Towards the end of the 18th century, Clementi increasingly advocated the piano as the successor to the harpsichord. He composed expressly for the new instrument and in 1801 published a piano school. His interest in teaching is also shown by the “Six progressive Sonatinas” op.36 – six sonatinas in ascending order of difficulty, which are still extremely popular with today's piano teachers. Our Urtext edition follows the long established practice of using the musical text of the first edition from 1797. Clementi's original fingering, which is surprisingly modern, has been included throughout the work.
