I've finally got around to thinking about the introduction to
parallel voices in the Learning Manual - currently sections 3.2.1
and 3.2.2. You'll remember the many discussions about the two
constructs - explicit voices and the \\ construct, and the
final agreement to introduce explicit voices first, reversing the
present order. I'm now minded to remove mention of the \\ construct
from the LM altogether, except for a brief reference to the topic in
the NR. This seems the simplest way of avoiding the confusion that
frequently arises with the current approach.
Before I start merging 3.2.1 and 3.2.2 to do this I'd welcome your
comments.
