I’m looking for some pointers as to how to help my 10 year old correct his playing posture/embouchure. He’s reached grade 4 standard but unfortunately his last teacher allowed a lot of technical issues to go unchallenged and it’s now proving a real struggle to correct them. The main problem is that he seems to have difficulty in maintaining the clarinet in the midline - the mouthpiece appears to deviate towards the right side of his mouth and thus the instrument isn’t aligned with the centre of his body. It looks very bizarre! His cheeks also puff out particularly on the right. As it’s become such an ingrained way of playing it he has no self-awareness that he’s doing it. We’ve just started with a new teacher but it’s proving very difficult to get him to change his errant technique.
