Rob Perry has studied with Jeff Purtle since May 2012 and KO Skisness shot this video of Rob at the Stomvi booth at the 2013 International Trumpet Guild Conference. Rob is a comeback trumpet player and at the time of this video he had been playing less than two years. Also, he had never played a Triple High C before studying with me. Concepts like Tongue Level and K Tongue Modified unlocked many things in his playing, including the upper register. You can read his testimonial about this.
