Here’s 15 short samples of two pieces of polystyrene, handled in different ways. Unfortunately, the filenames are in Swedish, so a short dictionary follows here:

frigolit = polystyrene
skrap = scratch
slag = hit
liten = small
tappad = dropped
stor = large
kort = short
lång = long

I hope they’re useful to you. I’ve used them as a basis for a beat in at least one song.

Feel free to request other samples (contact me via my profile). E.g. I play the oboe, nyckelharpa, soprano saxophone, whistles, accordeon, zither, glockenspiel, bombarde.
