||"Preparatory Scales And Arpeggios For Tuba" was written by Micky Wrobleski. As the Principal Tubist for the Beijing Symphony and Professor of Tuba at the China Conservatory of Music , Mr. Wrobleski is eminently qualified as both a performer and teacher. This 17 page book is designed to help the student to improve technique and breathing. Next step is the more advanced "Scale Drills for the Tuba" book which is also published by RGM. Also available as a PDF.
