I also used these realistic sounds in a psychological way. With The Good, the Bad and the Ugly, I used animal sounds - as you say, the coyote sound - so the sound of the animal became the main theme of the movie.
My more risky or avant garde music is not that well known to a wider audience, but I wish it was.
I was offered a free villa in Hollywood, but I said no thank you, I prefer to live in Italy.
I was born in 1928, so in 1943, 1944, we had the war in Rome. There were a lot of hardships, a lack of food, many shortages. So when I worked with the Americans, the English, and the Canadians soon after the war, when I played with them, they paid me with food. That will give you an idea how widespread poverty was at that time.
If you scroll through all the movies I've worked on, you can understand how I was a specialist in westerns, love stories, political movies, action thrillers, horror movies, and so on. So in other words, I'm no specialist, because I've done everything. I'm a specialist in music.
Some movies work really well with music from Bach or Mahler that existed long before the film, so music has its own autonomy.
