A sympathetic musical instrument in the listening space is no big issue.
Fancy a symphony orchestra of ninety player and twenty are not playing.
Is the contribution of the seventy ruined by the twenty not playing.
Even more so, consider an orchestra of ninety with just one player making a solo. Is the contribution ruined by eighty-nine non-playing instruments variously sounding in sympathy!
Can a choir sing effectively in a church where an unplayed organ is also present?
Can a singer perform in the same room as an unplayed piano? Indeed can a piano be played in a room with 200 non-singing members of a chorus are present?
Obviously a musical instrument can live happily in a room where music sounds without ruining the music!
