It does seem that the isolated/bare duration notation crept in
somewhat under the radar, and it's no surprise to me if newbies
confuse the issue. If Ties & Slurs don't grab your attention in
the Learning Manual, you might miss the issue altogether. (I don't
think there's an example in the LM where an isolated duration does
not follow a tie.)

I think the isolated duration syntax should be mentioned as soon as
durations are (like in the NR), ie just before the Rests section on
page 7 (in version 2.26.0). Also it should include mention there
the fact that a space (even a newline) between a pitch and a duration
does not isolate that duration and make it a separate note. The pitch
will search ahead for a duration unless something else intervenes.

BTW, LM uses the terminology "bare" whereas NR uses "isolated",
exclusively.

(Sorry not to notice your post earlier,
which didn't get threaded onto the OP's.)
