about

This piece is based on sonification, turning data into sound. In the same way that people turn data into pictures (a simple example would be a graph) to better understand that data rather than staring at a table of numbers, data can also be turned into sound to gain insights. This particular piece was created by five species of Yellow Underwing moths (Nocta species). I run a catch and release moth programme at home, I took the 2019 data from the nightly catches and assigned the number of moths caught to the appropriate note in a scale (ie higher moths resulted in a higher pitch), while the timing relates to the date of the catch. It starts with a single species and then repeats as further species are added represented by a different instrument. There is a short section using the grandest instrumentation which represents the data for the Least Yellow Underwing which made the fewest visits. I made a very few “musical decisions” in removing a couple of days where I didn’t run the trapping programme. No moths were harmed in the production of this track.
Thanks to the Electronic Music Philosophy group and in particular “Skoddie Autumn Altair” for setting the challenge that led to the creation of this track (I had to look up Sonification). To hear some “proper” experimental music go here: electronicmusicphilosophy.bandcamp.com
