Ingá is a fruit from the tree Ingazeira (also known as Ingá) that grows near the margins of rivers in Brazil. This fruit has numerous seeds surrounded by a white pulp. When these seeds fall into the water, they are transported until they reach the edge of the river and eventually develop into new trees. The form of this work is based on this cycle of regeneration. Each seed – represented by a small motivic cell – grows into a full tree (the full ensemble). New seeds will fall from the mature tree, and the cycle repeats itself.
The last section of Ingá is the only moment in which one can hear a harmonic progression. Until here the work has been built solely around the timbres of metal, wood and skin instruments. In this coda, two vibraphones evoke the fluidity of the water that carries the seeds away to their final destination.
