Please please be nice if replying, because I don't find this easy to write. I played cornet as a kid, and while I wasn't brilliant, I did sit in the front row in the school band and high C's were not utterly impossible for me. After a break of some decades I have come back to playing, and while I love playing, I have found it an uphill struggle all along, and general stamina and ability to play high notes is utterly lacking. I have spent years with G (space above the staff) as my highest playable note and I just can't get higher. I am making progress, with a teacher, on E's and F's. I have always breathed well (since childhood) and I don't use too much mouthpiece pressure. A while ago I worked out that pelvic floor strength was a major issue. Not completely surprising at my age, and, I've had kids (with accompanying birth injuries, I was previously a midwife, so I have some idea what happened to me). I took up pilates and I do this regularly, and this has been good for these muscles. However I still know if I don't engage them, I mean really really engage them deliberately before a note, anything above D or E, my bladder muscles just won't cope. The higher the note, the more muscle power I need to, ahem, stay dry. (I did say this was difficult to write). My teacher has noticed (bless him) that I get all tense when preparing for a high note. Well, I think some muscles make me tense all over, and I'm not entirely in control of that, I just don't want to wee over his lovely carpet. I don't find it desperately easy to discuss this with ... a man. Going back to midwifery experience, I know I'm not the only one to experience this, and I think brass playing is a pretty stiff test of pelvic muscle strength. If having kids means I can't expect to play above a G, then I'm ok with that, and given the choice, I'd stick with the kids. But I would like to know. Has anyone else dealt with this, successfully or unsuccessfully?
