An Accidental case dealing with clefs

[allchopin]

What happens when an accidental in the bass clef (that has temporarily become the treble clef via a manual conversion with a little treble symbol at the beginning of the measure) is placed (while the normal treble clef stays treble)- does this apply to the normal treble cef as well?  Basically, do accidentals ONLY apply the their staff line in ALL cases?

[Rach3]

I think the rules are that accidentals would still only apply to the one staff (otherwise the other staff by itself would be incomplete). In what piece does this become an issue?

[allchopin]

What do you mean by incomplete?
I havent actually found a case of this but i know it could happen...

[NetherMagic]

I think accidentals apply to other staff lines as well with the same key, for example if I sharp a F in the bass clef and then I immediately have an F with a higher octave I think that would be sharped too

I hope that's what your talkin about there allchopin, cuz frankly your msg was kinda confusing   but then again not all things are easily explainable =]

I'm pretty sure of what you mean.   I would think most of the time they would mark it if it was going to be the same.  Technically it makes sense that it would stay the same, but I don't think there would ever be a situation where the composer didn't mark it.  I think if they didn't mark it, then play it according the key signature or accidentals in that line of music.

This should help, despite my mspaint drawing skills.
(and btw, a note in octave(s) above is NOT changed by accidentals in octave(s) below)
