Hi all, I'm new to TrumpetMaster so I hope I'm posting in the right section. I have a query about inconsistent playing ability... I've been playing the trumpet for just over 10 years now and am looking to pursue music college sometime in the near future. However, I've recently noticed that my playing is somewhat inconsistent during practise - most notably my range and flexibility. Come to think of it, my playing has always been rather unreliable; some days effortlessly being able to play high C and above, yet on others, barely managing to play anything above the stave without noticeable tension in the neck. I understand we all have good days and bad days but I'm just plain unreliable! I don't feel like I'm doing anything different when I have these "off days" so I don't know what's going wrong. I was just wondering if anyone else has experienced this problem for some suggestions as to what might be the cause of this inconsistency. (Could my mouthpiece be too big perhaps?) (I practise regularly for around 2 hours a day taking breaks every 20 minutes or so and often having one day off a week to rest/recover). Thanks in advance, any feedback would be greatly appreciated.
