I need advice on leaving my two harps (Lyon and Healy 85 and a Salvi lever harp) locked up in a room for 1 year long depending on how quickly Covid blows over. The harps are both tuned up and won’t be played for this duration.
Should I de-tune the harps by a few semitones and keep its cover on or what is best advice? I heard its damaging to de-tune them completely, and also on the other side, if a string breaks on full tension when no-one can replace it?
Thanks in advance
