| dcstep,
What is it with these trumpet website forums? Did I say I thought someone was trying to stop the discussion? "Little built in compression" and "free blowing" ... esentially the same thing. Semantics again ... who said there was a differece in the two?
Let's try to think only of the mpc (for discussion sake) for right now.
A "high cpmpression mpc" do you know what that is? Shallow cup, smaller bore hole, tighter back bore. For a lead trumpet player in a big band, this type of thing "in general" ( sure I know guys that play 3C's and do well ) allows the compression to happen at the lips/mpc juncture rather than having to create so much compression in the body, the endurance and ease of the upper register. Also tends to help create a sound more suited to the style.
A free blowing / low compression mpc ... a Bach 1, 24 bore hole ... freer blowing, lower compression ... but will take more body compression to get notes to speek. Sound probably more suited to legit styles of playing.
Where these terms relate to a horn only ... pick a variable? Since there been so much emphisis on the "bell", we can talk that.
And here too ... many variables effect the percieved resistance factor. Bell thickness, annealing or not, proper vs improper bracing, plating.
If the bell doesn't "ring" / give the pizzaz you want, or if you can't hear your self, you work harder to get the sound you hear in your head. You work harder, more compression in the body to the point of building up too 'backpressure' ... then you work harder yet to over come what you might percieve as resistance ... visious circle.
