"vingt secondes" is Karlheinz Essl's shortest composition. It lasts only 20 seconds - the guideline for washing one's hands during the COVID-19 pandemic. It was written during the lockdown in the Easter holidays of 2020. Originally written for melodica, this version was performed on an accordion by Dorrit Bauerecker who also made this recording.
Compositionally, the piece expresses a harmonic spread from a single note to three octaves at the end.
