9 Beet Stretch is Ludwig van Beethoven's 9th symphony stretched to 24 hours, with no pitch distortions. 9 Beet Stretch was made at Notam, Oslo, and is indebted to Anders Vinjar, Kjetil Matheussen and Bjarne Kvinnsland at Notam, who made this work possible, and to Bill Schottstaedt who made both the Snd or the Common Lisp Music software which made this execution work so incredibly well, Jeff Hunt at Table of the Elements for making the first concerts possible (and many more later). My sincere gratitude also to Harold Schellinx and Park4DTV who ran the stream and app of 9 Beet Stretch for almost 10 years, and to Fabian who also ran the stream for years.

The source recording for this version on stream is a Naxos recording conducted by Béla Drahos with the Nicolaus Esterházy Sinfonia and Chorus (Naxos 8.553478). Sincere thanks to Naxos USA!

Thanks also to all the enthusiasm shown to 9 Beet Stretch. That has really brought the work around and made 9 Beet Stretch into the event it is.

9 Beet Stretch has been presented as installation, ½ concerts, or otherwise segmented concerts at various venues, like at Center for the Arts, Wesleyan University, Middletown; Alte Oper, Frankfurt; Echoraum, Wien; Ny Carlsberg Glyptoteket, København; [ars]numerica, Montbéliard; Jetlag No. 4, Pact Zollverein, Essen; Norwegian Sculpture Biennal 2006, Vigelandsmuseet, Oslo; Brakstad Konsept, Oslo.

9 Beet Stretch Last 40" is an excerpt I often present, and this is as title say, the last 40 minutes of 9 Beet Stretch. I have at an occasion also titled this The Final Finale

Every concert of 9 Beet Stretch is very much a coopartion with venue and curator. 9 Beet Stretch has been installed in a wide range of spaces, from bedroom to huge industrial halls like the Kupfer Ironworks, and churches as the 11th century Bergen Cathedral. An earlier installation at Brakstad Konsept took place in the gallery's bedroom (thus the title then; «Bedchambermusic»), and 9 Beet Stretch had its perfect marriage between work and venue at 964 Natoma – which was known for its listening space filled with madrasses and beansacks. In any space, good contemplation furniture makes a difference, and a venue would be greatly benefited by having a split between a dedicated listening space and a lounge of sorts where people can talk and socialize.

During the covid-19 pandemic Mauricio Reyes initiated and curated 9 Beet Stretch 2.0: Meta Tones, a release where 12 artists where given a 2 hours segment each of 9 Beet Stretch to work on. The 12 contributing artists were CM von Hausswolff, Mykel Boyd, Jac Beloeil, Frans de Waard, Oleg Puzan, Michael Esposito, Marc Behrens, Adi Newton, Manuel Rocha Iturbide, John Duncan, Mauricio Reyes and Leif Inge. The full 24 hour 9 Beet Stretch 2.0 was released in 2021 on 32GB UDP / USB Chip by Telekinett (Tele 008) and also in boxed sets including the original 9 Beet Stretch in full : - )

Alexander Rehding's book about Beethovens's Symphony No. 9 is an incredible thoroughly dive into Beethovens 9th and in all its historical and musical aspects, and I am truly honored that 9 Beet Stretch plays an important role in this book. 2018.

A Field Guide To Table Of The Elements (CD), a release from the people who have been the strongest supporters for 9 Beet Stretch ever, the record label Table of the Elements. This CD includes the 9 Beet Stretch Last 40" which is, well, the last 40 minutes of 9 Beet Stretch, as well as Aaron Ximm's Idea of Ninth. 2006.

RadioLab aired Aaron Ximm's intensely beautiful Idea of Ninth, a collage of reactions from audience at the concert of 9 Beet Stretch at 964 Natoma, San Francisco in 2004. Listen to RadioLab's episode on Time. 2004.

9 Beet Stretch

A recording of Ludwig van Beethoven’s 9th symphony is to be stretched to 1 day – 24 hours – with no pitch distortion.

For concerts or installation, use either supplied material or augment any full length digital recording of Beethoven’s 9th symphony. As the length of the source recordings varies, so will the ratio of the augmentation vary to reach the full 24 hours length. With a partial performance, the performed part must be augmented with the same ratio as would the whole recording.

There is a version for 9 Beet Stretch for each recording available of Beethovens 9th symphony.

If there for any reason is hard to obtain a copy of Beethoven’s 9th symphony, please use Wolfgang Amadeus Mozart’s Requiem.

Some Techs and General Information

The early files was made with Snd (pronounce it «sound») in 2002. In 2004 a remake was done using Common Lisp Music, then preparing for the starting and still ongoing concert series. Both Snd and CLM is made by Bill Schottstaedt.

Granulation divides the sound into short enveloped grains and reproduces them in high densities ranging from several hundred to several thousand grains per second. Slicing the input file into short pieces, then overlapping these slices to lengthen (or shorten) the result allows a change in the speed at which things happen in a recorded sound without changing the pitches.

The ratio of augmentation reach 24 hour will vary depending on which source recording used. The sources I have seen range from 64' to 78', giving a ratio somewhere in the range of 19 - 23 times.
