from La Nature, 1883

A cat organ or cat piano (Katzenklavier in German) is a conjectural musical instrument which consists of a line of cats fixed in place with their tails stretched out underneath a keyboard so that they cry out in pain when a key is pressed. The cats would be arranged according to the natural tone of their voices.


from J-B. Wecherlin, Musiciana

There is no official record of a cat organ actually being built; rather it is described in literature as a bizarre concept.

This instrument was described by the French writer Jean-Baptiste Weckerlin in his book Musiciana, extraits d’ouvrages rare ou bizarre (Musiciana, descriptions of rare or bizarre inventions):[1]

When the King of Spain Felipe II was in Brussels in 1549 visiting his father the Emperor Charles V, each saw the other rejoicing at the sight of a completely singular procession. At the head marched an enormous bull whose horns were burning, between which there was also a small devil. Behind the bull a young boy sewn into a bear skin rode on a horse whose ears and tail were cut off. Then came the archangel Saint Michael in bright clothing, and carrying a balance in his hand.

The most curious was on a chariot that carried the most singular music that can be imagined. It held a bear that played the organ; instead of pipes, there were sixteen cat heads each with its body confined; the tails were sticking out and were held to be played as the strings on a piano, if a key was pressed on the keyboard, the corresponding tail would be pulled hard, and it would produce each time a lamentable meow. The historian Juan Christoval Calvete, noted the cats were arranged properly to produce a succession of notes from the octave... (chromatically, I think).

This abominable orchestra arranged itself inside a theatre where monkeys, wolves, deer and other animals danced to the sounds of this infernal music.[2]

The instrument was described by German physician Johann Christian Reil (1759–1813) for the purpose of treating patients who had lost the ability to focus their attention. Reil believed that if they were forced to see and listen to this instrument, it would inevitably capture their attention and they would be cured (Richards, 1998).

The instrument was first described by Athanasius Kircher in his work Musurgia Universalis, though the lack of an image may have left doubt in the minds of some writers. (The New York Times, for example, has carried an article claiming he described the instrument,[3] and another stating he did not describe it in Musurgia Universalis.[4]). His description appears in Book 6, Part 4, Chapter 1, under the heading "Corollaria," (emphasis added):

Constructum non ita pridem ad melancholiam magni cuiusdam Pincipis depellendam abinsigni ingeniosoque Histrione tale quodpiam instrumentum. Feles vivas accepit omnes differentis magnitudinis,

quas cistae cuidam huic negotio dedita opera fabricatae ita inclusit ut caudae perforamina extentae, certis quibusdam cana, libus insererentur affixae, hisce subdidit palmulas subtilissimis ac uleis loco malleolorum instructas; Feles vero iuxta differentem magnitudinem tonatim ita disposuit; ut singulae palmulae singulis responderent felium caudis, instrumentumque ad relaxationem Principis praeparatum oportuno loco condidit, quod deinde pulsatum eam harmoniam redditit, qualem Felium voces reddere possunt. Nam palmulae digitis Organoe di depressae aculeis suis dum caudas pungunt cattorum hi in rabiem acti miserabili voce, nunc gravem, modò acutam intonantes, eam ex felium vocibus compositam reddiderunt harmoniam, quae et moveret homines ad risum, et vel sorices ipsos ad saltum concitare posset.[5]

from Gaspar Schott, Magia Naturalis

The citation is noted by Kircher's student Gaspar Schott in Magia Naturalis naturae et artis, Part 2, Book 6, Pragmatia 2, titled "Felium Musicam exhibere."[6]

Modern citations and reconstructions[edit]

Kircher notes that the instrument can be used to reduce the melancholy of princes by moving them to laughter, almost exactly the situation that occurred in 2010 when Prince Charles was greatly amused by a performance of the tune "Over the Rainbow" on an instrument recreated using squeaky toy cats by Henry Dagg for a garden party held at Clarence House supporting Charles's Start initiative for sustainable living.[7][8]

In 2009, The People's Republic of Animation, a professional animation studio, released an animation titled The Cat Piano. This work tells the tale of a city of cats whose musicians are kidnapped by a human in order to make a cat piano. This short film has received several awards, as well as nominations for awards. The Academy announced that it was shortlisted for an Oscar for Best Animated Short. However, it was not nominated.
