78 Studies for Tuba were 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 to professional 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 for serious Tuba players who want to improve the quality of their sonority and their technique.
