Tessellations 5 for Tracker Action Organ – 'The Sacred Geometry of Sound'. 

At last, thanks to the Novara Jazz Festival commission for an organ perfomance  there has been a chance for me to construct a piece for tracker action organ. Most of these organs are almost exclusively found in Christian churches worldwide. They are exceptional instruments in every sense. 

They are often intricately built to generate many colours using air blown through pipes of differing shapes, dimensions and materials. Tracker action organs are poetically very deep instruments and are completely non-binary. Perhaps more combinatorial (when applied to stop combining) with an organ stop on a tracker action organ; there is a mechanical connection that pulls a plate on a pipe via lines (trackers) and levers that then generates sound depending on that aperture, but already hugely dependant on the pitch, how many other notes are being played, how much wind is being generated, what increment the stop has been pulled (or pushed)The opening part of this piece attempts to illustrate this.

Unlike Tessellations 1, the recorded version of the piece only uses the first half the original 52 pentatonic scales as the main route which stop off at many sites and locations of sound as found in the research. More information on the Tessellations pieces, go to

Tessellations 5 for Tracker Action Organ

This is a composition by my friend - Frank Charlton who died during the pandemic. He wrote it for a quintet called Five Easy Pieces with Frank - trumpet, Veryan Weston - piano, Andy Gill - alto, Chris Rodel - double bass and Robbie Allen - drums. This was recorded sometime during the late 1990s. The drummer also died in the early 2010s. So this is a reminder of Robbie's and Frank's great music-making.

A piece Eternal Triangle recorded in December 2024 at my home studio.

Eternal Triangle are:

Trevor Watts - Alto saxophone
Jamie Harris - Percussion
Veryan Weston - Keyboard

I put some ideas around a lovely quicksilver 8-bar line Trevor plays that you can hear. His line has various harmonic implications which gave me a chance to use some discoveries of tetrachord pairs that are mirrors to each other. More information about Eternal Triangle can be found at:

Austrian born musician Iris Ederer is a versatile singer who is at home in various styles of music from jazz to contemporary composition and free improvisation. (http://soundcloud.com/iris-ederer). She has always been fascinated by the shapes and sounds available either, inside or outside of songs, irrespective of idiom.

She was born in Weiz, Austria. Early studies included learning to play flute, recorder and piano, before beginning to study jazz singing with Annette Giesriegl. After studying at the Carinthian State Conservatorium in Klagenfurt, she continued to study at the University of Music and Performing Arts Graz, mainly under the tutorship of established jazz singer and pianist, Dena DeRose. To develop her voice further, she studied classical singing with Mary Frances Lubahn, Milan Opera singer, Gerd Kenda and Gabriel Lipus.
Early work in singing and performing with choirs, including “Resurexit“, the alumni choir of the Ursulines Graz, which won prizes at the International Schubert Competition in Vienna, has led to running various choirs herself. This includes children’s choirs with ages ranging from 6 to 14 as well as adult choirs such as the Gospel Group Puch for almost 10 years, which culminated in recording their current CD “Sometimes I feel…”. She became Director of the KUG Jazz Choir at the University of Music and Performing Arts Graz for three years. She also curated the “Choir Fire” festival in Weiz for a number of years, a meeting platform for various choir styles from around the world.
During her first years of University she started to work with her former teacher Annette Giesriegl in a unique free jazz vocal ensemble and performed with it at many venues around Europe and as part of the VNM Festival Graz 2007. She also helped form The European Free Ensemble with Uli Rennert on piano, David Gromon on flute and Dan Hasalik on guitar. At that time she also started performing with vibraphonist and composer Berndt Luef and the pianist Michael Kahr. Her work with Giesriegl started to grow even more in Spring 2009. This was also when she met the British composer, pianist and improvisor Veryan Weston, who proved key in her future musical development. They together with Sofija Knesevic, Franz Schmuck, Dorothea Jaburek, Siruan Küng, Anush Apoyan und Patrik Thurner formed the international A Cappella group `VOCIFEROUS`. Together they performed Veryan Weston’s composition `Tessellations II for 9 Singers` which was specially written for the jazz festival `Singers and Voices` at the Orpheum Graz. There was a subsequent UK tour, part of which was recorded at the BBC Pinewood Studios that was later released in spring 2011 for Martin Davidson’s EMANEM Records.
Moving to London in 2012 was a very important step to develop her musical activities and her work with Veryan Weston further. Out of that, one of her current projects ‘Make’ with Veryan Weston (http://veryanweston.weebly.com/make.html) developed. Her relationship with London also furthered her connection to the Gathering with was founded by Maggie Nichols more than twenty years ago and with whom Iris has performed since. Iris also worked with leading experimental vocalist Phil Minton as part of his Feral Choir at the Extraordinary Voices Festival at the Barbican Centre in London and was part of Minton’s Feral Singers at a festival held at the British Museum inspired by the Ancient Egyptian Book of the Dead, which was filmed by Helen Petts.

Since she has moved to London, Iris has collaborated and performed at Festivals such as OV London, Art of the Moment Festival with music and dancing. Furthermore she performed John Eacott’s composition “Floodtide” – the sonification of the river Thames - at the Round House as part of the Accidental Festival 2013.

In November 2012 she started to work with Jane Alden’s “The Vocal Constructivists“. They were invited by the multi-talented Kasia Sobucka to participate in Deconstruction Project’s Jazz and Experimental Music From Poland 2012 Festival at The Forge, London. There they performed music of Bogusław Schaeffer, Jan Duszynski (b. 1976), Kasia Glowicka and Andrzej Koszewski (b. 1922). She will be part of a new recording taking part in November this year with the Vocal Constructivists recording compositions form composers such as Cardew, Applebaum, Redhead and Kuivilla.

The song based project, Tsk!, with baritone saxophonist David O’Connor (https://soundcloud.com/tsk-6) is a very new and fresh take on music and fusing a mix of styles. They and their sparse instrumentation bring together songs selected from a range of sources - jazz, folk, classical, metal, traditional, blues - as well as improvisational elements from jazz and free improvised music.

She also keeps her projects in Austria alive: a trio with Dusan Simovic on bass and Reinhard Summerer on trombone, singing with the R.S. Big Band who she has recently recorded with, performing with the Big Band Weiz as a soloist or with the latest vocal quartet she founded named "The Styrian Vocal Jazz Quartett" performing tunes in the style of Manhatten Transfer and The New York Voices.  One of her next perfomances will be a duo with pianist Marjolaine Charbin as part of the 2 day Festival “As Alike As Trees” in October 2013 at Café Oto. 
Also her first solo project “IRIS” will be released as a CD and book for the AV Akademikerverlag GmbH und Co. KG in the near future. It is a jazz-based recording featuring a rhythm section, trombone quartet and a flugelhorn, that latter an acknowledgement of the influence of the music of Kenny Wheeler’s upon Iris. The whole recording carries influences of experimental improvised music and English folk music with texts written by Iris Murdoch. In 2013 Iris’s performance of Veryan Weston’s “Make” won the PIARS competition recording award, which should lead to a recording being released on this label. http://www.fratto9.com/
