This very short piece is one of Carl Philipp Emanuel Bach's best-known pieces; one of three 'solfeggios' written in 1770. It is probably learned by every aspiring pianist, and is sometimes used in examination syllabuses (including ABRSM). Solfeggietto means little study. I have used a public domain edition apparently edited by Hans von Bulow, and have retained his octave doublings. I have included the few notes he suggested in the last bar to give a conventional ending. This piece is played at many different tempi, and always provides a challenge for the player to get the semiquavers even. When played at a prestissimo tempo, it requires well-trained and dextrous fingers.
This work is intended for piano and I incorporated what I believe are accurate baroque articulations and ornaments. It is best played using the "GeneralUser GS.sf2" Soundfont by S. Christian Collins Software (http://www.schristiancollins.com/generaluser.php).
