Juan García Castillejo: Fast Telegraphy, the Trikeyboard and Electric Music (1944) [Spanish]

In this curious book, a Spanish priest proposes to combine the developments in telegraphy, teleprinter keyboards, typewriters and “electric music”. He describes how in the 1930s he built and perfected an ”electro-composition device”, equipped with lamps, transformers, capacitors, resistors, dozens of speakers and several engines.

He intended to cause the perforations in the telegraphic tape to be automatically selected by different engines that would trigger the various sound tracks recorded, and thus cause each of the “books on the perforated tape” to become an “audio book”. The purpose behind this idea was to enable the future creation of “spoken libraries” and “speech archives” in which the item being searched for could be instantly found. He performed practical experiments by means of a radio station where he managed to make the radio transmitter “speak automatically”, repeatedly broadcasting random announcements without anyone being present. He also intended this “talking device” to become an electric orchestra that composed “a music of chance configurations that was subjected to a number of panels governing its harmonic possibilities”, as well as bearing in mind the multiple possibilities that it offered in the field of improvisation.

Castillejo wrote several essays for a humour section of a radio magazine, which would imply that a concert was going to be broadcasted, when in fact it was the electro-composer instrument. In 1933, the director of Unión Radio, in Valencia paid him a visit him in order to evaluate how feasible its implementation in the radio station would be, although, due to the cost and difficulty in “providing a constant voltage for an electric demand that varied according to the use of a greater or lesser number of musical notes”, the project was shelved and fell into oblivion, and, with it, the contribution of the author. (from a summary by Miguel Molina Alarcón, 2006, pp 16-17)

Since 2008, Premio Cura Castillejo, a major Spanish award for sound art and experimental music is named in his honor.
