I'm reminded that All Instruments of the Bards had the capability of storing spells. B💛esꦰides the specific spells that each individual instrument could hold, a bard playing any one such instrument could invoke the spells fly, invisibility, levitate, and protection from evil and good, once a day, until the next dawn.

A bard playing an Ollamh h🐈arp could invoke the spells confusio𒀰n, control weather and fire storm each once a day, until the instrument recharged its magic at the next dawn.

Any character who spent a king's ransom in research, and a few years time, could find a way to enjoin more than one instrument, such as a 26 string guitar, or the like, with more magic than the above. The danger was in creating something that attracted the attention of an immor💝tal, and thus became an artifact, or relic. That's not a beneficial outcome, Gollum.
