Identifying and Writing Key Signatures

Here are video reviews about identifying and writing key signatures.  These will be helpful in completing the homework for Monday 2/25.

Identifying key signatures with sharps (remember that the tonic is a minor second up from the last sharp):

Identifying key signatures with flats (the tonic is the next to last, or penultimate, flat in the key signature):

Writing key signatures with flats (write flats until you go one past the name of the key):

Writing key signatures with sharps (determine the sharp note that is a minor second below the name of the key):

Finally, remember that:

• In C major, all the notes are natural.  
• F major has one flat.
• Every other key named for a natural note (i.e., D, E, G, A, and B) has a sharp or sharps in it.
• Except for F (one flat) every key with flats in the key signature is has a flat in its name (B-flat, C-flat, D-flat, etc.)
