I have serious problem with breath. I don't breath very fast and when I have to 'steal' breath in the middle of phrase I make big pause and that sounds awful. Well, it's not only in the middle of phrase, that always happens!
Advice?

you don't make noise when you breathe normally, so you should not make noise when you breath during a piece, this is a sign of a tight throat and embochure

If you can do some relaxtion exercises and long tones and take relaxed breath, the problem will go away

Also be sure that you are not chest breathing. It's a natural defense mechanism to prevent the absorption of pollutants, and is very common in urban areas, but chest breathing will limit the amount of air you're taking in. If you lie down, and put your hand on your abdomen, you should feel your diaphragm expanding as you breathe (It's very difficult to breathe in any other way while lying down). This is the same feeling you should have when playing. Be sure to fill the bottom of your lungs to the top, and that you breathe whenever the chance arises. Don't treat breathing as a chance to completely refill, but instead as a chance to top off the tank. Anywhere there's a suitable break, you should be taking in some more air, even if you don't feel a dire need for it exactly at that time.

under normal circumstances one should not breathe loudly or in a gasping fashion, but, of course, if one has a cold, sore throat or any other malady, breathing will be affected by constricted lungs..

you should hold any note as long you 5 times in a row every day
trust me it works

sry
as lomg as you can

That may help expand lung capacity, but will not improve the depth or speed at which you breathe in the middle of a phrase. It's a good idea to work on expanding your capacity, but probably won't help a whole lot in this instance.

Take a quick breath if you really have to. If you're holding a note out and everyone's playing with you, kinda slowly decrescendo out the breathe and slowly come back in. Plus increase your lung capacity.

holding a note a long time is only good if one does something with the note, such as altering the color, shading and edge, etc, a long airy tone is counter-productive

Sorry to read this, Micro, I hope it does not conflict too much with your playing.

When I was a child, I had so many and frequent bronchitis that doctors and parents feared there could become chronic. I was lucky and it did not happen; the condition just dissappeared in my early teens.

Looking back, I now attribute that problem to two possible coincident causes: Cold and very humid winters plus my father's cigarrete smoke.

However and though I do not suffer from any known pulmonary problem, my chest radiographs always show dark spots that leave doctors (and me) worried for a while. They are probably scars left by those early infections.
