Hi Chris. Again, the information you provide and your time in doing so is appreciated. I wish there were more users on this forum as active as you.
Which altissimo notes are you thinking of that use left Eb and not RH2 and also not RH3 and also not the C key?
From http://wfg.woodwind.org/oboe/ob_alt_3.html:
C# doesn't use left Eb.
There's one D that uses left Eb but it also uses RH2: halfhole, LH2, LH3, left Eb, RH2, C key to "fake" the Philly D key when slurring.
D# can be played halfhole, LH2, LH3, left Ab, left Eb, RH2, C key...but there's a RH2 in there.
E and F use RH2 and RH3 for fingerings that use left Eb.
There's one fingering for F# that meets the criteria, but it comes out as a sharp G for me, and I find no difference in pitch to timbre by using right Eb instead (either way, a sharp G is unusable as an F# in real life): octave key, halfhole, left Ab, left Eb, RH1.
G has the same thing as F#, but with a C key added, which closes RH2 and the vents for F# and keeps the forked F vent closed.
G# doesn't use left Eb
The A's, A#'s, B's, and C's that use left Eb also use RH2 or RH3.
The one fingering for C#(7) doesn't use left Eb.
I think I understand what you're saying about RH3 being necessary to allow left Eb to open the Eb vent for some systems, but I don't see why that would require the key to be split. Either way, wouldn't that trill leave RH2 down (closing the F# vent and keeping the forked F vent closed)?
I agree the split RH3 key is an elaborate design and I'm all for overly complicated keywork if there's a reason for it: I would love to see Philly D key as a standard (Loree for example clearly has the designs and molds/casts for it...I can't imagine the tiny bit of material and one screw would add over $200 to the cost as it does aftermarket), left C#'s standard instead of the worthless banana key, have RH3 cancel left F, and maybe a link to close the C key when fingering low Bb (definitely) or low B (...maybe), I also think RH1 should be drastically extended as a standard to prevent hand/wrist problems, but that's another story. For this topic, I'm still trying to find an example fingering that demonstrates why RH3 needs to be split.
