Music Theory Grade 3 Test

Hi David,
I asked the same question on a different thread. Here is the answer I got:

Major Scale Theory

The reason is when you write out a scale you use every letter once. In the F# scale F is the 7th interval so it is written E# because the F has already been used Also if you called it F there would be no E in the scale F# G# A# B C# D# E# F# Same goes for the other scales Just wait until you learn about double sharps and double flats

There were a couple of other answers. You might want to have a look at those too.
