Rain Chain begins with clearly defined roles between the two instruments. The left hand establishes a steady rhythmic pattern on the marimba, while the right hand plays on the vibraphone. The inner mallet of the right hand reinforces the groove together with the marimba, centred around an open fifth. The parallel use of the pitch A on both instruments creates a subtle floating quality within this harmonic frame.

Above this rhythmic foundation, sustained tones on the vibraphone form the main thematic layer, contrasting the pulse below. Gradually, isolated “droplet” figures emerge, giving the piece its title.

A contrasting section introduces harmonic shifts and more pronounced melodic movement. After an improvisational passage over the opening pattern, the initial material returns, and the piece fades out through the recurring droplet motif.

The work forms part of the cycle 3 Pieces on 2 Instruments for 1 Player. Duo and trio versions have also been developed.
