String of Yeasts 2020

The Sourdough Project data is finally starting to sing!! The paper, The function and diversity of sourdough microbiomes, is on the verge of being published and I have completed 3 pieces for an album of soundscapes based on the data and findings of the paper.

A little over a year ago, I started working with the Optical Density growth patterns of the 8 most prominent taxa in the 500 starters. Here is a link to the blog post about this idea:

Recently I revised the scale to be a multi-octave expansive scale and aligned the 40 specific growth data points with notes on that scale. Each yeast and LAB (lactic acid bacteria) now is expressed as a multi-octave pentatonic pattern. Here is the final version of String of Yeasts which will introduce the four yeast voices on the album RISE:Sonic Sketches of Sourdough Cultures to be released in March 2021. This piece features K Servazzi, W Anomalus, K Humilis, and S Cerevisiae.

    • Thanks! I am excited with how the pieces are coming along. Still thnking about In C and the ways those patterns worked with and against each other as a kind of larger framework. So far it seems to be working. I am interested in what you and Susanne think/hear in them. Trudie is creating gorgeous alcohol ink watercolors in response to the sketches!
