I'm guessing this probably isn't right, but it seems to help my concentration... is there some sort of breathing technique I should be using?
I think it's completely normal to hold one's breath while attending to a chunk of text or a phrase of music. If you watch a baby picking up a new toy you will notice his breathing becomes laboured as he focusses attention on the new object.
I suppose that by the time a piece is mastered, little or no thought is required during performance, and therefore less holding of breath will occur. Interfering with the breathing would seem to be unwise since that will interfere with thinking.
Taking the idea further, it implies that, just as Skylark talks in long sentences, wind players and choristers will tend to read more efficiently than pianists.
And presumably musicians generally will benefit from being aerobically fit (and therefore having greater lung capacity).
