"Cope has been very precise in his notation
throughout the work, an advanced composition...an exciting avenue
for the tuba player looking for one of the newer directions to pursue."
--Robert Levy, Brass World, vol.8, no.1
"David Cope, in his composition Spirals
for tuba and tape, is perhaps the most adventuresome in his use of
new techniques. The overall effects....do not interrupt the general
flow of the music. Cope has achieved in this piece an experience for
both audience and tubist."
--Barton Cummings, The Contemporary Tuba, 1984 (Whaling
Music Publishers, New London, CT.)
