Music lovers will enjoy seeing this beautiful picture showing the great master "in his habit as he lived," and following his footsteps on the night when, moved by pity, he was inspired to compose, for a poor blind girl, his immortal "Moonlight Sonata." Wandering one evening, alone, through the streets, his attention was attracted by the notes of one of his own compositions, rendered in a masterly manner, and, upon inquiry, he found that the player was a poor blind girl. Entering the humble home, he found the beautiful musician, the devoted sister of a loving brother, he a mender of shoes, she a pianist, both well-bred, refined and of lofty ideals. Without revealing himself, Beethoven, learning from the fair musician's lips that she was an ardent admirer of his music, moved by the environment and charm of the evening, sat down at the piano and improvised. The beauty of the night, the moonlight, the breathless attention of his hearers, his sympathy, all combined to inspire a masterpiece which thousands have enjoyed since that fateful evening when an accidental turn brought to life the "Moonlight Sonata."
