Proper Use of the Glottis in Trumpet Playing

[Brassman19]

Hi. I was looking online yesterday at some trumpet-related things, and happened upon an interesting link to a scholarly study and paper by the University of Miami (FL) into the proper use of the glottis when playing the trumpet, along with the effects of its improper, or incorrect usage, and methods/exercises for remediating improper glottis usage (the treatise is called, "Strategy for Proper use of the Glottis and Implications in Trumpet Playing").

I thought other TH members might like to read it, and consider its findings and suggestions, particularly those of us struggling with issues in our playing which can't seem to be clearly defined, nor remediated easily or successfully. Its link is below:

I have read about a quarter of the way through it so far, but what I have read has helped to give me some insight to the possibility that I may be improperly using my glottis in my comeback efforts to relearn the instrument, plus in my playing, particularly in the upper range. I find it all very interesting, and it is giving me a lot of food for thought personally. I hope perhaps that some of you fellow TH'ers out there may also gain some benefit from it.

Thanks for the article. It brought to mind the use of "throat vibrato" on trumpet.
