There is a leap in measure 11 oboe line. What are the 2 notes involved in this leap? explain

Question

G to D
F to C
E to B
C to G

Answer 1

In measure 11, the oboe line includes a leap of a fourth from G to D. This means that the oboe jumps from the note G, which is four diatonic steps above the starting note, to the note D.

Similarly, the oboe line also has leaps of a fourth in other parts of the measure. It leaps from F to C, E to B, and C to G. In each case, the oboe is jumping up by four diatonic steps on the musical scale.
