Two valves?! Amazed Eeek!

This is going to be one heavy beast!

You planning to use the bell brace for support?

This thing is shaping up to be one impressive horn! I can't say I've ever seen a two-valve dependent contra before. Is the second valve going to be in D like on a dependent bass bone?

Yes, D with both valves combined. Minick made 2 dependent contras, I believe, so it has been done.

Sorry if this is off color but this thread is Trombone Porn. I'm eating it up. I wanna touch it.

Seriously that thing is beauty and the beast all rolled into one. Can't wait to hear it played.

Hi all!

The contra is all together! The F and D wraps are finished. Next thing to do is fabricate trigger levers, buff and prep and then off to silver-plating! This beastie makes a great noise.  Amazed Amazed

Never look at the conductor. You just encourage them.

Have you noticed, some folk never stick around to help tidy up after practice?

It's allowed under the terms of the North Atlantic Trombone Organization.

My wife looked at the picture, and she says she believes that Brad and Noah were over in North Korea testing that beast today. The test resulted in the 5.3 "artificial" earthquake. (Flutists have a generally low opinion of trombonists. I still don't know why she married me.)

Apparently we can absolve the North Koreans of the suspected nuclear test today.

Seriously -- nice work, Brad.

I think you've muddled up the causal relationship there.  They have a low opinion of trombonists because they marry them.

Where does the warning flag hang from the attachment tubing?  :)  You're gonna need about 3-4 feet clearance from anything behind you.

The loop is actually a mute holder for the trumpet player sitting behind you.

I was thinking it was meant for suspending a triangle.

This is so impressive, Brad! Thanks for sharing this with us, you guys.

Does that dependent wrap have any tuning?  Can't see where it slides.

I believe it's in the back, behind the majority of the wrap.

Judging from the bracing and the tubing sizes, I'd guess that that loop in the very back can be pulled out.

I have a new idea for a contra: design the bell section with three valves and a screw-on leadpipe.  Then produce a valve alternative for the handslide and you have the ultimate doublers tool for unusual low brass parts: a contra, cimbasso, euphonium.

I get the cimbasso and contra part, but how could you possibly get a euph out of that equation? No matter what you put onto the bell section, it will be in BBb. Unless, that is, you were to shorten the bell section significantly (meaning the contra slide had to be way longer) so that one could simply attach a short tube and keep the horn in (tenor) Bb. However, this instrument would be ridiculously unbalanced/back-heavy and the valve tubing in the bell section would be twice as long as needed for a Bb euphonium. So once again, how would you get a euphonium out of it?

Rework the bell section with three standard valves, or four, don't use the slide, stick a mouthpiece lead pipe where the slide usually goes, and it might come out close to Bb.

And I never said it would be ergonomic.  It was a joke.
