Sorry for the hiatus. I finally got around to looking into the scanned images provided by Kroket and I found some interesting information. Bear in mind, I used Google Translate to roughly translate the scans from German to English so the translation is not perfect. If anyone speaks german, help would be appreciated!
Ecossaise in E-flat Major:
Excerpt from the scans: "Ich hatte auch einige Ecossaisen, von denen eine so anfing: Turczynowicz (siehe Lit.) hält es zwar für möglich, daß es sich hier um den Anfang der 2. op72 handelt, es ist aber wahrscheinlicher, daß Kolberg den Anfang einer unveröffentlichten, verlorengegangenen Ecossaise mitteilen wollte"
Rough translation: "'I also had some Ecossaises, of which started as so:' (Refer to incipit). Turczynowicz acknowledges that it is possible that we are dealing the beginning of the 2nd Op 72 No. 3 Ecossaise, but it is more likely that Kolberg wanted to inform the beginning of an unpublished, lost Ecossaise."
The document seems to imply that the Ecossaise is a transcription from memory, and that it is perhaps a misinterpretation of the Ecossaise Op. 72-3 No. 2 as it bears some resemblance to it. If it is a different, lost Ecossaise, and it is a transcription from memory, it is possible this piece was never written down by Chopin.
Mazurka in B-flat Minor KK. Ia/8:
Excerpt from the scans: "Zwei zwölfzeilige Blätter im Album von Walerian Stopnicki, dessen Inhalt in der Zeit zwischen 1867-93 gesammelt wurde. Heute Eigentum von Jan Tomasz Stopnicki"
Rough translation: "Two twelve-line music in the album of Walerian Stop Nicki whose contents were collected in the period between 1867-93 . Today property of Jan Tomasz Stopnicki"
I googled the name and found a phone number for a person by this name on the Norwegian Yellow Pages at the url: http://www.gulesider.no/person/resultat ... +Stopnicki
. I know there are a lot of devoted musical enthusiasts here who locate, and scan rare pieces of music. It would be great if someone could help look into this and possibly contact Mr. Stopnicki!
alfor wrote:unfortunately no further Chopin manuscript of interest. Most of the material is provided with short comments in German, but all longer material like newspaper articles in polish has not been translated!
It seems as though all the scores I have found for this piece are transcriptions of the manuscript. I know its been a while, and you may no longer have the book in your possession, but if you do, would you be able to scan the manuscript itself?
