Composers vs Engravers: Stems and Slurs part 2
Posted: 15 Nov 2016, 22:26
Another "questionable" spot from the German 1st edition of Chopin's Etude op.10 no . 4:
1. Why is there no slur in the LH of measure 4 when there were slurs over the same music in the LH of measures 1-3?
2. Why does the slur in measures 5-6 start where it does? No one would expect this.
2. Why the up-stemmed notes in the LH on beat 3 of measure 5?
I think that attempting to answer these questions can tell us something about notation and engraving during Chopin's time.
Answers:
1. Slurs in the Classical canon mean legato and legato only; they do not show musical phrases ("phrasing".) except when a phrase happens to be the same as a legato area. And in piano music, a single slur was often used to show legato in both hands, particularly when both hands are playing on the same staff. This explains the absence of the LH slur in 4-5. The slur over the upper staff takes care of both hands.
2. Chopin intended the LH 16ths in measures 4-6 to form one long legato run. The LH slur in 5 simply continues from where the RH slur leaves off. It is actually possible that in the original fair copy, which has been lost, a single large S-shaped slur combined both of these slurs. S-shaped slurs sometimes appear even in runs on a single staff in the MS of various composers of the time.
3. There is a melodic motive G#-A-G# that runs through measures 4-7. One sees it several times in both hands starred in the example above. The large stars show the motive in the LH run in measure 5-6. Each of the three groups of eighth 16th-notes in this run represents a single note in the motive. Chopin used stem direction to show this structure. Any other stemming would have worked again the unity of the whole motive or its constituent parts. The stemming is exactly like this in the composer's MS sketch.
One notes that Chopin actually had to change stem direction on beat 3 of measure 5 to produce the nonstandard stemming. It would have been easier for him (and more standard as well) to have continued the down stems from the upper staff.
