Adams Sonic with 5th Valve

[ann reid]

Any opinions about the ADAMS 5 Valve that has appeared on FaceBook and Instagram today?

Wondering if this would be the compromise horn I’ve been wondering about?

Hi Ann, could you post links to the instagram and facebook pages where you found this Adams 5-valver?

Best, Guido

What about this innovative 5th-valve-euphonium we built for Matthew Summers?
The extra rotary valve assures tuning like a bass trombone Gb valve.

Matthew is just now retiring from the Marine Band. Here are the photos:

Hi all,

Matthew Summers was at the Adams factory at the same time I was last summer to drop off my E3 for its modifications. He was in deep discussion with Miel Adams (which I was able to observe and lightly participate in) about this very horn. The idea to graft in a Gb attachment on a rotary valve between the 3rd valve and the 4th valve on a non-compensating Sonic was discussed and mocked up there. Miel Adams had an "in-process" Sonic dismantled and a rotary F attachment housing mocked up in the short distance available to make the Gb attachment be independent as it would be on most Bass Trombones. Matt's motivation was not only to have this unique instrument mirror the playing characteristics of the bass trombone he plays when not in the Marine Corp Band, but also to reduce valve mass (by eliminating extra inch of length on 1-2-3) and to make the horn more free blowing. Plus he now can get down to a real double pedal Bb.

It is great to see this horn now and Matt will be playing it at the US Army Band Tuba and Euphonium Conference (Workshop?) in a few short weeks. While not an entirely new idea, Matt is trying to eliminate the weight of valve action on 1-2-3 and make a free blowing horn that has great low range response while using the options available with the 5 valve combinations to deal with the inherent intonation issues.

While I am not sure this will be widely accepted, I am sure he will make the most of this unique horn.

I think I would like it. I could never afford one, but I do believe I would like it.

Do you have any idea of what fingerings would be used?

[daruby]

The 5th valve is equivalent to a 2-3 combo. I am completely in the dark how one would use it, but if I played bass trombone, it would be more apparent.

I think we can infer some fingerings. The extra slide is roughly the same as 23, which is a half step shorter than the 4th valve slide. So I might assume that if I need 234 for a low concert D on a non comp, then I might need 13+rotor with the new system. Some similar math might yield a clue or two.

Now this is interesting. Doug, do you say this was fabricated with the Sonic model, a non-compensating horn? Looks like it from Dave's pictures.

On a trombone with an F attachment, the trigger gives you an F and if you want an Eb below the staff, then you use trigger and 1st position, but it is a long 1st position! On a bass trombone with two triggers, the second trigger usually causes you to move the slide positions even further out for various notes.

So, with this valve, it seems there would not be a good way to get notes in tune when using the 5th valve with other valves. If the horn were compensated, then it could be better, but maybe not as good as a 4 valve compensating horn.

Or would you just have to use an entirely different set of fingerings when employing the 5th valve? (Like you have to use 234 to get low D on a non-compensating horn, instead of 124 which you would use on a compensating horn.)

Guess I don't quite know how this works. Would be interesting to find out.

It works like a bass trombone with independent F and Gb attachments. The 4th valve is still a non compensated F attachment and the 5th valve is a non-compensated Gb (2-3) attachment. You can use 4 and 5 together also. Lots of optional fingerings. BUT, I don't really know how it works.
