  Guidonian Hand Trombone Quartet - Biography  

Simple arithmetic applied to musical terminology demands that if you add up four trombonists, the sum should be called a trombone quartet. So why is it that I have trouble bringing myself to call Guidonian Hand a trombone quartet?…I don’t know, but I can say that Guidonian Hand is simply Guidonian Hand and nothing else because the sum of these four extraordinary musicians–Mark Broschinsky, William Lang, Sebastian Vera, and James Rogers–equals something beyond what the term ‘trombone quartet’ could muster in my imagination.


Everyone can hear this musical alchemy in their performances…As in any great performing ensemble, each member is in his own way the center of the group while at the same time no one is the center. That’s the magic of the sum of the parts. Each person brings something unique to the rehearsal besides his abilities on the trombone. Mark, a virtuoso on the alto as well as the tenor instrument, brings his genial humor and shrewd musical common sense–in this way he is the center; Will, skilled in every aspect of trombone playing and a musician of the most intuitive kind, brings his incisive musical insights–in this way he is the center. Sebastian, a gifted player with an especially lyric quality, brings a quiet steadiness and seriousness of purpose–in this way he is the center. James, whose sound as bass trombonist is as grand as his persona, brings his passion for music and his encyclopedic knowledge of the trombone–in this way he is the center. But then again, there is no center.


The Guidonian Hand Trombone Quartet

When the four personalities have merged, when what each player brings has been subsumed in the whole, there occurs that something which is always greater than the sum of its parts, the magic of great ensemble playing. That is what one hears at a Guidonian Hand performance.

–J. Mark Stambaugh, Composition Faculty Manhattan School of Music “




The Guidonian Hand transcends the limitations of the trombone by accepting them. Architecturally sound new music using everything of which the trombone is capable. Brilliant writing, brilliant playing. Loose and yet rigorously precise. Revelatory. A celebration of pure sound, and played from the heart at a very high level. Totally new. Go hear it.” –Sam Burtis, trombonist, bass trombonist, tubist, composer/arranger, music director, and educator in New York City since 1967

“More interesting, though, was [Conrad Winslow’s] “Dilating Music,” an atmospheric exploration of meaty lower brass textures, complete with subtle slides and juxtapositions of muted and open timbres, expertly played by the trombone quartet Guidonian Hand.” –The New York Times, Allan Kozinn, September 2, 2009
