All the Major Key Signatures in Treble & Bass Clef.
All Major Key Signatures written on the Treble & Bass Clefs
Here are all the major key signatures as they are written on the Treble and Bass Clefs. The top row shows the flat keys and the bottom row shows the sharp keys.
First thing to notice, as we move to the right, every key signature adds one flat or sharp. Looking at the first row, the flat keys, the C Major has no sharps or flats. F Major has one flat. Bb Major has two flats. Eb Major has three flats and so on.
Same applies to the sharp keys. C Major has no sharps or flats. G Major has one sharp. D Major has two sharps. A Major has three sharps and so on.
There's uniformity in how Sharps and Flats are added. The first flat added to a key signature is Bb, the second flat added to a key signature is Eb. Bb is always the first flat added in every major key signature that has one or more flats. Eb is always the second flat added in every major key signature that has two or more flats. Ab is always the third, Db is always the fourth and so on.
The same is true with sharp keys. The first sharp added is F#, the second sharp added is C#. F# is always the first sharp added to any key signature with one or more sharps. C# is always the second sharp added. G# is always the third and so on.
There is a specific order in which flats and sharps are added to major key signatures. The order of flats are Bb, Eb, Ab, Db, Gb, Cb, Fb. The order of sharps are F#, C#, G#, D#, A#, E#, B#.
Three (3) of the key signatures are Enharmonic key signatures.
