Thomas Gregory asked about Ampico duet rolls [101014 MMDigest].
There are a few.

The Miessner "Melody Way" rolls and the "Tunes for Two" series are
all very elementary music, apparently intended for beginning pianists.
The "Melody Way" rolls contain simple music where the roll plays the
whole piece, then the roll plays only the left hand letting the live
pianist play the right, and vice versa -- they're not really duets.

The "Tunes for Two" are true duets in that the pianist plays the Primo
melody, generally just in octaves, while the roll plays the harmonic
Secundo part, but they are all very simple tunes like "America" or "Old
Folks at Home."  I don't know of any recuts of either of these series.

The Ampico rollography by Elaine Obenchain lists several "duet
recordings" but only two of those are true duet pieces written to be
played on one piano by more advanced pianists.  They are

  65651  Brahms  Hungarian Dance No. 5, Secondo, p.b. Sturkow-Ryder
  65663  German  Tarantella, Secondo, p.b. Sturkow-Ryder

I have not seen any recuts of these.

There are two pieces written for two pianos requiring some facility:

  68233  Mozart   Sonata for two pianos First Movement,
                  second piano part, p.b. Dumesnil
  68533  Arensky  Waltz from the Suite for Two Pianos,
                  first piano part, p.b. Cooper

Both of these rolls have been recut.  The Arensky Waltz can be played
on one piano since few notes are played simultaneously in the two
parts.  In the Mozart Sonata many notes are duplicated so it would be
somewhat awkward to play on one piano.

In addition, there are Ampico rolls of the solo parts to the first
movements of several concertos:

  68623  Grieg  Concerto First Movement, p.b. Volavy
  69243  Rubinstein  Concerto First Movement, p.b. Ornstein
  68843  Saint-Saens Concerto  First Movement, p.b. Levitzki
  80003  Mendelssohn  Concerto First Movement, p.b. Ornstein
    (not in Obenchain)

A pianist could play the reduction of the orchestral accompaniment
along with the solo part played by the Ampico.  I believe all of these
rolls have been recut.   I have not tried these, but I suspect there
are many note duplications so that the use of two pianos would be best.

Obenchain also lists:

  65371  Mozart Sonata K. 545 First Movement, p.b. Howard
  65383  Mozart Sonata K. 545 Second and Third Movements, p.b. Howard

This is a solo piano sonata, presented in full in these rolls.

Apparently Edvard Grieg wrote a second piano part to be played along
with the Mozart sonata.  I have not seen the Grieg so I don't know if
it could be played on the same piano as the roll.
