Key Signatures

The key signature is located at the beginning of a composition (after the clef) and each stave.   It is made of sharps or flats and identifies the key of the composition.  "The key" of the composition tells you what note name is "Do".  The sharps or flats in a key signature apply to every pitch of that note name in every octave.

Too identify sharp key signatures:  1) Identify the note name of the last sharp in the key signature  2) Go up a half-step from that sharp to find the major key

--If the last sharp is C# the key is D

--note: if the last sharp is E#  the key is F# or if the last sharp is B# the key is C# because those notes are already sharp in the key signature.

         Key of GThis is the key of G because F# is the last sharp in the key signature. G is half step above F#.

Key of E
This is the key of E because E is half step above D#, which is the last sharp in the key signature. It is not the key of E# because there is no E# in this key signature.
Key of C#
This is the key of C#. Why? The last sharp in this key signature is B#. Half step above that is C#.  The quick way to determine this is to look at the sharps already in the key signature. In this case, there is already a C# in the key signature, so this key is the key of C#.

The following exercise is to practice sharp key signatures:
