Hello there...
Forgive me for being new and jumping straight into pedants' corner here, but I thought a "Baryton" was a rather unique kind of string instrument, rather than the "Baritone" I play...?
Baryton being a wonderfully odd instrument composed for and played by Haydn, which had strings like a violin, and sympathetic strings behind which could resonate sympathetically (!) or be plucked by the left hand which hid round the back of the instrument. And with this specific spelling, which a lovely little onomastic legend attributes to it being the cause of a "parydon" or pardon to a Frenchman by Charles the Ist; since when it has been called "the king of instruments, and the instrument of kings."

My Baritone is a baritone saxhorn, invented by that nice mr. Adolphe Sax as the lowest instrument in the saxhorn family, which consists of what I've always called tenor horns. Not a direct descendant of the euphonium, which really is a tenor tuba...

Maybe I'm barking completely up the wrong tree... or maybe I need to get a life Thoughts welcome!
