I have an old Besson tuba (1955 vintage) that was sold to me as a BB-flat but I have now discovered that it must be an E-flat. Using the fingering chart on this web site, it tracks well in the middle and upper range but since the chart is for a 4 valve, below low B-flat it falls apart. Does anyone have the fingerings below low B-flat for a 3 valve E-flat tuba??
