“Ah! keep my songs within your heart (The heart that holds the singer too), And never to the world impart The music only meant for you. Nor breathe one word, one tender word aloud, Lest it be heard by the cold-hearted crowd. To sing what only you can hear Will keep my heart in perfect tune; As sings the nightingale, when clear Above her shines the summer moon, And every tone of truthful love that flows Is heard alone by the enraptured rose.”
