New Intonation Charts

[davewerden]

I just came back from a conference and was able to do some new tuning runs. You will find new/updated info for:

Adams E1
Adams E2
Adams E3
Besson 2052-2
Eastman 826

They are all here:

For what it's worth, I'll put here the pitch graph of my 2007 Prestige, obtained in the same way as described by Dave. (mouthpiece K&G 3D +). As you can see, there are some high notes, especially the partial 6th, which can be easily adjusted with the trigger and practically no low notes (except for the central A of only 5 cents easily corrected with the lip). Compared to Dave's it's quite different.

Thanks for the 2052 comparison! Results will vary with the player and mouthpiece, of course. I should have mentioned that the room these horns were in was pretty cold, which could also affect things. My process includes warming up the horn and getting a little bit used to it before I start charting, but it could still have an effect. However, the graph from the 2051 has some similar characteristics, and that was made 8 years ago in a comfortable room.

It's also possible that the 2007 production is different from today's. I noticed the Adams E1 is different from my former E1 (made in 2012). I'm starting now to note the year on that page as I get newer readings.

That 2052-2 chart is pretty consistent with what my horn does, with the exception of the concert G.

FYI, according to my notes I used 3rd for the concert G.

Ah, that makes sense!

Idem.

This is the pitch graph of my 1974 Besson New Standard, obtained with pitch A = 442, main slide extracted of 13 mm and 1th slide of 10 mm. The notes E 5th staff and F above the staff have been obtained with 1-2-3 and 1-3 respectively, the dashed line indicates the pitch with the normal positions 2 and 0. ( Modified K&G T3D mouthpiece)

franz,

Thanks for the graph of your NS. I had one that was a couple years older than yours, and it tuned easily to A440. Was yours built in high pitch? Just curious.

Frankly, I don't know. Now the air temperature is around 25 degrees celsius, I got the graph after a good half hour - 3/4 hour of warming up. I tune with A = 442 because it is the pitch with which we tune the band. The 13mm extraction of the main slide seems to me a fairly normal size, considering the fact that I used a modified K&G T3D mouthpiece (suitable for trombone) (wider cup and deep V profile) whose shank fits into the receiver for 35mm.
