Put another way, the intervals in a major scale go like this: whole, whole, half,
whole, whole, whole, half.
If you start your major scale on C (the C Major scale), you end up playing all
white keys on the piano. C Major is the only major scale that uses only the
white keys; all the other scales have black keys in them.
To make things easier for you, the following table shows all the notes in the 15
