Similarity #4: Rhythm

Another similarity between these two works is a rhythmic motif used in both pieces. Because of the difference in time signature, the values of the notes are not the same, however, the result, the rhythmic motif, sounds the same.
This rhythmic motif is formed by one note and two succeeding notes of half the previous note’s value. For example, this theme first played by the horns in rehearsal 25 of Rite of Spring uses this rhythmic motif:

Extract from Rite of Spring - Rehearsal 25

Where this rhythmic motif is used in the Mongolian Idyll is in the first theme:

Extract from Mongolian Idyll - b. 5-8

Another similarity is the use of dotted rhythms, which can be seen in both the extract from Rite of Spring and the Mongolian Idyll.

This rhythmic motif and the dotted notes in the themes are reminiscent of rural folk song melodies, since they reflect dance-like movement and energy.
