Musical double sharps doubt??

I have confusion, if you are playing a A major scale which has (C#, F# and G#). Then double sharp on F would mean playing G# OR G?? Please help me out. Please also clarify me with the sharps and flats theory.

Musical double sharps doubt??
You would be playing G if you had a double sharp on F.


Double sharps are a tone higher, while regular sharps are just a semitone higher. The same rule applies to double flats but lower.





It would be very unusual to come across a double sharp in a key such as A major. They usually occur in keys that have many sharps or flats.
Reply:g natural. The double sharp or double flat is just that: it adjusts by one whole step ALWYS the natural note.
Reply:double sharping means taking the note up a whole step making it G natural.. it is not double sharping the key signature rather telling you to double sharp the naturalized version of the note
Reply:Remember that "traditional" musical theory divides the scale in 7 tones and 12 semitones. Tones: C, D, E, F, G, A, B; semitones: C, C#, D, D#, E, F, F#, G, G#, A, A#, B. (E and B doesn´t have a semitone, so E# or B# doesn´t exist). This is the temperament theory (the theory that almost all the music from baroque to romanticism uses). This theory was used to organize in an easier way sounds (for example, for key instruments). According to it, a tone (except E and B) can be divided into two "equal" semitones. This means that C# (sharp) would be the same that Db (flat) (the first one is used when you ascend, the second one is used when you descend). This means, as well, that the ascending: C, C#, D, D#, E, F, F#, G, G#, A, A#, B; would have an equivalent (if you invert it) in the descending: B, Bb, A, Ab, G, Gb, F, E, Eb, D, Db, C (this time, no Fb or Cb, which are equal to E# and B#). So, every # has an equivalent b. Finally, a double # or double b would be equivalent to a tone difference. This means that a F## would be equivalent to a G, and a Gbb equivalent to a F... By the way, now a days, the strict musical theory deosn´t consider C# the same that a Db. But it is so for temperament. You could check out more at: http://en.wikipedia.org/wiki/Equal_tempe...


By the way, the tones for the A scale are: A, B, C#, D, E, F#, G#, A, (no F## in the strict scale, anyway, that would be, as we said, a G, but if you want a G, it would be easier to "undo" the # in G, than using a F##)
Reply:If you are playing Fx on a piano or other keyboard instrument, the key you are depressing is G. (F +1#=F# +1#=Fx) If you are playing an instrument of variable pitch, the note that you are playing is in fact Fx, which will finger pretty much like G but will need adjustment to be 112 cents below what your G# is.





Any major/minor scale will have one of each letter-name, which will be adjusted by sharps or flats (never both except in a few harmonic minor scales) to give the proper sequence of whole and half steps. If each interval is in tune, you have an extremely large number of different pitches per octave. By tuning "out of tune" one can limit these positions to 12 equidistant ones, as on the piano keyboard. But pianos are out of tune, even when they've just been tuned, because it is impossible to play in tune with only 12 pitches per octave.
Reply:It (F##) would be equivalent to playing the G. Is this in a piece of music you are currently studying?





That would be very rare in a piece in the key of A. Is it shown as F## -- the note head with a double sharp sign in front? If not, it is probably the cancellation of an accidental in that measure or the measure before or a courtesy mark (note with sharp (#) sign before). It would be a cancellation if there is an F natural of the same pitch earlier in the same measure, and a courtesy mark if there is an F natural in a different register earlier in the measure or in the measure before.





Without seeing the music, I guess it is also possible that it is a bi-chord (F#/G#) and the sharp sign applies to the G but looks like it's attached to the F# ... It would have to be G# in this example because the note heads for two voices places the higher voice (stems-up) after the lower voice (stems down) but there is no room for the # between the note heads ... but I'm probably going too far on that one.
Reply:It would be a G natural. Regardless of the key, a double sharp will always raise the note by two half steps, and in the case of F, two half steps above is a G natural.
Reply:G#. By the sharps and flats theory, what do you mean? How to find the key of a piece of music by the key signature? If so, then, if you are trying to find the key of a song with flats in the key signature, find the second to from the right flat, and that is what key(flat). In sharps, find the on furthest to the right and go up one(line or space) and that is your key. I hope that is what you mean. Sorry if it isn't.

Reply:The only reason for a Fx (F double-sharp) in the key of A would be to modulate or tonicize G# minor - an usual choice for certain, depending on the strictness of tonal relationships in the music.
Reply:G# surely? and what do you mean by sharps and flats theory? =S
