The Organs of Mexico City Cathedral - Smithsonian Institution ...

Notes
' A range of 25 notes is incorrectly given here.
"De sostenido . . . re" means eft' to and including
d'", which is a range of 26 notes.
^ The Cadereta is the separate division, placed
at the organist's back (Rugwerk or Positiv).
There can also be a second windchest for the
Cadereta in the main case. In fact, the Cadereta
is divided into two sections. Both parts are playable
from the same keyboard. The smaller, freestanding
part is called in both dispositions "Positivo
de Espalda." The larger interior section is
called "Organo Cadereta."
^ The range of 24 notes is correct here. Instead
of 25 notes, as in the Epistle organ, C# is omitted.
making 24 in the Gospel organ.
"* In both dispositions, the pedal registers are
missing. The construction of both organs makes
it unlikely that the pedal registers are later additions.
It can be assumed that the omission of
these registers was an oversight.
^ 1 Vara is 84 cm.
^ In view of the sparse documentation, it seems
likely that the dispositions given in Musica y Musicos
may also have come from the Gazeta de
Mexico. The omission of the pedal registers could
point to copying from a possibly incomplete
newspaper article.
