Hello, I was just wondering what does the bore size of a trumpet change other than the fact bigger means more air needs to go through it? Like eg: a ML bore .459 vs a .462 large bore... How does that effect sound? Is it going to be brighter/woolier or is it just going to change the 'bigness' of the sound rather than the color of the sound? Will it add more volume/projection? Also, can it 'offer' more if you can blow through it compare to a smaller bore and yet be used for the same stuff a smaller bore can to (meaning its just better if you can handle it as it offers everything a smallbore does + extra) I think thats about it. O btw- My other user name was Gxman, I couldnt remember the name so I thought it was deleted then I found it, has 200 or so posts on it, o well, starting again now.
