    Quick Q on Key Signature's

    If, for example, I am looking at the key of G on a staff, the sharp is on the top ledger line (F#). Is it understood that all the F's in the piece are also sharp?

    Yes, all Fs in all octaves. Of course, there can be parts in the piece where theres a temporary accidential, but in general it means that all Fs are F sharps.
    I attached a quick Ptb, with a simple scale sequence. I threw in a few odd notes to demonstrate what would happen if youd play a note that isnt normally in the key of G.
    Hope this helps

    Oh, its really no biggie. Not that important to check out the file. Basically just a simple example meant to show what has been said in my reply, so its not that important to check it out. Just wanted to add that to make it even clearer =)

    I'm sure it will be helpful. I am working through the sometimes painfull process of sight reading. I was just putting some stuff on powertabs and realized I needed to be in the Key of G, so when I changed it all the sharps went away. I figured the signature denoted all flats or sharps for the notes shown, but thought it best to ask.
    Anyway, thanks for the quick response.

    Yes, that is true. The accidentials at the beginning of a score show you the key its in, by telling you which notes to add a # or a b too.
    Example, key of C has no accidentials.
    1 # = G maj
    2 # = D Maj
    3 # = A Maj
    4 # = E Maj
    5 # = B Maj
    6 # = F# Maj

    1 b = F Maj
    2 b = Bb Maj
    3 b = Eb Maj
    4 b = Ab Maj
    5 b = Db Maj
    6 b = Gb Maj

    As you noticed, the #-list ( G, D, A, E etc. ) moves in fifths, the b-list ( F, Bb etc. ) in fourths. Basically, the cycle of fourths / fifths gives you exactly that information.
    Regarding G Maj, that key has the notes G-A-B_C-D-E-F#-G, so naturally, the beginning of the score should have a # on the F-line, so all Fs are played as F# ( theoretically of course, cuz some pieces have exceptions... for example, a F or C# or whatever thrown in, although most of the piece is in G maj )
    Hope this helps
