Yeah, that doesn't look like it's written for piano.
You can stick to exactly what's written. That would keep the line in tact.
You can switch the hand that plays it. The right hand is already right there.
Do a two note roll from the bass note up with the left hand so you can hit both notes. Not at the same time, but almost.
That horn 2 part has its first two 8ths crossing the bar. Might be the pdf conversion, but it might also be someone who does quite know how to use Finale. Looks like Finale to me.
Depends what the performance situation is. For myself, I'd make it so I could play it, and play it easily, and make it sound good. Whatever I have to do to make that happen.
You can switch the note up/down an octave. That will mess up the line, but make it much more playable.
Same idea of shifting it... Trade notes with another chord note in the other hand. Again, messes up the lines, but it keeps all the notes of the chord in tact.
You can leave out the fifth of the chord too and sometimes squeeze a note in around there.
Or leave an inner line out. Soprano, bass, and the chord. People aren't going to miss an inner line so much.
Who knows how this music was arranged. Probably sticking to exactly what was in the original score. That arrangment doesn't look exactly keyboard friendly. (Hopes it's not Bach's original now.) Even still, that's not quite friendly with the intervals there.
I would just rewrite it a little and make it work and sound as good as possible. The nice thing about that is you can make it tailored to you and how much acrobatics you want to do.
With scanning technology today, who knows how that was put together? It's possible someone slapped it on the computer, punched in what instruments it's for, and then the computer did the rest -- Ignoring the hand issues for pianists.
Hmmm.. Horn parts are in C. You can probably safely leave that 1st horn line out if the horn is playing it. It's just doubled in the keyboard part. No one will miss that.
Valves are 1830-ish. Although... I think those horn notes might be possible without changing valves.... Maybe. Just notes in the overtone series.
I would guess that's a Greentree arrangment since it says Harmonized by Bach. Probably arranged by Greentree, who isn't Bach, so you can rearrange her stuff.
