Just thought I share some knowledge
Start with your first tone/degree C your 1 and keep going to your fifth tone which is G-5 right. The scale of C has no sharps. Your G has 1# which is F#, then you play the fifth tone of the G scale which is D. D has 2 #'s why? Equation of Scales whole step, whole step, whole step, half step, whole step, whole step, whole step, half step. Look at the D scale it's 1-D, 2-E, 3-F#,4-G, 5-A, 6-B, and 7-C#. Then you play the fifth tone of the D scale which is A and A has 3 sharps, you should notice the pattern of the scales going up with the fifth tone. If you can understand this then you are on your way to knowing scales a little more.
