Worksheet for identifying major key signatures in music.

To find the name of each major key signature, we look at the sharps (#) or flats (b) on the staff. Here is the step-by-step logic for each one:

Left Column (Sharps):
1. No sharps or flats: This is always C Major.
2. One sharp (F#): The rule for sharps is to take the last sharp and go up one half-step. F# goes up to G. So, this is G Major.
3. Two sharps (F#, C#): The last sharp is C#. Going up one half-step from C# gives us D. So, this is D Major.
4. Three sharps (F#, C#, G#): The last sharp is G#. Going up one half-step from G# gives us A. So, this is A Major.
5. Four sharps (F#, C#, G#, D#): The last sharp is D#. Going up one half-step from D# gives us E. So, this is E Major.
6. Five sharps (F#, C#, G#, D#, A#): The last sharp is A#. Going up one half-step from A# gives us B. So, this is B Major.
7. Six sharps (F#, C#, G#, D#, A#, E#): The last sharp is E#. Going up one half-step from E# gives us F#. So, this is F# Major.
8. Seven sharps (all sharps): The last sharp is B#. Going up one half-step from B# gives us C#. So, this is C# Major.

Right Column (Flats):
*Note: For flats (except for F Major), the name of the key is simply the second-to-last flat.*

9. One flat (Bb): There is no "second-to-last" flat here, so we just memorize this one. One flat is always F Major.
10. Two flats (Bb, Eb): The second-to-last flat is Bb. So, this is Bb Major.
11. Three flats (Bb, Eb, Ab): The second-to-last flat is Eb. So, this is Eb Major.
12. Four flats (Bb, Eb, Ab, Db): The second-to-last flat is Ab. So, this is Ab Major.
13. Five flats (Bb, Eb, Ab, Db, Gb): The second-to-last flat is Db. So, this is Db Major.
14. Six flats (Bb, Eb, Ab, Db, Gb, Cb): The second-to-last flat is Gb. So, this is Gb Major.
15. Seven flats (all flats): The second-to-last flat is Cb. So, this is Cb Major.
