The spike organ or nail chello (sic) is thought to originate from an early middle Europe monastic sect, the Iscariotians. They may have used the instrument to accompany their lengthy rituals contemplating the pain of the crucifixion.  

The Iscariotians are said to have been wiped out by returning crusaders at the behest of emperor Leopold III. Other commentators have suggested that the whole story may have been a constructed  alibi for the defeated crusaders plunder and desecration of the brewery of ..Santa Quaffa...


A possible surviving 'chello' object, made from of lignum vitae and iron, resides in the Musée des Beaux-Arts de Rouen. Its interpretation is not without controversy with some critics asserting the object is nothing more than a kind of agricultural implement, though this does not explain its cruciform shape and carved decoration.

In 1972 the scholar . Roland de Févin was granted permission to investigate the Rouen Chello, explore its sound making capabilities and make recordings. his theory was that the instrument was to be played by a rosined bow.  Unfortunately de Févin's playing and handling resulted in two of the nails fracturing and so the investigation was terminated after only one day. The single recording de Févin made was never released but it was played to audiences on an European lecture tour he conducted shortly before his death in 1974. 

It has been subsequently alleged that de Févin's  investigation  coincided with the great fire at  Nantes cathedral. This lead to several occultist conspiracy theories, most notably retold in the pulp fiction novel Blood Nail-(Brownie Dane,1975) much of the plot was lifted for the Italian soft core film Sistero Orgasma (1977) where the action was switched away from a monastery to a scantily clad convent.(citation needed) 

On the film soundtrack, the sounds of the Chello were replicated by experimental electronic synthesiser the achoirorium- itself the  subject of intrigue- as its extremely high operating voltages caused the death of its creator  Luigi soon after the recording session.


This recording was made in 1980 by UK avant geographer Forster Iberix who attended several of de Févin's lectures.  He set about building a replica device and making reconstructions of the Iscariotarian mass based on a column of scribbled numbers  which appear reverso  in one of Leonardo da Vinci's codex's (Coded notebooks). The recording was released on an untitled flexi disk issued by cult French label sordide sentimental -who now deny any knowledge of its existence. It does not appear on their official discography.  Improbably- Haringey local studies library, London, has a copy in their archive. The library does not provide any method of playback for the flexidisc and items from the archive cannot be withdrawn -so some subterfuge was involved in me getting this track taped. Whilst the disk was in my possession an inexplicable number of minor disasters befell me -so I can assure you I hurriedly returned it.

I've recently discovered (at long last) the music of Danish composer Per Nørgård. He developed a compositional techniques based on what he called the "infinity series", which is a simple formula for developing a series of numbers based on an interval such as a minor second. The series takes the initial interval and then slowly expands upon it both upwards and downwards in pitch, getting broader in scope as it progresses. This idea can be used to generate melodies, rhythms, or other aspect of a composition.

I decided to try playing around with this, but applying it to microtonal intervals, using Csound and a Python script to generate the Csound score according to the series. I ended up with this brief study, which takes the first 256 terms of the series and applies it to three of my favorite intervals simultaneously:
 - 9/8 (major whole tone from the 9th harmonic)
 - 11/8 (unidecimal tritone,from the 11th harmonic)
 - 7/4 (septimal minor seventh, from the 7th harmonic)

The starting tone (240 Hz) plays throughout the piece as the other notes unfold above and below it. I used sine waves processed with a touch of tanh distortion to add a slight amount of harmonic content.
