Key Signature Chart: Major & Minor Key Signatures

🎼 A key signature is the sharp or flat symbols that we put next to a clef like the treble or bass clef to indicate which note(s) on the staff should be sharp or which note(s) should be flat for a piece of music or a section of a piece of music.

Since each major scale (or its relative minor scale counterpart) has a different number of sharpened or flattened note in the scale, a key signature is therefore useful to tell us in which key we are in for a piece of music. We just look at the key signature on the staff and know right away which major or minor key has that key signature.

This page gives you a reference to the major and minor key signatures. You may also want to check out the Circle of Fifths, which is a helpful tool to help remember how many sharps or flats a key has.

→ I've also created a little game to help you practice your key signature identification .
