Well, my teacher played it in today's lesson, and of course it sounded fine in his experienced hands! He did, however, adjust the head joint slightly, and that seemed to help. The rest, it seems, is down to me

although he did mention that he thought I was trying too hard.
It's very frustrating though, when I struggle to get a good tone, and people like Robodoc (no offence, Robodoc, if you are reading this!) leap from beginner to Grade 5 in two minutes! By the way, if you
are reading this, Robodoc, how much practise did you do to get so far so quickly?

Edit: yes, Judster, it has the E mech.
Hi Misterioso,
I suspect that you may be trying too hard and the flute is reacting to tension in what you are doing. Advanced flutes such as the Miyazawas are
very sensitive to this kind of thing.
This isn't what you want me to say, but it may simply be a case of being patient until you grow into your flute. Miyazawa flutes are advanced instruments, rather than beginner or upgrade models (and if I remember correctly you've posted before saying that you have a solid head Miyazawa). You've upgraded at pre-grade 5 level to a flute which would normally be played by grade 8 and diploma standard players. Advanced flutes are capable of greater flexibility and a broader tone palette compared with beginner/upgrade models
but they also require greater precison with things like your embouchure and are far less forgiving of a less-developed technique - meaning that mistakes and problems will show up more with the flute you have than if you were playing on a beginner or upgrade model. This shouldn't be a problem in the long term, but may mean that you sound less good until you have the technical ability which your instrument expects.
The fact that you've changed to an advanced flute so early makes comparison with other players more difficult because at your level it is easier to get a good sound out of a beginner or upgrade instrument (and these are the flutes which most people of your standard will be playing). Please don't be discouraged if you think that people like Robodoc are doing better, it will probably even itself out in the end and you won't have to spend time adjusting to a new flute later on (which can take ages).
You probably will also find as you improve that you keep running into patches where you feel like your tone on certain notes is getting worse. Often it will actually be a case of you going from a point where all your notes were of a similar standard to one where some notes have improved and others are yet to do so. This makes the notes which haven't improved yet sound worse in comparison to the ones which have - even if you have in fact improved on everything.
