Interval
2 Method
Based on the
Circle of Fifths, I noticed that all major scales that
contained sharp keys began on a white key (except F#) and
all major scales that contained flat keys began on a black
key
(except F).
I also
noticed that when moving towards the right or up from C, the
number of sharps increased by intervals of 2.
When moving
to the left or down from C, the number of flats also
increase by intervals of 2.
Looking at
the piano this way made it easy for me to remember how many
flats and sharps each key had.
Here, you try it!
Using this
formula, see if you can determine how many sharps or flats
are in the key of G? What about the key of
E♭?
