Where these songs come from

Now Is the Month of Maying is Thomas Morley's dancing May song, a ballett with "fa la" refrains, printed in London in 1595 for five voices. Ave verum corpus is Mozart's short Latin motet, K. 618, which he dated 17 June 1791, the last year of his life. Brahms's Lullaby is Johannes Brahms's Wiegenlied, Op. 49 No. 4, written in 1868 for a friend's newborn son and sung here in Arthur Westbrook's English of 1901. With Cat-like Tread is the pirates' chorus from Gilbert and Sullivan's The Pirates of Penzance, premiered in New York in 1879, and The Lord Bless You and Keep You is Peter C. Lutkin's choral blessing of 1900, ending in a sevenfold Amen.

Every song here is public domain, and most keep their composer's own voice parts: Mozart's four as he wrote them, Morley's five as four, with his two tenors joined, and Sullivan's and Lutkin's, adapted by us. Brahms wrote his lullaby for one voice and piano, so its parts are our own arrangement on his piano harmony. Each card says its key and how hard it is. Play a song's first line to hear every part together, then open your part to hear it alone or with the others under it, and sing along as each note lights up. Each song's page tells its story.
