The collection includes 3 symphonies, 4 operas, 10 choral works, 25 chamber works and numerous piano pieces, part songs and short orchestral pieces, many of which were broadcast by the BBC Midland Light Orchestra during the 1960s. There are over 90 autograph scores, 41 sets of orchestral parts - mostly autograph but some in the hands of copyists, including pupils of Edmunds - together with some photocopies. This makes performance of the symphonies and other orchestral and chamber works a practical possibility. There are also many printed scores, particularly of piano and instrumental music, and a large number of part songs which Edmunds wrote for the choral festival movement of the 1920s and 1930s. Additional items include a tinted photograph of the cast of the opera The Blue Harlequin (performed in 1929 and 1937). A reminder of how composers have to struggle for recognition is revealed in two letters of rejection from publishers, despite complimentary remarks pencilled on one of the scores by the reader.
In Edmunds' day unpublished works were performed straight from the autograph manuscript and some of those in the collection are signed by conductors such as Harold Gray and Julius Harrison, while others bear dedications to David Willcocks and Stanley Adams and the viola player Lena Wood. The collection represents a tangible link with the Bantock tradition in Birmingham.
