My electronic tuner has settings for several different temperaments.

I have several different harps each with a different number of strings and constructed in various ways from differing woods . They each "sing" or resonate to different keys and temperaments and so have different personalities. In other words, the various shapes and materials seem to cause the tones to coalesce or ring in different places. This doesn't mean they can't be played with other instruments, just that one needs to be aware when tuning. Most of the time it's a compromise, but I like to occasionally play them solo in their most comfortable key and temperament. You can really hear the difference.
