Hi,
Could you please tell me where I could find a fingering chart for microtones on the oboe?!?!

Hi there. It is an interesting question. First off, The only microtonal fingering chart that I have found is in an Italian book called The contemporary Oboe by Andrea Chenna and Massimiliano Salmi.

It is very small and confusing. Let me preface this by saying that I have been playing in a contemporary woodwind quintet professionally for the last 10 years or so. What I usually do, is to experement with adding keys or half keys to the basic notes until I find what I like.

I know it may not be as spacific of an answer, but I hope it helps.

Take care

in most microphones (or multiphonix) you have to stick the reed longer into your mouth than usual. You can do that and the fingerings for eb```
