First movement, last note
Second bassoon has an E in the staff, so you can tune with that part. However, Clarinet 1 has the B an octave higher (often sharp!). So you need some flexibility with this.
Here are some fingerings to try, especially if you find you are sharp on this note or it sticks out.
Last movement meter changes
In the last movement comes a section that alternates between three to the bar and two to the bar. Meters represented are 2/8, 3/8 and 6/16. In all cases, the duration of each bar is the same and the section is conducted in one.
Thus, it's just a matter of deciding how each bar is divided up.
The writing is confusing at times and maybe not always correctly written.
I've marked in red where the meter changes. Note: at D the figure should be played as two triplets, whereas at F, the figure is written the same, but the grouping must be three to the bar. Listen to a recording and you'll see what I mean.
