The trip took Iona Thomas-Wright (harpist) and Lisa Riedel (drummer) to the Polish city of Kraków and saw them perform four concerts in five days.
The pupils travelled to the city on Sunday, June 11 for a five-day concert tour.
Traditionally, the music department undertakes an overseas concert tour every second year, with recent destinations including Germany, Austria, Hungary, and the USA.
The 37-strong group formed as an orchestra, choir, string ensemble, concert band, ceilidh band and various other chamber groups.
Mr Parfitt, Director of Music at St Margaret’s School for Girls, said: “The girls worked extremely hard to perfect their performances for the Poland trip.
“During our five-day trip they performed at Redemptoris Church, XXVIII High School, St Peter and St Paul’s Church in the Old Town and at an outdoor concert in the Market Square.
“The city is steeped in history and culture and the girls also enjoyed some time to explore the city as well as performing to the people of Krakow.”
Head Anna Tomlinson said: “Music is held in high esteem at St Margaret’s, both by our pupils and by our staff, and the school is acknowledged throughout the city and region as a place of musical excellence.”
She added: “All girls are encouraged to acquire choral and instrumental skills and to enjoy participating in the school’s various bands, choirs and orchestras.
“Our girls represented our school and city in the best possible way and we are very proud of them.”
