The climbing becomes more intensive with the entire violin section joining, and the timpani rapidly hammering.

The two-bar melody which is used for the sequential climbing is the same melody which closed the second theme. Listen to bar 75 and compare the two passages
Instead of beginning with an ascending step here, Beethoven reverses the melody and begins it with a downward step, played
legato. Alternatively, the upward step is played staccato, giving greater impetus to the climbing drive.
