78 Studies for Tuba was composed by Boris Grigoriev (1906-1978), a Russian trombonist who trained many professional tuba players. Requiring some mature technical knowledge, these etudes would benefit to advanced students toprofessional players. Quite lyrical and with a strong Russian influence, these studies have a low register work and cover all keys, moving progressively to sharps and flats. Really enjoyed by tubists, these are a must-have forserious tuba players who want to improve the quality of their sonority and their technique.
