This is a book to help you learn to play the piano. It is not a 'Learn the Piano in Ten Easy Lessons' tutor - plenty of those exist - but an adventure introducing you to the world of music and stirring your imagination. Beginning with simple pieces, as you are fed with more knowledge the compositions become more advanced. They are all by composers whose works range from a 14th century Venetian dance to a 20th century South American tango. Your journey takes you through sixty-eight pieces with their historical and geographical backgrounds, the last being the much-loved first movement of Beethoven's Moonlight Sonata. Hence the title.
