Woohoo! Db on the money on the first try! Ill need to cut a hair more off so it can be tuned, but thats no issue. I also have to solder up the inner slide/alight it so I can play it in more than first position, but i went through every partial, and its no better/worse than my Bb bass on a tuner.
Initial impressions of the sound of the instrument is the horn is overall a little brighter, which is easy to manipulate with the gauge of the bell material. Also, once i do the screw bell conversion, it may darken up a bit.
It this point, as a Db horn, this is very much a success. Once i have the slide aligned and soldered i will make some quick videos. I think you guys will be surprised at the result. Im not seeing a real need to go further, as at this size it meets all the requirements i have.
Now, since Doug pointed out I cant call it a Contra alto, what do i call it? A Db bass?June 22, 2018 at 9:28 am #4350
Heres a photo with the shortened slide.

I alto forgot to mention, there is a major advantage to Db. With dependent valves it makes sense to go Db/Bb/Gb. This way, there is added utility in two keys the user is alreay familiar with.June 27, 2018 at 11:49 am #4393
What a fascinating discussion. I’m anxious to see how it works out.
I guess we could call this an EEb trombone much like the large bore Eb tuba is called EEb (it’s still the same length as my 1892 3-valve Conn).
Also, I have a Carl Hampe method book where he mentions an E attachment for the trombone (rather than F). This would correspond to an A attachment for the EEb alto. Not sure if this is any better than the Ab attachment but I thought I’d throw it out. Incidentally, in the famous picture of the Boston Symphony brass players of 1921 Mausbach is holding a trombone with an E attachment.

Bruce, been a change, sticking with Db for now.
Heres a size comparison shot. I will be dpong the valbes within a week, goong to do the Db/Bb/Gb setup

I think i lost everyone, but here’s a valve slowly being fitted.

Very interesting Jeff. You should make a video playing the horn with the valve. Maybe play a short excerpt of some bass trombone piece for comparison of the Bb bass and this?
Yup! Im waiting on a perch for the valve lever, then i have a few video comparisions planned. Thinking one exactly how you suggested, one with another bass playing duets, and if i can manage it, one playing in a section. I figure that’ll give a good sampling.July 9, 2018 at 3:13 am #4541
So, to share the latest, the bell section other than the lever perch is complete. I put a nice satin finish on it, no lacquer, as i am not set up to spray at present. With a little attention the valve is now reconditioned to as good if not better than when bach made it, just the tuning in slide to tackle.
I also started planning out the dual valve prototype (yes, I’m making 2 now) and am trying to see if theres a way to make an independent configuration work well. As a stroke of luck i found some parts i had laying around, so i have most if what i need to do it.
Heres a photo of the completed bell.

So I’ve had some guys locally try out the prototype, and ive gotten very positive feedback, so much so that this happened. Just waiting on the tuning slide and bell to solder everything up

It grew a little, and slightly redesigned.

Interesting ideas here. When thinking contra alto trombone. I think on my real old small Eb tuba. A fun little 3 valved horn. The Eb tuba is used in concert bands along with Bbs. Ther are used in brass bands and civil war bands and some brass bands. I know the tubing isn’t the same as the trombone. I’m only trying to thing about marketing a contrabass tronbone, in practical terms. As a player I love the idea. Honestly I don’t know where I could use one. That is not to say you may find a niche. Good luck with your project. Taking a look at little Eb tubas may give you some ideas and a feel for low Eb brass playing and sound. Just a thought. Go for it. And enjoy the process. Learning and creating something new, can’t be a bad thing.
