All works recorded

Posted on April 29, 2015 by Matt Barbier

Recently the two central works for face|resection, by Clint McCallum and Nicholas Deyoe, were recorded down at UCSD by Scott Worthington. The two works are also editing and we’re in the process of mxing. The music should be ready for pressing in the next few weeks!

face|resection’s online presence

Posted on February 14, 2015 by Matt Barbier


A critical part of the face|resection grant application is that, in addition to printed form, all the etudes and recordings will be available for free online. Growing from this and from our mutual interest, the online home for this information will be part of a blog created in collaboration with fellow trombonist, Weston Olencki.

This blog will be the home for the hosting and distribution of the face|resection materials and etudes as well as other writings and recordings by myself and Weston devoted to the sonic and technical expansion of the trombone. This collaboration will be a place for me to expand upon the etudes and ideas of the face|resection project to create a stronger final result.


Additional updates will follow once the blog is launched and my articles and etudes for the face|resection project are published there. The first of my face|resection articles will be published in early March. 



Our blog’s mission statement:


The Rage Thormbones blog is a collaboration between trombonists Weston Olencki and Matt Barbier devoted to the furthest reaches of trombonistic exploration/experimentation, and its subsequent dissemination. Featuring individual and collaborative writings, the blog will break down techniques found by our individual explorations, discoveries, and the expansion of preexisting pedagogical ideas in relation to the production of various non traditional playing techniques . Additionally, Rage Thormbones will host writings about mental/physical/conceptual approaches to performing individual and disparate repertoire.


By breaking down [chosen] techniques into the simplest processes of pedagogy, Weston and Matt hope to shed further practical light on them and thus allow a further understanding and performance life of the repertoire that utilizes the outer reaches of brass technique.

As the blog develops, it is a subsequent goal to host responses and conversations with composers whose work is explored, as well as other trombonists and brass musicians investigating similar aesthetics, ideas, and repertoire – thus further opening up lines of communication into these otherwise very private and internal thought processes.


Face Resection is the culmination of several years exploring the extremes of physical endurance and noise creation on the trombone. Through extensive work with Nicholas Deyoe and Clint McCallum we have created two works which greatly expand the previous use of established, but uncommon, extended techniques. I am seeking funding to help record and release these two works alongside a series of etudes and explanations detailing these developments. My desire is to create a sound recording and small publication that will be of use to both performers and composers to help share this music and expand this underutilized performance technique. Both the sound recording and publication will be released in physical and digital formats.

Lip-multiphonics (or split-tones) are a wonderful, but under-utilized and rarely learned technique. They are made by buzzing the lips between two adjacent harmonics and activating both harmonic nodes simultaneously, creating a singular sound. Given the difficulty in controlling them, lip-multiphonics have been used sparingly and in a limited role and generally only by the most extreme of specialists.

My goal is to expand the versatility and accessibility of this technique into more comprehensive registers of the instrument, as well as to augment it through uses of circular breathing, articulation, adding the voice, and other methods of manipulation. With added flexibility, these techniques can be used in a more musically integrated way than as a mere sound effect.  A huge application of this work is with the solo pieces of Nicholas Deyoe and Clint McCallum, which extensively push the previous written limits of lip-multiphonics.

Nicholas Deyoe’s facesplitter pushes lip-multiphonics into new limits of range and integration into form. He uses them not as a sonic augmentation, but as integral structural element. Facesplitter demands that lip-multiphonics be as accessible and facile as any other sound on the instrument while pushing them into previously impossible registers. In Bowel Resection, by Clint McCallum, lip-multiphonics are pushed in a completely different and equally uncharted direction. Rather than finding new multiphonics, Clint took a radical approach by pushing the simplest one to its limit. His piece is simply one multiphonic which must be sustained, through circular breathing, and rapidly articulated for the duration of the work. Neither of these techniques, or many in facesplitter, have been previously used in the trombone repertoire.

Throughout the development of these techniques, I have kept careful notes of how they were learned and made etudes for myself. An important aspect of this project is to publish a series of etudes aimed at showing trombonists how to learn and control these sounds. By illustrating their use through etudes and repertoire, my hope is that this will also prove to be an effective reference for composers interested in lip-multiphonics. It will illustrate their versatility and range, while also giving a clear understanding of the demands required to learn them. My hope is that this will expand their affective use among players and composers.
