passage: Modern Symphony Orchestra
The Modern Symphony Orchestra was founded by Arthur Dennington, who led several smaller orchestral amateur ensembles in Northern London at that time and combined them in 1931 into a symphony orchestra. The name "Modern Symphony Orchestra" derived from the fact that the orchestra wanted to play "modern" music by contemporary and little known composers, and allow young soloists to perform with the orchestra.
