Zweers' music has two distinctive traits: its affinity with Dutch folklore, and a Wagnerian style (especially in his second period). For his songs – most written for his wife and former student, the soprano Dora de Leeuw – he used texts of his contemporaries, including Nicolaas Beets (1814-1903) and Jan Jacob Lodewijk ten Cate (1809-1889). In order to succeed in an personal Dutch compositional style, Zweers thought it necessary to use texts written in his own language. In practice, most of the texts he used, were chosen from Dutch literary works. The poetry of Jacques Perk (1859-1881), Hélène Swarth (1859-1941), and later Cornelis Boutens (1870-1943) were a valuable resource for him. For the Wijzangen he used Dutch translations of poems by Rabindranath Tagore (1861-1941). Since Zweers' death, only the three symphonies have remained somewhat known; the rest of his music was soon more or less forgotten.
