So clarification for the title, I play euphonium, but not as a primary instrument; I am primarily a French horn player, but I spend a great amount of time also playing trombone and euphonium, depending on the type of ensemble I’m in and the instrumentation needed.
A brief bit abt my experience is that I am actually in undergrad for music education and French horn performance, but I have picked up trombone a few years ago for jazz band and then I learned euphonium in my brass methods class this year, and took off with it rather quickly, and decided to double more on euphonium lately. I still regularly play horn and I have figured out my own needs in adjusting technique between the different brass instruments I play, but I’m also just curious about getting some of my own gear for euphonium.
Currently I am in marching band at a university where I play marching baritone, which I am loaning from the school, which comes with an older King mouthpiece that I can’t remember the number, but I think it said something like a 5C or something? It doesn’t feel as small as a Bach 6 1/2 AL, but not significantly bigger. There is significant wear on this mouthpiece on the rim and I also was curious about trying out deeper cups for better projection and clarity in my lower range while on the field. I also have been wanting to just get my own large bore euphonium/trombone mouthpiece for the times I have to borrow a large bore trombone or euphonium, since all I have in regards to what I own in low brass gear is a small bore tenor trombone and a small shank Dennis Wick 7CS for my jazz setup that I’m fine with.
I was eyeballing something like a Bach 5G for euphonium, as I tried a Bach 6 1/2 AL both on trombone and euph but it doesn’t feel deep enough for some of my lower range needs for it to be designated as a solid all-around pick for me. As far as my tendencies on euph vs. horn, I am completely ok with projecting and having smooth tone in my upper range on euph, since I’m so used to the small mouthpiece of a French horn. I can play low on euph, but it’s not very loud and I tend to have some minor issues in tone and intonation as I am still navigating the feel of centering my air in a larger mouthpiece (it’s getting better tho fs).
For any French horn players who play euph as well and want to know my preferred setup on horn, I currently use a Houghton Horns H1 cup with a 18mm Houser E Series rim, but I also enjoy my Laskey 80G mouthpiece as well. Generally I don’t like anything that is less than 18mm in diameter for the rim. Do what you please with this info lol. Lastly, I was curious abt Laskey’s line of euph mouthpieces, including their baritone stadium series mouthpiece if any of yall tried it, I just have good experiences with laskey mouthpieces on horn, so I wonder how they do with the other brass instruments compared to other brands like Bach or Schilke.
TL;DR: I am a horn player who doubles on euph and trombone, currently looking for a large bore mouthpiece that will help with low range projection, preferably something that would work well for marching baritone as well (the baritone is large bore)
Edit: the mouthpiece that came with the marching baritone I’m lended is a large shank King Marcellus (no other engravings on the mouthpiece, based on my assumptions with a public university’s band budget, it is likely taken from another horn, because I’m playing on a Yamaha YBH301M)
