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”
