Naming the Black Keys - Accidentals

The black keys are named after the white; they are alterations of the white keys.

The black keys have two names. 

The name depends on from what white key it started from.

So how do you alter a white key? Easy, just use one of two music symbols; the sharp (#) and the flat (b).

These symbols, together with the natural sign are called accidentals (nope- no accident!). You will only see accidentals written in the sheet music.

If you just talk about a black key without reading any sheet music, it is OK to use any of the two names.

Let’s say you read the note C. If there is a sharp sign (#) in front of C you get to play the black key a half step higher (to the right) - Yay!


In the same way you can use the flat sign (b) to lower a note. Starting from D this time, and having a flat sign in front of that D, you play the black key a half step lower (to the left).

-Whoa, stop there! Db is the same key as C#???

Yes it is! The keys can have two names, depending on the accidentals. If they end up on the same key like this, they are called enharmonic (“one sounded”).

Piano Keys Layout

You can use sharp and flat signs on any note. So even an E can have a sharp sign… and where does it go? To F!

Since there is already only a half step between E and F - and a sharp sign raises the note a half step - there is only F, so E# and F are also enharmonic.
