I know this sounds stupid, but what is breath control?
is it just supporting your breathing with the diaphragm and being able to play long passages without taking a breath?
Breath control is about controlling the air-stream which you send into your oboe and concerns the speed and the volume of the air and you do this by using your diaphragm. (Actually I think from a strictly phsyiological point of view that is not quite true and that the muscles which do the work have a different name but the name is not really that important).
My oboe teacher has a huge number of images which he uses to describe how you do it. I think he has so many because different ones work for different people. I can only really remember the ones I found helpful these include:
- imagine your lungs are a half-deflated balloon and then imagine a pair of hands squeezing the bottom of the ballon (the bottom of your lungs) and forcing the air up to the top (and down the reed).
- get someone to place their hand gently on your stomach and as you play try and push their hand away with your stomach muscles.
- to play quietly imagine you air-stream is like air coming out of a tiny puncture in a bike tyre. (For forte, imagine the air is coming out of a puncture in a lorry tyre).
What is important is that you keep the air-speed constant. One way of visualising this, which my daughter found helpful for the trombone (but she is only nine and this might be too babyish for you), is to put a tiny bit of water in a glass and then blow into it with a straw for as long as possible, making sure the bubbles you make are always the same height.
Don't know if this is any help.
