Instrumental Duet Instrumental Duet,Tuba - Level 5 - Digital Download SKU: A0.934211 Composed by Mark Zanter. Contemporary. Score and parts. 6 pages. MJIC Music Publishing (ASCAP) #6040427. Published by MJIC Music Publishing (ASCAP) (A0.934211). Perpetuum Mobile (2014) for tuba, fixed media and processing was composed for George Palton, professor of tuba at Marshall University. I have worked closely with George engineering his solo CD, Tuba In Motion, and that influenced our collaboration on this work. George’s playing exhibits a full range of technical and expressive skills and the composition takes advantage of those strengths. The fixed media portion of the work was planned from the beginning; but as the work matured, processing was mixed with the live tuba enabling it to inhabit the same sound world as the recorded media. Overall the work is in three sections ending with a reprise of the opening material. Surface rhythms, textural changes, and the constant cycling of pitches occurring throughout the work exhibit the characteristic of moto perpetuo. A listener can perceive these myriad possibilities or simply enjoy the work’s virtuosity, lyrical melodies, changes of rhythm, and ambient sounds. Perpetuum Mobile was premiered on the International Tuba and Euphonium Conference 2014. I have to thank George Palton for the many great performances of the work.
