When a score indicates lines going from one note in part one (in this case Oboe 1 and Oboe 2) to a note in part two in a criss cross style, what playstyle does this seem to be referencing? I can't find any info about this. Basically oboe 1 is playing a note then a line is written from that note down to a note in the Oboe 2 line. obviously they want some kind of note flow between the instruments but what is it exactly? anyone know?
