Really? It's clear to me. If the stem direction is indicating the bass line can you explain why the low E and A do not have down-stems?
A misunderstanding. I'm saying that the stem-direction does not
indicate fingering, just the part. Of course, Carulli is free to do it differently as long as he explains.
Did you not read Carulli's explicit direction? The extra (down) stem only indicates that the note should be played by the thumb. I'm sorry, but if you are translating his words in some other way then we are at an impasse.
Is this about that extract? It's up to Carulli. He had to explain because it's not normal use stems to indicate this.
As to Sor - if he was performing Carulli's little waltz I am sure that he would have used his thumb to execute those same notes with or without an instruction, but not because they constitute a bass-line - rather that they fall comfortably under that digit according to his technical principles as outlined in the quotes presented by Bellydoc.
Any normal player would play the bass line with their thumb even though two of the notes shown have no down stems. By your reckoning the low E and A would have to be played with the fingers. if I was told nothing else I'd assume the two inner notes with down-stems are part of the bassline, as the stems indicate, and also the low E and A.
In the end we will all take our own paths. I'll continue to involve my thumb for some secondary voices and accompaniment roles when performing Sor's works; it suits me well and I believe it to be the approach described by the man himself.
Fine. It seems like the correct approach to me.
