Here it is, finally!!
After countless comments asking about the little cork on my C key and my fingerport and thumbport, I decided to put all the questions to rest!
I did, however, completely forget to mention why I ultimately chose open-hole, but given that this was my professional flute, open-hole was standard. I'll probably talk about it more in a future video, but I am pretty interested in newer music, which tends to involve things like pitch bends and slides. It's actually impossible to do slides and quarter tones on closed-hole flutes, because you actually need to cover half the hole(s)! So open-hole for me, it was...
As you can tell, there was a lot of thought put into every little customization and gadget I put on my flute. I cannot stress enough that no one should copy everything I do on my flute!! You may end up hurting yourself, if my customization doesn't work well for your body!
Do your research and take lots of time to observe how your body works with the flute. I didn't get all these gadgets at once! It was a slow development over many years. The best part of about customizing your flute to yourself is that you not only learn so much about how your own body works, but flute playing gets easier along with it! ;)
