    Tuning forks as resonators --- When 2 identical tuning forks (the same Hz) and sounding boxes are placed next to one another. Striking one tuning fork will cause the other to resonate at the same frequency, just like a vibrating string. When a weight is attached to one tuning fork, they are no longer identical. Thus, one will not cause the other to resonate. When two different tuning forks are struck at the same time, the interference of their pitches produces beats.

    April 9, 1988 in Milan, Italy, the Schiller Institute brought together some of the world's most highly-regarded classical singers and instrumentalists, to demand a return to rationality in musical tuning and performance. The demand was led by the top speakers at the conference, renowned operatic soprano Renata Tebaldi, baritone Piero Cappuccilli, and Helga Zepp-LaRouche. They and others called for an end to the high-pitched tuning, which has been literally destroying all but the most gifted voices during the past century, and for a return to the principles of classical aesthetics, according to which the process of musical composition is just as lawful as are the orbits of the planets in the solar system. To underline this call, the conference resolved to introduce legislation into the Italian parliament which would require a return to the natural tuning at which middle-C equals precisely 256 cycles per second--significantly lower than the current tuning which sets A at 440 cps--or frequently even higher. The fact that this is no mere professional detail, was underlined by the star-studded list of endorsers of the conference's aims. That list includes: Spanish soprano Montserrat Caballe, Swiss soprano Anneliese Rothenberger, Spanish tenor Alfredo Kraus, Austrian violinist Wolfgang Schneiderhan (former close associate of Wilhelm Furtwangler), German bass Kurt Moll, Mexican-Spanish tenor Placido Domingo, German soprano Edda Moser, and Italian tenors Luciano Pavarotti, Carlo Bergonzi, and Giuseppe Di Stefano. The conference took place at the Casa Giuseppe Verdi, the Renaissance-style building which the great Italian composer had built for retired musicians, with French 'cellist Eliane Magnan and pianist Marie-Pierre Soma playing the "Allegro ma non troppo" of Beethoven's Sonata No. 3 in A Major.

  • The Classical Revolution- A Prelude

    The three part compilation is a preview of sorts which touches on the themes of an upcoming DVD, now in progress titled, "The Classical Revolution." Those three sections are here outlined in brief:


    The Congress For Cultural Freedom --The counter-culture which was promoted as an intelligence operation by powerful financial interests, has now become the culture.


    What does one do when the state is corrupt, and the masses are apathetic? Where does change then actually come from? Friedrich Schiller found a really fantastic response: that it can only happen through classical art.


    At the time of Verdi, the pitch was 432 Hz (C=256) and he wrote his operas for that pitch.  Going back to the Verdi tuning, and thereby breaking the perverse trend of the last decades of tuning ever higher, is a matter of respect for the artistic will of the composer, for his idea of color, of sound, of color of the voice, and also respect for the vocal instrument.

    French 'cellist Eliane Magnan and pianist Marie-Pierre Soma play the "Allegro ma non troppo" of Beethoven's Sonata No. 3 in A Major April 9, 1988 at the Casa Giuseppe Verdi, the Renaissance-style building which the Italian composer had built for retired musicians. This piece opened a conference held by the Schiller Institute on the subject of lowering the musical pitch to a scientific tuning that reflected an 1884 Italian War Ministry decree with which Giuseppe Verdi and a group of musicians and scientists established as C=256 (A=432) as the "official scientific tuning-fork" in Italy.
