This is the Scherzo from Haydn's piano sonata Hob.XVI:9 in F; this sonata is mostly called Piano Sonata No.3, but also sometimes No.9. The Scherzo is the third movement and not the fourth, as some souces call it, because the Menuet and Trio together form the second. June 2007, Michael Bednarek mb@mbednarek.com
