So I just received my new piccolo trumpet; it's a Selmer Maurice Andre with Blackburn pipes, and I love it so far. I've mostly been working on the low register and just practicing making the horn sound good. My high register is where it needs to be for the moment (F5 on picc and E6 on Bb), so I'm working on tone and fingerings and really taking time to make sure each note doesn't sound like a kazoo through a megaphone and using less air and effort to really let the horn sing.
With all of that said, right now I'm playing with a Schilke 14a4, which I have always used for baroque tunes on Bb. I have been playing this mouthpiece for 15 years and am very comfortable with it. On picc, though, it kind of feels like I'm trying to play notes through a brick wall, so I'm trying to decide between mouthpieces. Bach 7e, Bach 7dw, and Schilke 14a4x. I know the Bachs are probably the most prevalent and known to blend the best with others, but I'm not playing with anyone; I'm just a private teacher and a private player. I lean towards the Schilke just because the 14a4 is the most comfortable rim and cup diameter I have ever played on, but I also know that anything with the "a" cup is known for being way too shrill, but I don't know how that translates to picc. So, saying all of this, the 14a4x is the way to go, or is the Bach the way to really make the pic sing instead of shriek? And also, is there any mouthpiece I'm missing out on that has the same kind of rim and cup diameter as the Schilke that has but also has the open backbore meant for picc? Thanks!
