Lauridsen's choral compositions, including seven choral cycles and a series of sacred a cappella motets, are featured regularly in concerts worldwide. In particular, O Magnum Mysterium has become very popular in the choral repertoire and now in the Brass world as well.

His musical language is influenced by chant, as well as masters through the ages, such as Josquin, Palestrina, Gesualdo, Monteverdi, Debussy, Ravel, Fauré, and Duruflé.
