Building The Embouchure - Book 2 (Neuheit Tuba) Building The Embouchure - Book 2 continues the work begun in the first book by focusing exclusively on minor keys. This new collection of legato studies for tuba is designed to further develop embouchure strength, breath control and tonal quality while fostering the musical sensitivity associated with minor tonalities. The exercises emphasize smooth note connections, stable intonation and an even sound throughout the instruments range. Through a carefully structured progression, players can improve their control, endurance and phrasing while reinforcing essential technical fundamentals. A natural continuation of the first book, Building The Embouchure - Book 2 provides an excellent daily practice resource for tubists seeking to build a strong, flexible and expressive embouchure through the art of legato playing in all minor keys.
