Sara Michieletto has performed with top orchestras across Europe during an illustrious career and since 1998 has played in the first violins of the orchestra of the Fenice opera house in Venice.
But more recently the 41-year-old has played for children across the Palestinian territory of the West Bank, in Indian slums and helping street kids and orphans in Indonesia.
Soothing, classical music helps angry, traumatised youths become "emotionally aware", she said, helping them to better channel their anger and frustration.
"In the case of children from disadvantaged backgrounds, this is so important because they have faced a lot of difficult things in the past and trauma," she said.
"Music is a very powerful means of conveying emotions."
Since 2010 the violinist has been working with street children in and around the Indonesian capital Jakarta, a seething metropolis of 10 million people where many live in grinding poverty, as well as other parts of the country.
