He composed around thirty theatre shows of most types - operettas (such as Decameron Nights), ballets (like My Lady Dragon Fly), incidental music, revues (annual revues Round the Map and The Passing Show were especially popular), plus songs, "mood music" for the silent cinema and many light orchestral pieces - suites such as Vive La Danse and Marie Antoinette, marches such as Pageant March, Guards Parade March, Splendour and Victory and the individual genre movements Dancing Daffodils, Dignity and Impudence, Land of Roses, Penguin Parade and Queen of the Flowers.

In 1911 the Palace Girls performed a song and dance number, which was originally called "Tonight", but became hugely popular as a romantic instrumental piece "In The Shadows".

It was performed in The Passing Show of 1914 by the popular Basil Hallam, who became Captain B. H. Radford and died in 1916 when his parachute failed to open.

[8] The Divine Art Recordings Group (UK and USA) released on its Diversions label, in February 2012, the first CD album dedicated to the music of Herman Finck, performed by the orchestra and principals of the Bel-Etage Theatre from Estonia, conducted by Mart Sander.

In addition to Finck's most popular tunes "Gilbert the Filbert" and "In The Shadows" (vocal version), this CD also includes several popular dances, patriotic World War I songs and hits from the revues and musicals, as well as two full orchestral suites - My Lady Dragonfly and the magnificently symphonic Decameron Nights, which had not had a revival since 1923.
