How do you notate quarter tones?
To notate a quarter tone scale requires only four additional accidentals: quarter sharp, three-quarter sharp, quarter flat and three quarter flat.
How do you identify key signatures?
To find the name of a key signature with sharps, look at the sharp farthest to the right. The key signature is the note a half step above that last sharp. Key signatures can specify major or minor keys. To determine the name of a minor key, find the name of the key in major and then count backwards three half steps.
What is the rule for key signatures?
Key Signature Rules
There is only one major scale for every key signature. Major scales use either flats or sharps but never mix the two. The highest number of sharps and flats you can have in a scale is 7. The order of sharps and flats follows a specific order and that order never changes.
