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.15oo is a very short piece full of contrasts. A light piano theme in Eb quavers is followed by five forte crotchet chords in Bb, although both themes are falling. The introduction and development of the themes is separated by a general pause of two crotchets, the only such pause in any of these pieces (Albert Edition). The development of the first theme contains an echo in the left hand, and finally the second theme appears in the original scale of Eb. There are no repeat signs.
