First of all, it says a lot of positive things about your teacher, that he came up with a way to bring in the violin part for working on this piece. Is this the same teacher you wrote about who will be leaving soon? He sounds amazing.
I'm somewhat familiar with melodica because when it was mentioned somewhere, I looked it up then. I did a search now out of curiosity of whether there are also some serious performances with the instrument. I'm thinking about the humble descant recorder which are handed out to school kids as plastic versions, and they come home home emitting these awful squeaky sounds, but it can be something else. I just discovered this amazing musician. Listen to what he does with breath and nuance as the music goes on. It's enhanced by the miking and reverb in the room, of course. There is another video in an ordinary outdoor setting where he explains the kinds of sounds he can create, and the melodica doesn't have the kind of resonance of sophisticated instruments.
If anyone is as interested as I was, in this video he discusses the types of sounds he can produce. He played it everywhere while waiting to get into Juilliard.
