Ernst Krenek’s Buchla Synthesizer (Part 2)

As we saw in part one of our report, there is a significant amount of sound potential in Ernst Krenek’s Buchla System – all the more since it consists of two instruments. In reality, it’s twice as big as it looks. Although the Buchla 100 Series is optically no match for the Moog Modular System or the ARP 2500, it was not exactly cheap when he purchased it in 1967.

If Ernst Krenek hadn’t laid the foundation for his modest wealth many decades earlier with the opera “Jonny spielt auf”, he wouldn’t have been able to afford the Buchla. [The opera opened 1927 in Leipzig and played a total of 421 nights during its first run.]

From the beginning of the 1940s, Krenek had been involved in Serial Music, along with Aleatoric and Electronic Music. And an invitation to the Studio For Electronic Music of the WDR in Cologne in the 1950s had initially encouraged him to establish his own electronic music studio.


“He became an American citizen in 1945. He later moved to Toronto, Canada, where he taught at The Royal Conservatory of Music during the 1950s. His students included Milton Barnes, Lorne Betts, Samuel Dolin, Robert Erickson, Halim El-Dabh, Richard Maxfield, Will Ogdon, and George Perle. He died in Palm Springs, California, where he had lived since 1966. In 1998 Gladys Nordenstrom founded the Ernst Krenek Institute; in 2004 the private foundation moved from Vienna to Krems, Austria.”



We’ll close our brief resumee of Ernst Krenek and his Buchla Synthesizer with further pictures of his instrument (and of the Buchla filter 291).

“Es genügt, einen Ton schön zu spielen” sagte der Komponist Arvo Pärt im Jahre 2005. Diese Aussage ist ebenso einfach wie ich auch exzellent: Es braucht kein Meer an Tönen, denn entscheidend ist der Klang. Dass so mancher Vintage-Synthesizer der 70er und 80er Jahre teils unerreicht hochwertige Klänge liefert, steht außer Frage. Doch tatsächlich leben wir “heute” in einer nahezu perfekten Zeit. Einerseits hat man – mehr oder weniger – noch Zugriff auf die Vintage Analogen, andererseits wird auch bei Neugeräten die wichtige Komponente des hochwertigen Klanges wieder zunehmend berücksichtigt. Doepfer, Cwejman,, MacBeth, Moog, GRP, Studio Electronics, COTK, John Bowen und andere Hersteller bauen hervorragende Synthesizer, die den “Klassikern” in nichts nachstehen. All diesen (alten wie neuen) “großartigen” Instrumenten ist Great Synthesizers gewidmet. _________________________________________________________ In 2005 composer Arvo Pärt said: “Playing one tone really well is enough”. In other words, it is sufficient to play one tone 'beautifully'. I agree with that. All musical efforts are focused on the sound itself. Although I studied classical music (piano and drums), it’s the electronic sound that inspires me. Synthesizers are the epitome of new sounds and exciting tonal spheres. Today, many companies produce high-quality - excellent! - synthesizers: Doepfer, Cwejman, MacBeth, Moog, GRP,, COTK, Studio Electronics, John Bowen and others. It's their products I'm really interested in ... apart from Vintage Synthesizers, which I have been collecting for 20 years. Subsequent to our former websites Bluesynths and Blogasys, Peter Mahr and I have now created GreatSynthesizers. We hope you like it.
