Musical Link 1: Melody

Piece I: Melodic Contour
Example 1:
By looking at the score for Piece I, we can see a visual representation of the piece's melodic contour. The piece contains as melody that's often conjunct, even using major scales at times, but also contains sections of melody that are significantly more disjunct. 

Example 2: 
Conjunct Melody 
Disjunct Melody

Piece II: The instrumentation of the piece could affect the listener's perception of the melody's intervals, as it's much easier to hear the intervals when there is no flurry of notes between each of the loudest pitches. In the audio example (Example 3), the first section highlights the intervals with a fewer number of notes being played, and the percussion instruments playing in unison. In the second example, it sounds like the melody is more conjunct than the first section due to the melody progressing more step-wise, and the instruments staggering the notes (rather than playing in unison). The first section also highlights another example of theme and variation, but with more evidence to suggest melodic variation.
