Theatre and music An amphitheatre known as the Rose Bowl was built largely by pupils and masters in two years during the 1930s and underwent a major structural change in 2009. It can seat up to 2,000 people and has been the setting for numerous plays as well as musical performances and speeches during school ceremonies such as Founder's Day. The Multi-Purpose Hall is a more modern indoor theatre that can accommodate approximately 2,000 people. Plays are regularly staged in English and Hindi, with 8–9 productions each year including 2 major productions, which usually have a larger cast and budget, as part of the Founder's Day celebrations. The Inter House Once-Act Play competition is held each year, alternatively in English and Hindi. The stage design, sound design, stage lighting, and much of the set construction are the responsibility of the pupils. In 2001, a new music school was built beside the Rose Bowl. It houses a music library, a concert hall and several practice and teaching rooms where students learn various western and Indian instruments. Pupils of the school have an option to appear for the Trinity Guildhall music examinations, conducted by Trinity College London, in piano, violin, drums and classical guitar. In 2002, the school choir raised 2 million for victims of the 2001 Gujarat earthquake by organising a charity concert with the title Concerto 2000, in which drummer Sivamani also took part. To commemorate its 75th Founder's Day in 2010, the school launched a music album, called Spirit of Doon in collaboration with EMI. The tracks were written by the lyricist Gulzar and were sung by the school choir, Sonu Nigam, Shayan Italia and Bhajan Sopori. Affiliations and partnerships From its foundation in 1937 until the early 1980s, Welham Boys' School was a feeder school for Doon School and Mayo College. This ended when Surendra Kandhari, an old boy and former housemaster at Doon, became principal of Welham and transformed it into a high school. Families who send their sons to Doon often send their daughters to Welham Girls' School, and many Doon alumni have married alumnae of Welham. The two schools hold an annual "dance social", and their alumni sometimes collaborate in organising events. Pakistani ex-pupils from Doon established the Chand Bagh School 40 km north of Lahore, Pakistan, in 1998, modelling it on the general structure of Doon.
