True, but there is no doubt that a bass tuba does not quite have the depth of tone down low, so would generally not be at its best for the part. Also there are more likely to be difficult fingering patterns if the part is faster moving. While the contrabass tuba requires greater care with pitching in its high register. However, range is only one factor for consideration.jonesbrass wrote:I've heard some simply say, "the range (tessitura) is high on piece X, so I'm playing on a bass tuba," or "that piece is written primarily below low Gbb, so I'm using a contrabass."
Another factor which I did not mention in my previous post is the nature of the part. Is the tuba playing a largely supporting (bass) role for the brass, or is it more soloistic. Going back to Mahler, symphony No.1, I would put as the former (excepting for the 3rd movement solo), while in No.6 the tuba is largely soloistic.
