'Trombone Walking' was originally written as part of a larger site-specific collaboration with dance called 'Imprint.' The intention is for the trombonist to walk while playing the composition. Either the trombonist can memorize the composition or play with a lyre. One option in concert performance is to begin the work behind the audience or offstage and then proceed to the stage or around the audience. Regarding the playing and singing, it is understood that different players will have different vocal ranges. The primary version marked is the original version as was performed by Jeremy Berkman. The ossia versions where marked accommodate a male trombonist who may not be able to sing as high as the first version. For female trombonists, please sing in whatever octave works best. In general, any other changes to these parts should be done so that the sung note is above the played pitch.
