 Short octave - Wikipedia, the free encyclopedia
The short octave was a method of assigning notes to keys in early keyboard instruments (harpsichord, clavichord, organ), for the purpose of giving the instrument an extended range in the bass.
In one variant of the short octave system, the lowest note on the keyboard was nominally E, but the pitch to which it was tuned was actually C. Nominal F# was tuned to D, and nominal G# was tuned to E. Thus, in playing the keys:
Short octaves were also sometimes used in the organ.

 Frequently asked questions about Octave (with answers)
Octave has a real mechanism for handling functions that take an unspecified number of arguments, so it is no longer necessary to place an upper bound on the number of optional arguments that a function can accept.
Octave also has a real mechanism for handling functions that return an unspecified number of values, so it is no longer necessary to place an upper bound on the number of outputs that a function can produce.
Octave was not developed by the FSF, but the FSF does distribute Octave, and the developers of Octave support the efforts of the FSF by encouraging users of Octave to order Octave on CD-ROM directly from the FSF.

These short scale instruments can be suitable for beginners and for mandolin players looking for a second instrument, but if the octave mando is your main instrument you'll probably want the extra tone a longer scale length has to offer.
At first sight octave mandola is very similar to the ones sold under dozens of different brand names and is probably built at the same factory as the others.

is nonzero, Octave allows you to select elements of a two-dimensional matrix using a single index by treating the matrix as a single vector created from the columns of the matrix.
In Octave, unlike Fortran, function arguments are passed by value, which means that each argument in a function call is evaluated and assigned to a temporary location in memory before being passed to the function.
Although this is inconsistent with the normal behavior of Octave's lexer, which usually prefers to break the input into tokens by preferring the longest possible match at any given point, it is more useful in this case.

Pedals, no more than an octave in most cases, often merely pulled down lower keys of the manual, though they might have one independent 16' stop that was permanently on.
As you can see in the photograph to the right, they are made as short levers pivoted at their outermost point and placed at a rising angle as they extend toward the case.
In this particular instance, the fabric ties that connect the pedals to the lower keys of the manual are visible.

 Differences in Mandolin Family Instruments
This is another interesting factor- the bass strings are sometimes in octaves, going low to high from the bass side to the treble side (the opposite of a normal 12-string guitar tuning).
This is like a short scale octave mandolin with an added high [A], and similar to a short- scale tenor banjo in length and tuning.
Mandocellos are similar in tuning to the bottom four notes of a long scale cittern- the CGDA strings are in the same octave as the DGDA at the bass of the long-scale cittern.

The Brustwerk manual has the conventional bass “short octave” format that was customary in keyboard instruments throughout Europe before the 18th century.
The Great keyboard is similar, except the apparent F# and G# keys in the bottom octave are “split” to make those pitches available as well the D and E (an arrangement referred to as a “broken octave”).

 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).

The keyboard range was of forty-five keys (C1-C5), with a first short octave, while that of the pedal keyboard (always with a first short octave) was of fourteen pedals (C1-F2).
The bellows (probably three), equipped with a lever wind-raising device, supplied the nine-slide wind-chest, which was surmounted by a pipe-rack with a leather surface.

The two unison choirs are permanently engaged, and while there is no provision to change registration, one can move either of the traditional boxguide registers to disengage a choir, perhaps to facilitate tuning.
The keyboard of the original had a short octave bass.
Being of much wider octave span than later examples, we took the opportunity to modify it to our standard dimensions, this enabling us to extend the bass to fully chromatic from C.

 Notes on stops   (Site not responding. Last check: 2007-10-11)
It is most useful when played an octave higher providing an alternative 8 foot voice, and when used in this manner with the Diapason and Principal, a good 8' - 4' - 2' chorus is obtainable on the Great, but is of course, an octave short at the top.
The Octave is voiced very slightly brighter than the unison, although it can be used effectively with many of the stops, it really requires a firm 8 foot stop to be drawn first.
The use of this stop in combination with the Swell octave coupler gives the only 2 foot pitch on the organ (up to c3).This makes a huge difference to the ensemble, and therefore makes this a most valuable stop.

To me, "Octave Mandola" is wrong and defies logic, because it is not a mandola tuning, it is not an octave below the mandola tuning, and has nothing to do with a modern mandola.
The short scaled instruments tend to be the least expensive as well.
The tradeoff is that the short scale instruments are easier on your left hand, since you don't need to stretch as far.

What follows below is a short and very basic practical introduction to matlab/octave.
Octave is a free/openware (GNU) version of matlab: it is not completely identical with matlab and its graphing facilities are not as fancy, but it works well and is free (both price wise and following the free/openware philosophy).
The most basic thing you can do is to create a standard two dimensional plot: y as a function of x.

 History of the Harpsichord
The corresponding space at the bass end of the upper octave was filled in with a large key block.
The third and fifth keys, sounding as D and E, had to cross over keys F and G respectively to the left to be in alignment with the F, G, and A keys of the lower keyboard and their appropriate strings.
The dampers had to be cut very short so that the cloth wouldn’t be in contact with the strings when the jacks were in the off position.

 Paul Y. Irvin Harpsichords
Some compositions from this period can only be played on such keyboards, because the span of notes required to be played in the left hand is too wide to be comfortably achieved on a chromatic keyboard (several pieces of Louis Couperin come to mind).
This permits the strings to remain at the tension for which the instrument was designed, thereby preventing a major cause of broken strings and eliminating the usual two or three retunings needed to stabilize a new pitch level.
Instruments with short octave or broken octave tuning, as discussed above, do not take well to transposing keyboards since shifting the keyboards would necessitate retuning some of the bass notes by a rather wide margin which seriously shortens the life of those strings.

In addition, short duration sound pressure level measurements approximately 35-to-45 minutes in length, were performed at the beginning, and middle of the measurement periods at each of the three locations.

The 24-hour statistical sound level data at this location, as well as the Leq data of the short duration measurements, were used to estimate the DNL sound level at this location.

Keyboard instruments varied in compass according to the period, the normal range at the start of the 17th century being approximately four octaves (from the second C below middle C to the second C or D above middle C).
This compass was extended further into both the low and high registers to reach a total of 5 octaves by the middle of the 18th century.
A 4-foot stop therefore sounds one octave higher than written and a 16-foot stop one octave lower.
