The collection of twenty pieces from Köchel Verzeichnis (K.V.) 1-15 is based on Albert Edition 516, 1979, edited by Warren Thomson. Quoth: "The student will find that these charming pieces provide an introduction to the keyboard music of the Viennese Classical Period and to the sonatinas and sonatas of Mozart in particular." There is also a very thorough write-up at the Naxos (God bless 'em) site: and here: . The title of this collection in English is The London (Chelsea) Notebook or sometimes -better- Sketchbook; the German title is usually Londoner Skizzenbuch, 43 Stücke für Cembalo. Some of the pieces are fragments or unfinished. The MIDI Cembalo voice in the soundfont I use (Merlin GM Pro V6.0) is not very good, so I used mainly Grand Piano instead. I hope that the use of other instruments follows in an obvious way from the nature of the respective composition. K.V.15h Kontretanz (Contre Danse, Counter Dance) starts as a simple peasants' dance in the form of a canon. The middle part, however, with its mode shift, melody line and harmonies seems closer to J.S.Bach than to your average band of farmers. I couldn't use repeat marks for the middle part with MOZART because the second time should be piano, so I pasted it with changed dynamics. The D.C. al fine is not in the Albert Edition, but MOZART doesn't play the repeat of the first part in this case, which is just as it should be. Also not the use of a hard line feed at the end of the first part. Michael Bednarek http://mbednarek.com/
