Tubing Connections for Seeburg Style "L"
And Other A-roll Cabinet Pianos
The small Seeburg L cabinet piano has 54 notes The lowest bass note
is the third B below middle C, equal to note 15 in an 88-note piano.
The highest treble note is the third E above middle C, equal to note
68 in an 88-note piano. The pitch standard is A=435 Hz.
With eleven wrapped two-string bass unisons playing from low B up
to A, the lowest plain string on the long bridge is the second A# below
middle C (note 26 in an 88-note piano).
The Seeburg L plays 65-hole style "A" rolls These rolls play 58 notes,
from C through A (notes 16 through 73 in an 88-note piano). Although
the lowest note in an "A" roll is C and the lowest note in a Seeburg L
is B, the L does not transpose, but is tubed to play at concert pitch.

The same piano and scale are used in the late style keyboardless
Seeburg model C with xylophone, the Western Electric Mascot, and the
Coinola Cupid. Western Electrics and Coinolas do not have a pneumatic
expression device for tracker bar hole #1, and use only the hammer rail
for automatic expression.
Larger keyboardless A-roll pianos, including the Seeburg K and Western
Electric X, were copied from the Automatic Musical Co. keyboardless
piano made by Haddorff and later used in the Link 2-E cabinet piano.
This piano has 61 notes tuned from G-G In A-roll pianos, the lowest
three notes are not used, leaving a 58-note scale of low A# through
high G and transposing "A" rolls down two half steps Consequently they
sound a little "tubby" compared to their keyboard-style counterparts.
(The same piano back was also used in G-roll and 4X-roll pianos
including the Seeburg KT, KT Special, equivalent Western Electric
models, and the Nelson Wiggen 4X, 5X, and 6 With three unused bass
notes and 10 octave-coupled bass notes, they play in the correct key,
unlike their A-roll counterparts.)
A few Nelson-Wiggen Style 8 keyboardless pianos that play "A" rolls
have little 54-note pianos as in the Seeburg L et al, but most of them
have full 58-note pianos They are non-transposing, making them many
collectors' favorite little A-roll pianos because they are the only
ones that play the music as intended They are also the only little
American nickelodeons that were originally tuned to A-440.
