It's called the bull horn because we got the horn from a real live bull
First my dad and I went to a farm and got the horn then my dad helped me by drilling the holes in the horn.
Then my dad got me a trumpet piece. I put string through the holes.Then I glued the trumpet piece to the horn.
For dynamics to make it loud by blowing harder into it,to make it soft you blow into it the horn softer.
For pitch you tighten your lips for high. And you untighten your lips a little bit for low. The timbre is loud and buzzing.
