NOTATIO

Usually string numbers are in Roman numerals (lowest=IV, highest=I). These now look quite like fingering numbers. You could also put a zero (0) on the last note as it is an open string.

Liszt would have used his nose for bassoon notes.

I'd put a tenuto dash on the chord and damp marking (either word or symbol [looks like coda-marking]) on the downbeat.

Or "il arpeggio legato possibile".

Couple comments from ex-bassonist (also a music copyist): The part looks very nice. Somehow it seems like all the dynamics are little too much to the right? And if you want to be nice to the players, you should number the repeated bars (like 16-25). Better yet, change the layout to be more in one wi...

Sorry, I was probably a bit unclear. I meant composer manuscripts, where the "slashed 1/8" quite often was the way expressing 1/16-note. Your example looks engraved, not typeset, so any kind of symbol was of course possible.

At least in Mozart's time, the slash WAS the way of writing a solitary 1/16-note (appoggiatura or not) - see the facsimiles at NME for examples. Same with Rossini and (early) Verdi.

Also "poco f" "molto f" and "ben f" are sometimes used...

I would put it to one clarinet (in A!) and edit the ending note octave up (or something - or give it to bass clarinet). Nested tuplets, yes but also edit slightly: up in 8 1/32's, the down 4 1/32 + 1/16 triplet and 1/16 sextuplet (these all inside a triplet). More practical and certainly easier to p...

I think the double dot (one before and one after the note) indicates a half dot, ie. where a single dot would add half the value, this half dot adds a quarter of the value. Therefore 1 quarter note with this sign becomes a full 5/16 bar. I recently worked on a couple of pieces by the Norwegian comp...
