NOTATIO

I do like the larger lyric size of the Breitkopf edition. Small text is much harder to read at a glance for me than small music.

Vaughan, so you wouldn't even go so far as to add the missing octaves in Op. 10/3?

Looks like a computer engraving default (perhaps because it's easier to keep the slurs further away and avoid collisions). LilyPond doesn't do it, and I haven't seen it in any well-engraved music of the past. Given the actual purpose of a slur being to connect notes, I see no reason not to place it ...

Also, digital tools seem to have been created by those programmers not particularly familiar with the reasoning behind many traditional engraving practices, which were then thrown out without any real justification. (See: Good contrast between elements, ottava lines, optical boldness of differently ...

I find Baerenreiter's unstylized roman dynamics to be unpractical as they simply don't stand out on the page as "dynamics" to me, as just one example of how this kind of innovation might diminish our ability to easily recognize these symbols.

Re: triplets - John, I follow your logic when it comes to the second example of the E-flat being a structurally different voice than the C and D-flat; this also explains the different division of notes between the staves. However, this doesn't make as much sense in the first example and I fail to se...

I'm not sure how that can be seen as an improvement unless the grace notes are entirely in time and on the beat.

I'm not too familiar with this form of graphic notation, but is there any need for the re-iteration of the notehead at the beginning of each bar? That would definitely contribute to confusion on my part, even with the tie on the diamond notehead.

Although I haven't examined the literature on this point, I find 155a/b to be more intuitive than simply continuing to number straight-through.

Perhaps not Beethoven's exact intention, but would combining the first eighth notehead of that measure with the dotted-half notehead not achieve the same goal of presenting the lower instrument entering without the difficulties of a centered beam? It would also allow said entry to preserve all down-...
