| | SAPAAN: Historic Organs of Oaxaca - Notes |
 | | The advantage of a short octave system is that it sacrifices little-used notes for economy of size (keyboard and instrument case width) and materials (added strings, pipes). |
 | | The most usual form is the C short octave, where the lowest key (apparent E) plays low C. The natural keys F, G, A and B all play their proper pitches, but the F-sharp and G-sharp keys plays low D and E respectively, leaving the notes C-sharp, E-flat, F-sharp and G-sharp unrepresented in this octave. |
 | | The keys are very short, pivoted just behind the nameboard, so the pins cannot open the pallets directly; their downward motion must be transfered toward the rear of the case through a system of intervening backfalls (levers). |
