These 27 vocalises are masterfully compiled, transcribed, and edited by trombonist Alan Raph and include etudes from Giuseppe Concone, Gaetano Nava, Giovanni Lamperti, and Mr. Raph himself. They can be used as etudes in the practice room to focus on legato phrasing, dynamics, and bass trombone register, or can be performed with piano as works highlighting phrasing and interpretation. Piano accompaniment is available as a digital download from the publisher's website.
