Bowing Articulation Curiosity
This appears in Busoni's Tanzwalzer in the eleventh bar of the third movement:—
The first bar has a slur placed over three notes with the first two to be articulated in staccatos, I am not sure if it suggests a combined-note bowing, where the bow stops short of the staccatos and continues in the same direction, implying:—
However, Del Mar suggests it is 'meaningless and must be a misprint', voiding my beliefs of the previous.
And then, the second bar is considered ungrammatical by the contemporary notation standards; I am now more inclined to think that the first bar peculiarity is the conventional notation during that time. This begets the question: is the first bar articulation really a misprint or an actual combined-note bowing technique (if fortunate, the one described above)?
