Poetry

Unusually for 20th century novels, the prose narrative is supplemented throughout by over 60 pieces of poetry. These include verse and songs of many genres: for wandering, marching to war, drinking, and having a bath; narrating ancient myths, riddles, prophecies, and magical incantations; and of praise and lament (elegy). Some, such as riddles, charms, elegies, and narrating heroic actions are found in Old English poetry. Scholars have stated that the poetry is essential for the fiction to work aesthetically and thematically, as it adds information not given in the prose, and it brings out characters and their backgrounds. The poetry has been judged to be of high technical skill, reflected in Tolkien's prose; for instance, he wrote much of Tom Bombadil 's speech in metre.
