Piano Key Chart

At the beginning of each clef is the key signature, or piano key chart. The key signature can have sharps or flats. In this piano lesson, you learn to find a key.

Some keys are denoted by the number of notes that have sharps. Other keys are denoted by the number of notes with flats.

There are 12 keys per octave. C D E F G A B seven white notes C# D# F# G# A# five black notes

You can call the five black notes Db Eb Gb Ab Bb

In any of these keys they may be major keys or minor keys.

You can tell what key the song is in by the number of sharps for some keys and by the number of flats for other keys.

THE KEY SIGNATURES WITH SHARPS

The key of G major has one sharp F#. The key of D major has two sharps F# C#. The key of A major has three sharps F# C# G#. The key of E major has four sharps F# C# G# D#. The key of B major has five sharps F# C# G# D# A#.

Look at the last sharp in the key signature and the key will be a half step up from it.

F# go up a half step to G the key is G. C# go up a half step to D the key is D. D# go up a half step to E the key is E. A# go up a half step to B the key is B. G# go up a half step to A the key is A.

Sharps increase by a fifth interval as in from F# to C#. Then C# goes to G#. Then G# goes to D#. Then D# goes to A#.
