Chord Zither Competition

The term “chord zither” is a literal English translation of the German Akkordzither. Both are used in their respective languages as a general designation for zithers designed to permit the easy production of chords. Instruments doing this with a mechanical device or distinctive arrangement of the strings are often categorized thereby and named individually, typically as labeled in a patent.

The “autoharp” is a well-known example. It is also referred to as such in German-language discourse but was initially simply an Akkordzither. Such ambiguity led to the coinage of the generic term griffbrettslose zithern — literally “zithers without fingerboards” — of which the autoharp is one of many types. In German, a griffbrett can either be fretted, as on a guitar, or fretless as on a violin. In English, the former is a “fretboard.” After extensive discussion (detailed here) the generic heading in English settled on “fretless zithers” in analytical contexts.

Patent misrepresentation of patents

The history of fretless zithers is replete with inventions intended to ease the production of chords, first patented in one country and then claimed by someone else shortly thereafter, in a patent issued in another country. When the dates are close enough, it can be difficult to determine who should be credited with the actual innovation. Similarities do sometimes appear to be coincidental but plagiarism was common enough.

The assessment of such situations can be made more difficult by the widespread practice of marking an instrument with the date and number of the first patent issued for it, even if the model at hand incorporates details that do not figure in that patent. One frequently cited example is the way Charles F. Zimmermann applied the number and date of a well-known patent US257808 issued to him in the United States on 9 May 1882.

Guitar-zithers and barless autoharps

On 20 April 1893, Fredrick Menzenhauer, filed a US patent application for a “Guitar-Zither,” issued as US520651 on 29 May 1894. Its illustrations come very close to the form of fretless zither commonly termed a “chord zither.” The only differences are the tuning device in the middle of the soundboard underneath the first melody string, and the separation between the bass string and the other strings in each of the chords (which are also recessed into the lower bridge).
