So, I have the highest grade in my AP Music Theory class, a 98.8%... but I've ran into a problem that I just don't understand, hopefully someone here understands this.

- I have to notate at B# Augmented Triad.
- Now, to keep the correct "form" of a triad, the notes must be some form of a B, D, and F.
- The root is obviously B#
- The third is D# because in the "key" of "B#" D will be sharp.
- The fifth is a tricky one. On a B# Major chord, the 5th will normaly be a F double sharp, but to augment it, you'd have to raise it up a half step making it an F triple sharp.

Now, I've looked in Oxford Dictionary of Music, and it dosn't mention anything about the existance of such thing as a triple sharp. Knowing that a sharp looks like this "#" and a double sharp looks like this "X" would it be right to assume a tripple sharp looks like this "#X"...


If anyone could help, that would be just awsome!

Thanks,
David

Ouch! I have a headache now!

I am sure someone around here will be able to help with your question any second now......but it won't be me. LOL.

Good luck!

Well, wouldn't D also be double sharp? And yeah, since we're into theoretical chords structures, I guess the F#X would be the way to go.

Nope, the D would be just one sharp, the only thing that changes from a Major triad to an Augmented triad is the 5th raises a half step, the the third stays the same as when its in Major mode. But thanks for the help, since at least one person agrees with me, I'm going to go ahead and put down F#X and see what happens tomarow. But question is still open for discussion if anyone one would like to chip in.

I'll keep you posted on what my teacher has to say tommarow.

But isn't B+ spelled B, D#, FX? Therefore, B#+ = B#, DX, F#X? Am I overlooking something?

Oh crap... Yes... You are right.

Thanks, haha.

B#-DX (double sharp)-F triple sharp

But why do you have to put it in the "key" of B#? Or in any key?

Couldn't you just use the notes B# - Dx - Fx (the x's being double sharps).

Norm- It MUST be a triple sharp on the F; this is the enharmonic equivilant to a C augmented chord, which would be spelled C, E, G#; therefore B#, DX, FX#.

88-I just tried a triple sharp in Finale. It notated it as: #X. Never seen one before; never hope to, but now I'll know what it is if I see it!

Thanks, I never even thought about trying it in finale and seeing what happens. But it looks like it does work.

Thanks
