1. Yiri Analysis

2. Overview In the set work there are 3 clear strands or ideas. 1. The balaphone ostinati. (When layered together form a complex polyphonic texture. 2. The drum ostinati (1 bar repeated pattern) 3. The vocal line (Based on pentatonic scale with simple call and response structure)

3. Intro 0’00 – 0’:18 In free tempo High improvised balaphone solo Monophonic texture Trills or rolls on some notes. Establishes key of Gb

4. Section 1 (0’18 – 0’34) Second balaphone joins mainly playing in octaves. Strong rhythmic feel based on 2 bar phrase. Heterophonic texture as Balaphone 2 plays a decorated version of balaphone 1

5. Section 2 (0’34 – 1’09) 3 Drums enter. Occasional djembe fills Melody includes syncopated rhythms

6. Section 4 Chorus A1 Voices enter in UNISON Melody short, no harmony.
