A lady asked me what a strange instrument was that she had seen in an orchestra. It was very like a valved trombone but sat upright in front of the player with the bell at the top and pointing forward. Now I had seen one of these at a Tuba and Euphonium symposium several years ago at the RNCM Manchester, so I could tell her what it was. Except that my memory went off line and the name escapes me completely. Can any body help please. I remember that it was Italian and only scored for in a handful of operas which ties in with where it was seen and I do remember that it was very loud when played.
