I’ve had the opportunity to own a bunch of modern simple system flutes and try out a fair number of other peoples’ flutes. Among these I’ve owned several Copley D flutes in both wood and Delrin (still own one) and have tried at least 3 others. I concur with Jonathan (Paddler): Copley flutes have no unusual playing characteristics with regards to vented/non-vented 2nd register D playing/response, or otherwise. They are certainly among the most beginner friendly flutes one could own.
Do you have the oval embouchure cut or the more rectangle cut? For some, the embouchure hole shape can initially cause problems if you are switching from one to the other, though I doubt that’s the problem here, but it’s worth mentioning as part of the differential diagnosis.
I do agree with others that this sounds like an embouchure development issue and I would guess one or more of the following is to blame:
- Your (lip) embouchure aperture is too large and/or the wrong shape.
- Not adjusting airstream angle for each register.
- Simply blowing harder to jump register, usually in conjunction with #2, and/or over tightening the lips.
- Not directing your airstream to the ideal place on the embouchure edge (too far left or right) and/or hitting that spot with the flute or your head/lips not parallel to the embouchure edge. Yes, there are photos and videos of great players who break this “rule” and make it work, but it’s probably not a good place to start if one is having difficulty.
I also agree others that venting the top hole is the recommended proceeding for best tone and intonation on 2nd register D, but in practice, on “most” modern simple flutes it shouldn’t be necessary unless you are extremely sensitive to pitch and note to note tonality, particularly in fast tunes.
Still, if you are in the early stages of learning to play the flute (first few years), might as well train yourself to vent now as it may come in useful in the future, say for getting the optimum tone, tuning, and volume when recording, though people seems to be fixing everything in post these days. I suppose it won’t be long before Logic and Pro tools have AI integration that allows you to simply upload your flute track and use the voice command “make me sound great!” Or perfect, or like fill in the blank with your favorite player’s name. Just a matter of time before the software can’t automatically take your solo flute track and adjust everything from tone, intonation, dynamic variation, and rhythmic timing and variation to emulate virtually any player you can feed into the AI to train it. Pretty grim. But I digress.
Whistles are a bit different with regards to venting than flutes as some whistles can really need a significant additional breath pressure to jump octaves without venting, which often leads to an unnecessary increase in volume right where you don’t want it. Another good reason to get in the habit of venting.
All of that said, there’s certainly a case to be made for venting only when it’s more or less needed on the flute, as most of the time nobody is going to notice one way or another, and keeping the top finger down just makes things easier, quicker, etc.
Either way, regular use of some of the embouchure exercises already listed should help resolve your issues: Long tones, D,d,d’, E,e,e’, etc. Suggest you read this thread where Brad made the exercise recommendation that was referenced earlier in this thread, as there are some interesting details as the thread developed. Geeze 2004, where does the time go
