Love all the pics!
One thing you may notice as you play the horn is the way it may vibrate in your hands. That, of course, is part of its design concept. At some point I learned that when I'm really supporting the sound (loud or soft) AND have found the center of each pitch I'm playing, the vibration is way more noticeable. I'm pretty sure that when I'm playing this brass instrument correctly, it gives me more feedback in my hands. Kinda neat, actually.
