The autoharp takes wing

The preceding post traced the development of the colorfully named pig’s head psaltery from the 13th century through its mechanization near the end of the 19th century by the addition of damper bars. I promised to retell the same tale in a follow-up post — this one — focused entirely on its wing-shaped cousin. Beginning with a quick reminding look at a pig’s head psaltery, here is a typical representation in a sculpture on the 15th-century portal of the Saint Pierre Cathedral in Saintes, France.

This design appears to have been split down the middle in a comparable statuette on a late-14th-century gravesite monument in La Chaise-Dieu, France. The photo was taken at an angle from below and does not show the proportionality of the instrument’s sides as a frontal view would.

If the straight side at its top is envisioned as being longer than the side toward the player’s left arm, this becomes an archetypal wing-shaped psaltery. Multi-string courses and correctly positioned hands are clearly depicted, with a plectrum properly held in the right one (the left is too worn to tell). This suggests that the sculptor was paying attention to the instrument’s structure and use. It is also possible that it was an intermediate form on the conceptual path to the marked wing shape in the next image.

The preceding sculpted players are standing upright. A portrayal of King David in a mid-16th-century painting by Girolamo da Santa Croce shows him in a seated playing position. Psalteries large enough to need this type of support are variously seen flat on the player’s lap or an adjacent surface, or as here, with the back held upright against the player’s torso.

The structural details of the instrument in this image, and the extent to which it may be stylized, provide fuel for a good deal of interpretative discussion. I’ll leave that with passing mention for now, and simply use this painting as a springboard over a few centuries to a drawing of another wing-shaped instrument. This also includes mechanical detail serving a purpose that is not immediately apparent.

A pig-headed approach to the autoharp

The following image comes from a mid-15th century panel painting attributed to the workshop of Jan van Eyck. I’m aware of the pitfalls of assessing pictorial representations of musical instruments and might question a few details of the lute seen here. The psaltery and harp appear to be quite credible.

The bass strings of the psaltery are placed closest to the body of the player, who holds a quill in each hand. The right one is positioned to move across the entire stringbed, while the left one is centered on the bass strings. This asymmetrical design is termed a “wing shape.”

The Standard German word for wing is Flügel, which also designates a grand piano. A list of musical instruments in a German treatise from 1404 includes a flegil, together with a psalterium and two mechanized variants — the clavichordium (clavichord) and clavicymbolum (harpsichord). An illustrated description of an upright form of the latter appears in another treatise on musical instruments written ca. 1440. It fits a wing-shaped psaltery with a single quill for each string, increasing the number available for simultaneous use.

With the possible exception of the flegil, the instruments named in the preceding paragraph all belong to the generic category of “box zithers.” The present text will make its way toward a later facet of their mechanization, after considering what the difference between a flegil and a psalterium might have been. Since the harpsichord and clavichord are named with them on the same list, two plausible suppositions would be that the flegil was an early implementation of a hammer mechanism on a keyboard zither (something that has left other footprints), or an unmechanized relative of the psalterium that differed enough from it to merit a name of its own.

Zithers with chord bars and keyboards

The most widely encountered system for classifying musical instruments started out as an introductory essay to a catalog of the instrument collections of the Royal Conservatory in Brussels, prepared by their curator Victor-Charles Mahillon and published in 1888. His work was expanded by Erich von Hornbostel and Curt Sachs in 1914 and remains in widespread use as the “Hornbostel-Sachs Classification.” A specialist group publishes occasional revisions to it. Here is the segment of the current hierarchy where zithers appear.

3 CHORDOPHONES One or more strings are stretched between fixed points
31 Simple chordophones or zithers The instrument consists solely of a string bearer, or of a string bearer with a resonator which is not integral and can be detached without destroying the sound-producing apparatus
314 Board zithers The string bearer is a board; the ground too, is to be counted as such
314.1 True board zithers The plane of the strings is parallel with that of the string bearer
314.12 With resonator
314.122 With resonator box (box zither)
The resonator is made from slats NB This is true of the early piano only; modern pianos have no bottom and are board zithers. Harpsichords and some clavichords are box zithers Qin, koto, zither, Hackbrett, pianoforte

Numerous authors have extended this informally, following their own conceptual and terminological preferences. Qualifiers such as “chord” and “fretless” are frequently used in that context, branching further into individually named mechanized forms. The autoharp fits neatly into this framework but its physical attributes don’t always provide a sufficient basis for differentiating subtypes. Such things as alternate placements of damping pads on otherwise identical instruments may also need consideration. A hypothetical addendum to Hornbostel-Sachs might be headed “Box zithers with variable damping mechanisms” with specific types of autoharps placed below it.

The keyboard autoharp and gusli

Two recent posts discuss a manual technique for blocking chords on a zither with the fingers of one hand while plucking and strumming the strings with the other. This predates the use of mechanical chording devices on such instruments and can plausibly have inspired their development. I didn’t initially realize how vital that technique still is, or its geographic range, and have reworked both posts.

Rather than suggesting the reader look at them now, since the same technique figures in the present text, I’ll segue into its discussion with a demonstration on a gusli. This term designates a group of Slavic zithers of differing designs, commonly labeled by their shape.

Zithers gain leverage

Toward the end of the 19th century mechanical devices began to proliferate on zithers. Most of them were short lived, if marketed at all, but a few came into persistent use. One of their purposes was to enable a sequence of strings tuned diatonically in a given key to be shifted into others. Although this can obviously be effected simply by retuning the strings, for example, altering a G major scale to D major by raising all C strings to C♯, rapid changes require a more nimble auxiliary device.

Corresponding mechanisms were applied to chordal string arrangements, altering a block of strings from one type of chord to another. This was illustrated in the preceding post with a Swedish harp zither patented in 1886 by Adolf Larsson, equipped with a mechanism for shifting each supported major chord to the parallel minor or a seventh. This post’s banner image comes from a German patent (no. 266371) for an improvement on that device, issued to Larsson in 1913. A more recent two-position design is demonstrated here.
