For the record, my Rosh Hayeshiva did NOT view classical music as klipah. he said that despite the objectionable behavior of the composers, when they composed they were inspired.
Playing an instrument is time-consuming versus singing along with a cd. The Orchos Taddikim (shaar ha’ahava) recommends singing to develop dveikus and love with Hashem. He doesn’t say a word about playing an instrument.
Maybe Breslov writing say otherwise, but I’m not a Breslover.
