This evening has been very interesting. Met with a local trumpet player who I got in contact with for a baroque trumpet (Music History project). I now have two baroque trumpets in my possession (strangest danged things I've ever played, lol).
He is a pretty big collector, though his thing is specialty horns (Schertzer rotary picc, Schilke Bb/A picc, G large bell picc, Benge Eb, among his collection of era horns, haha). I brought my collection along for some jamming.
He was amazed with the Inderbinen, and of the hour and half we played, he spent the ENTIRETY on the Inderbinen, continually playing against his Bach and pelting with questions like "Does this sound dark enough to you?" and "Man, wonder how they get the bell so solid?"
He noted something I hadn't discovered yet on this horn: The intonation is about as good as it can be. Even the alternate fingerings seem to want to lock! He was especially amazed by that.
I will not continue with my thoughts until tomorrow, just wanted to update. I DO like the horn better with a 5B piece...
