Goat/Copper Horn Customization

I love the horns so far and they're a really cool feature for socialization and whatnot.. However, I feel there's some more potential for it. Using a block similar to a Smithing table, you could customize the notes (maybe max of, say, 16?) All in an order that'd play one after another. By dragging up the pitch on a specific note or changing tempo, you could make your own mini war sounds. Then, when you sound your horn, it'll make your small tune play. It might be a bit difficult to make, but it's just something I think would be appreciated by everyone, as simple(?) as it is. If this were added, I could see having a ton of fun and funny moments with this on SMPs.
