i got a professional oboe from my school which by the way is so Y2K it`s not evan funny but it has a 3rd octave key and the extended 1st right hand key i may be a total idiot for this but what are these difference from the intermediate horn for

The 3rd Octave key will help you make the High E and F and G G Flat (F sharp) clearer, in a way. I own a Loree and I never use it. I don`t really know the other key you are talking about.

P.S. Very few oboists use the 3rd octave

I have the 3rd octave key but I never use it... maybe if my teacher tells me to do it but not when I`m alone.

The third octave is pretty useless, unless you have to sneak in on a high G at quadruple pianssimo-even then its use is arguable. The F# extension (first finger right hand) is to help create a much more natural hand position on the oboe. All you have to do to convince yourself of its application is play this "pro" oboe for about a week then go back and play an oboe without the extension, you will immediately notice a difference.

My teacher has her 3rd octave key shut off....when i got my loree, it didn`t have a 3rd octave...i really don`t like them. It`s just another hole in the instrument. I think 3rd octaves change the sound of other notes by just being there...as i said, another hole in the instrument.

Oh no, wait, I think the octave 3rd key makes an oboe really professional... yeah it`s useless if you`re just a student but very very important in a big orchestra!

the third octave key is a recent invension. Most older (in the last 10 years) professional oboes don`t have the 3rd octave key. It`s only good for a few notes, and often makes those notes sharp. Lorees didn`t have the 3rd octave key when my oboe was made in 1989. I don`t think that it`s true when you say that a 3rd octave key makes an oboe professional. There`s many non-professional oboes with 3rd octave keys and many professional oboes without them! It`s all matter of opinion though.

The third octave key doesn`t make an oboe professional, but in the latest 6-7 years almost all the professional oboe have that key. It just means that it helps a lot if you have to do difficult notes

When I got my Lorée, the 3rd 8ve key was closed all the way. They are only supposed to open a miniscule amount, but the key couldn`t be depressed at all. My teacher was becoming quite angry with me because my high notes - F#, G, G#, etc - weren`t working with the third octave key, but were with the first. I was cleaning the oboe, and had the keys off, and noticed a piece of cork placed in the hole.. a "shut-off" if you will. After removing the cork, they spoke beautifully, with very little force. It`s all a matter of taste. Which sound you like best and which is easiest for you - on the high notes, of course.

I use it for the high E, F, and F#, but I don`t know the fingering for the high G....

High G is half hole Bb....so like you finger the middle Bb with the first finger half-holed instead.
