Sorry I've been posting a lot recently, I don't like to be a burden. But... Basically, I understand the concept that faster air makes a higher note. But when I do that it also makes a louder note. If I don't it begins to sound thin and airy. I realise I am not phrasing this well, but what I am really trying to ask is how do you play higher whilst keeping the same volume (or getting quieter)? Sorry, for this vague question... but hope you all get the gist. I do have a teacher, but I will not see him for a week and he asked me to work on my air speed/support for next lesson. And what is this apeture adjusting thing? I don't really understand... I thought the air controlled the apeture? Anyway, thanks for any advice. I don't want to ask too many questions in one go!
