PSNY · Lei Liang – Mineral Harmonies Book 1 (excerpt)

Program Note

Singing Earth Project (Lei Lab) is about listening to the earth’s own harmonies hidden in rocks. Rocks are made of different minerals that deform at different speeds, with each constituent experiencing time differently. Some rocks from deep within Earth are brought to the surface in a violent eruption at supersonic speed. This extremely rapid transport process preserves the information these rocks record and help us understand the inaccessible regions of the planet.

Each rock is a book of time.

Our team (“Lei Lab,” launched in 2023) developed the idea and technology to use X-ray fluorescence analysis of minerals to trace a series of data points delineating their elemental peaks. These data points are then transformed through software into harmonies that we can hear.

The first rendition of harmonies was created by our “Singing Earth” team (see credit below) in close collaboration with geologist Emily Chin of the Scripps Institution of Oceanography. Each measure consists of notes from one mineral which is indicated on top of the first note of each segment.
