Mozart called his Sonata K 545 Eine kleine Klavier-Sonate fur Anfanger(A little clavier sonata for beginners) when he entered the theme in th e catalogue of his works on June 26, 1788. The Sonata is usually known as the Sonata facile, and it is considered easy to play, ideal for teaching purposes. While this is true, we must bear in mind that Mozart, like Bach and Schumann, maintained the highest standards when writing for students. The third movement, a Rondo, is perhaps the most child-like movement, and the innocently graceful G major Andante is based on a resourceful use of Alberti patterns. Despite its apparent simplicity this movement shows a surprising depth of emotion, especially in the second episode which turns into the minor key.
