Key signatures – Sharps and naming the major sharp key
Each of the key signatures that have sharps are called different major sharp keys.
Note: notice how C major has NO sharps and NO flats but C sharp major is the opposite and has all of them.
C Major = NO SHARPS
C Sharp Major = ALL THE SHARPS
If in an exam you are shown sheet music and asked what key signature it is in, you can answer by following this rule:
LOOK AT THE LAST SHARP LISTED AND GO UP ONE ALPHABET LETTER
If the last sharp listed is an:
A then it's B major
B then it's C sharp major (must include the word sharp)
C then it's D major
D then it's E major
E then it's F sharp major (must include the word sharp)
F then it's G major
G then it's A major
The G has to go to A because it is the next key up in music.
