Koko - Yiri
  1. General Information
    1. - Koko is a group made up of 6 professional musicians. - They come from the country 'Burkina Faso'. - The word 'Yiri' means 'wood'. - The song might be called Yiri because all the instruments heard in it (other than the bell) are made of wood. - Koko performed Yiri from memory and the score was made later by notating the music heard on the recording. This is otherwise known as 'transcription'.
    2. Instrumentation
      1. The following 3 instruments are heard in Koko's 'Yiri': 1) The djembe - a drum that is played with the hands. 2) The Balafon - it's an instrument similar to the xylophone but is made up of wooden bars which are all tuned to different pitches. 3) The Talking Drum - a drum played with a hooked stick. Talking drums can be used to imitate speech by creating different slides and pitches. The musicians also sing and are split into a soloist singer and a chorus.
      2. Structure
        1. The piece is in 3 different sections: - The introduction, in which the Balafon plays a solo using tremolo (very quick repetition of a single note). - The main section which consists of the drums playing an ostinato and a strong clear pulse. Choruses and Balafon solos alternate in this section and in the very middle there is a vocal solo in which call-and-response is used. - The coda, in which a short phrase for Balafon is played 5 times but varied slightly each time. The drum ostinato, first heard in the main section, is interrupted by rests and a bell is sounded to mark the end of the piece.
        2. Melody, Harmony and Tonality
          1. - Yiri is in the key of G♭ Major. - Most of the music is hexatonic (based on a 6 note scale). - The balafons play short patterns that fall from high to low and tend to emphasise the notes G♭ and D♭. - During the choruses, the group sings together and, much like the balofon, they sing short, falling phrases that emphasise the G♭ and D♭ notes.
          2. Rhythm, Metre and Tempo
            1. - The main metre is 4/4, although there are a couple of exceptions. - After the introduction, the rest of the piece stays at a steady pulse. - Syncopation is used frequently throughout, especially in the vocals and balafon parts. - Triplets are used by the vocal soloist. - During one of the vocal solos the balafons create cross-rhythms by playing semi-quavers in groups of 3. - Rhythmic ostinatos are created by the drums and continue throughout the whole piece. The ostinato consists of a quaver and then 2 semi-quavers that are repeated.
            2. Texture and Dynamics
              1. The majority of the piece has a layered texture, however the introduction has a monophonic texture.Occasional heterophonic textures are created, for example, when the two balafons play different versions of the same tune simultaneously. There is very little variation in dynamics in Yiri.
