Notes on H337 - Notturno in g minor
Measures 18-20
In measures 18 and 20, looking at the relative height of the notes and the shape of the line, it seems like Hensel first wrote beat 5 as just a B-flat, and then later squeezed in a ledger line and an A underneath it, pushing what was a B-flat up to a D. The Henle edition has this interval as a third (G and B-flat), but the line through the A looks very deliberate, especially in measure 20, so I don’t think it can be a G.
Measure 31-36
Given where the left hand ends in measure 32 (E-flat5), and the location of the chord in measure 36, is it is likely that the left hand was intended to be written an octave higher for measures 34-35.
Measures 80-81
Though the second 16th note in beat 4 of each measure is slightly higher up than the tied 16th note, the ledger line seems to go through the middle of the note—especially in measure 81—so I think these are likely both A-flats (A-flat is missing from measure 80 in the manuscript, but seems like she intended it to be the same as the following measure). The Henle edition writes each of these as B-flat.
