Katherine K. Davis (1892–1980) composed "The Little Drummer Boy" with Henry Onorati and Harry Simeone, creating one of the most enduring modern Christmas carols. Davis was a prolific composer of sacred and secular choral music, with particular strength in writing accessible pieces for church choirs and school ensembles. Her gift for melody and her understanding of what voices could accomplish at various levels made her work staple repertoire across American choirs for decades.
Davis's approach to composition prioritized singability and emotional directness. "The Little Drummer Boy" exemplifies these qualities: the tune is memorable without being simplistic, the harmonic language is warm and clear, and the narrative arc engages singers and audiences alike. Her legacy includes hundreds of published works, many of which remain in active performance.
