Hi John, and the MMD readers.  Since "half" is a recent term and in-
appropriate (the Duo-Art being complete in all 3 forms: pedal, electric
and/or pedal-electric), I suggest continuing with the original terms,
of which there were two: "Foot-Impelled Duo-Art" and/or "Pedal Duo-
Art", both terms used by The Aeolian Company in the States.

The British terminology of "Pianola Piano - New Duo-Art type" is a bit
cumbersome, as well as several other variations which appeared in their
printed publications.

Actually, when all is said and done, "Duo-Art" or "Duo-Art Pianola" is
really enough, since it means a semi-automatic player which can employ
expression rolls, requires human monitoring in all forms (for tempo)
and which allows the operator to introduce his or her own musical
ideas, within the confines of the basic roll arrangement.  Whether it
has an electric motor or not doesn't affect the musical performance or
the aesthetics of the basic design.

'Half' for the manual instrument is only about 20 years old anyway,
and is in general use only within a certain portion of the collecting
clique right now.  When you think about it, the term is a subtle
put-down of that version of the versatile instrument, just as "repro-
ducers" and "pumpers" are for player terminology also within this same
circle.  Of course, nothing is as low as "snakebites" for the solo
system -- the Themodist -- which is the basis for the musical potential
that separates the Duo-Art from the divided-scale players like the
Ampico and Welte-Mignon.

Years ago I used to play Mah-Jongg extensively, and I ran into people
who used terms like "Soap," "Spinach" and "Daggers" for the White, Green
and Red Dragon tiles, among other trivializing words.  It affected me
similarly as these relatively-new and incorrect Pianola words of today.

Happy New Year!
