Jeff Whittier's D'tzus were chosen over many other bamboo flutes, including those imported from China, by the composer of "Miss Saigon" for use in his musical. In a blind audition held by the flautist for the musical, Lisha McDuff, Claude-Michel Schonberg chose these flutes for their purity of tone and superior intonation.
