See...now I think we're splitting hairs here and frankly it's getting quite frustrating. I'm curious to know which recordings you saw Mr. Clevenger (and yes, when referring to him in public, I will most definitely use "Mr. Clevenger." When cursing at him or speaking of him in private, perhaps not...) using headphones for any other reason than checking HIS specific balance. What I'm trying to say here is simple... if dealing with "studio" musicians, you won't have a problem with them wearing cans for clicks. However, since there aren't that many classical/soundtrack studios in the Philly area, I'm supposing Joe will be dealing with symphonic players (as he has already indicated). I can tell you from personal experience....as a professional horn player only 3 hours outside the Philly area, that there is a slim chance of finding 4 to 5 horn players who are comfortable wearing cans while playing. A clarinet, a bone, a trumpet are all notable exceptions as these guys have likely played in studio sessions. Horn players though work entirely as a section. We don't breath without the others' approval. The commradery (sp?) in a horn section is unlike that in ANY other orchestral section and the headphones WILL hinder our communication. In other words...I am NOT an isolated case. My suggestion TO JOE is simply that he be cautious in his approach to get "SYMPHONIC" players to wear headphones while playing. I guarantee you...piss off ONE of the hornplayers and you will gain the wrath of the entire section! Differ in opinion all you would like, but don't tell me that I'm an isolated case. I KNOW the other horn players in the mid-atlantic area and I KNOW their preferences in this matter.
