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 .

Hey 👋, I'm Seb and I'm creating muted.io
I need your help! If you have a few dollars to spare, I would be incredibly grateful if you could donate to support the development of muted.io. 🙏
I estimate that I would be able to fully support myself if only about 3% of the site's visitors made a one time $4 donation.
My ultimate goal is to be able to focus my time on creating more free musical tools, and your donation will go directly towards making that goal a reality. 🙌
- Seb, ✌️ + ❤️
