Hello,
A friend and I were discussing the split D key (right hand 3) and it's purpose. Pressing the left hand E flat key causes the lower part of the key to close, improving the intonation of the D-sharp-to-E trill. Everyone seems to agree on that. What we can't seem to find an answer to is: Why can't the left hand E flat key lower the whole RH3 key? Why does it need to be split?
I've looked at many fingering charts for a note that requires left Eb and NOT RH2 and also NOT RH3, as they close the tone hone that the top part of RH3 closes. If there exists such a fingering, I could see how this key would need to be split. I've found a few, but nothing of significance, so I feel like I must be missing something obvious.
I came up with the example of going from Db to Eb to Ab: pressing both left Eb and left Ab at the same time, but I can't hear a difference in the sound of the Ab by adding or removing either Eb key. There are a few other examples that are even more obscure from http://wfg.woodwing.org/oboe/ob_fing.html, but none of them really made a difference in sound either, so I bring it to you.
TIA
