BM Symphonic

This instrument is a BM Symphonic Alto Horn of unknown vintage, bearing serial number 731417. Architecturally, it is constructed like a miniature euphonium, featuring a layout where the leadpipe feeds directly into the valve block and the main tuning slide is positioned after the valves rather than before them. This distinctive engineering choices helps produce a beautiful, rich, and singing tone, though it does make managing the overall intonation quite tricky for the player.
