Tuba & Euphonium: The Individual & The Ensemble

[David Richoux]

http://youtu.be/-RR-DUJv6cs An hour and a half long instructional video produced by the US Army Band. Topics Covered: History of the Tuba, History of the Euphonium, Posture, Hand Position, Breathing, Embouchure, Tone Production, Articulation, Individual Practice, Advanced Practice Techniques, Low Brass Sectionals

Not flashy, but informative. Generally accurate, although I heard a few questionable bits of info.
Don't think I have seen this posted here before, but could be wrong.
