The sound of aluminum or steel cans (typically the size of dog food cans) being struck for use in some types of Hi-NRG music. Created by either computer software synthesis or synthesizer hardware synthesis.
No actual cans are struck or damaged when synthetic cans are used.
The song, "EURODISCO 'New Hi-NRG' (2012)" has the sound of synthetic cans; you may also hear synthetic birds in it.
