Oh, and for some perverse fun, when you have an instrument with courses of multiple strings (mandolin, 12-string guitar, lute, piano), try tuning one set of strings to even temperment & the doubled (or tripled) set using more perfect harmonic intervals. That way, you can annoy EVERYONE while still saying your instrument is "in tune". [grin]
