Re: Alternative G#/Ab key

You should still be able to use the RH side G# key on a dual system as you can on a regular conservatoire system for a G-Ab trill (or for an alternative G#/Ab) so long as you lift off RH1 from its fingerplate immediately before you use the side G# key as the LH1 fingerplate holds the G# pad cup closed. So you can't use this key at all while RH1 remains held down.

If there are two side keys, then the upper (overlapping) side key is often there for the following:

- On pure thumbplates (if fitted) it's a side G# key (for a G-Ab trill),
- On ring key conservatoire systems it's a side Ab-Bb trill key (play G#/Ab and trill the upper side key),
- On full Gillet conservatoire systems its a G#-A trill key (hold it down and trill LH3).

There are some rare 'English System' full Gillet-style oboes that are pure thumbplate system (no link from RH1 to the top joint) but look like a full Gillet conservatoire system with all the perforated fingerplates and Gillet conservatoire mechanisms (RH3 split D#-E trill, etc). Both Howarth and Loree built them to order and the upper side key on these is either a G#-A trill key (as on regular Gillet conservatoires) or duplicates the thumbplate action to trill the Bb and C keys as the side key does on a pure thumbplate system oboe.
