There is no question that tuning by ear puts you in control of the
temperament but more importantly you come to experience the
"essence" or color in a way that cannot be done with any electronic
means.  However,  in my work I am called on to set a great variety
of temperaments, often under less than ideal conditions and time
constraints and find that carrying an electronic tuner is of great
assistance.  For ear tuning, two small pamphlets I would recommend
are the Jorgensen EQUAL BEATING TEMPERAMENT  and the Klop HARPSICHORD
TUNING.  Jorgensen is perhaps more accessible.  Both are available
from HCH in Boston.
