reviving the series of antiquarian books from my shelves, here are some musical titles I bought from the book stall at the Oxford Music Festival this year:
Giesbert, F.J. (Hrsg.):
Deutsche Volkstänze. Eine Sammlung der schönsten Volkstänze und Reigenlieder für 1 oder 2 Blockflöten oder andere beliebige Melodieinstrumente nach Belieben mit einer Laute. Hefte 1 und 2.
My edition is undated but the internet ventures all sorts of guesses ranging from 1910s to 1940s. The serial numbers 2361 and 2362 are not that far away from the Rohr-Lehn recorder book for schools (2661) which is ancient, but was still in use in the 1970s. In fact, you can still get these from Schott Music today, apparently, but they don't reveal the publication date either. The editor, Franz Julius Giesbert, lived 1896-1972, so that narrows it down a bit ...
Der Flötenmusikant - Volkslieder und Tänze für 1 oder 2 Blockflöten gleicher Stimmung edition Schott, Band I-III.
These are also from Schott, and a different version under the same title is still available today, presumably the three booklets merged into one. My three little books have numbers on the back cover and month of printing, reading:
158 XII.61 on the first two volumes, and then 158 VII.63 on the third.
Funnily enough, Giesbert No 1 also has 158 in the same place (but no date) and No. 2 has the number 33 - I think these numbers specify the lists of other works available, but the dates are still likely to be close to the date of printing, right?
