Tuning

Tuning a jews harp - lowering or raising the frequency of the lamella to a frequency corresponding to the closest note of a uniformly tempered twelve-pitch system at A = 440 Hz. Note that although it is technically possible to tune any jews harp to any note, the greater the deviation from the original frequency, the more the properties of the instrument change. Good jews harps optimally sound exactly in their own narrow range, and the bad ones simply do not need to be tuned;)
