also...whats a double-sharp?
example:F## on D#(Major)?
Well, there are a lot of potential ways, and there isn't space to get into them all--not that I even know them all, or even close--so let me just mention a generality or two.
Knowing scales can help you understand how and why different combinations of notes sound the way they do. This, in turn, can help you understand how others get the sounds they do, so you can avoid, borrow, refer to, or steal those sounds. It can help you get the sounds you hear in your head out into your hands, and it can help you hear new sounds. It can help you play the things you hear. It can help you with harmony and with building parts. That should be enough to start with, right?
A double sharp is exactly what you think it is. Instead of raising a note a half tone (one fret), you raise it a whole tone (two frets). C double-sharped, in our tuning system, sounds like D (that is, the two are enharmonic equivalents). For analytical purposes, however, C double-sharped is different from D. BTW, double sharps are usually notated with a symbol loking something like an x, or a multiplication symbol, rather than two sharps. I have no idea why, but that's how it is.
