I decided to go back and revisit some of the Sor studies Segovia compiled.
Number 10 is Sor's Opus 31 no. 19. I decided to look back at original sources and I have a facsimile of the Meissonnier publication (1st edition?). In this version, m. 15 ends with an 8th note rest- i.e., no 32nds at all on the final upbeat. Segovia has four Bs there and that's how I've heard everyone play it.
I also have David Tannenbaum's The Essential Studies volume of commentary on the series and he makes no mention of the missing notes. He does reference N. Coste's version of the piece, but I have not been able to find that. Tannenbaum seems to think that, in general, Segovia may have worked from Coste's edition.
So.... anybody have Coste? Opinions on whether the missing notes are missing or intended silence?
