Covering, adapting, arranging, transcribing… these seem like something exclusive to modern culture. But music has been adapted, rearranged and reworked throughout classical music history. During this Deep Listening Day, musical metamorphoses mislead your ears. You will hear well-known jazz standards in a quarter-tone style, grand Wagner arias and overtures on piano, or the age-old cantus firmus technique breathing new life into old music. Composer Karel Goeyvaerts also wove his way through stylistic extremes like a musical chameleon. Or is that just how it seems? Is there actually a homogeneous compositional oeuvre hiding behind these superficial transformations? Fine-tune your ears.
