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 piano 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...!

Helpful Tools

As you start learning the piano, you can also use a Piano Keyboard & Note Chart like this for placing behind the keys.

Or simply get these Keyboard Stickers with note names and stick on the keys, that you can easily remove later.

So, How Many Different Notes Are There?

Piano keys with names.

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

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

On the piano keyboard layout, this can be observed 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.

Piano Key Notes

Here is another 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 (A B C D E F G) are repeated over and over. But each time they repeat, the music pitch (how high or low the tone is) sounds one octave higher (if you play to the right on the keyboard).

An octave is the distance, or music 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) having a black key between them are called whole steps or tones. Those that don’t, E-F and B-C, are smaller and called semitones or half steps.

There are also half steps/semitones 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.

Look at this piano keyboard diagram where the black key groups are circled:

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 or semitones.

Naming the Black Keys - Accidentals

The black keys are named after the white right next to them. They are alterations of the white keys.

The black keys have two names. The name depends on what white key it started from, the one above or the one below.

So how do you alter a white key?

Easy, just use one of two music symbols; the sharp (♯) or the flat (♭). These symbols, together with the natural sign (♮), are called accidentals. (Nope- no accident!).

You will see accidentals written in the sheet music right before a note.

By the way: If you just mention 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 (♭) to lower a note.

Starting from D this time, and imagine having a flat sign in front of that D, you will then instead play the black key a half step lower (to the left):

-Whoa, stop there! D♭ 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”).

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

Since there is only a half step between E and F - and a sharp sign raises the note a half step - there is only F to go to. So E♯ and F are also enharmonic.

PS. If you read all this- perhaps you no longer need the piano keyboard diagram! :)
