Homophonic texture.A: 0:00-1:01B: 1:02-2:02- development of A section.C: 2:03-2:39Coda: 2:40- 2:55 (end)
Opening guitar chord in quartal harmony (perfect 4ths in between) Pitch bend in the guitar creates and eerie effect through use of dynamics (p-mf-p) and
a rapid accelerando and rallentando. Second, longer pitch bend extends this effect. Violin 2 part, alternating between D and Eb represents the earth breathing. Overall
contour of melody is moving up and down. High note of harp ostinato sounds sharp and piercing, over the resonant, plucked tone
