▁new ▁full ▁score ▁based ▁on ▁the ▁original ▁published ▁parts ▁was ▁produced ▁by ▁Bo ose y ▁& ▁Haw kes . ▁Multiple ▁errors ▁are ▁found ▁in ▁the ▁score ▁that ▁are ▁not ▁shown ▁in ▁the ▁original ▁parts . ▁ ▁This ▁new ▁edition ▁contained ▁several ▁modifications : ▁ ▁The ▁fl ute ▁and ▁pic colo , ▁originally ▁key ed ▁in ▁D , ▁were ▁changed ▁to ▁the ▁key ▁of ▁C , ▁as ▁this ▁was ▁becoming ▁increasing ly ▁popular . ▁ ▁The ▁B ▁bar it one ▁part ▁was ▁disc arded . ▁In ▁ 1 9 2 1 , ▁at ▁a ▁conference ▁of ▁the ▁Direct ors ▁of ▁Music ▁of ▁the ▁Navy , ▁Army ▁and ▁Air ▁Force , ▁held ▁at ▁Kn eller ▁Hall , ▁it ▁was ▁decided ▁that ▁the ▁B ▁ten or ▁sa x oph one ▁would ▁officially ▁replace ▁the ▁B ▁bar it one . ▁H . ▁E . ▁Ad kins ▁states ▁that ▁this ▁was ▁due ▁to ▁bar it one ' s ▁“ lack ▁of ▁character ▁and ▁its ▁in effect iveness .” ▁In ▁addition ▁to ▁the ▁removal ▁of ▁the ▁bar it one , ▁the ▁string ▁bass ▁was ▁also ▁omitted . ▁At ▁this ▁time , ▁it ▁is ▁not ▁known ▁why ▁the ▁string ▁bass ▁was ▁removed . ▁It ▁may ▁simply ▁be ▁that ▁school ▁bands ▁did ▁not ▁incorpor ate ▁it ▁( as ▁is ▁largely ▁the ▁case ▁today ). ▁It ▁may ▁also ▁be ▁that , ▁since ▁the ▁string ▁bass ▁was ▁marked ▁ad ▁lib ▁by ▁Hol st , ▁Bo ose y ▁& ▁Haw kes ▁did ▁not ▁feel ▁the ▁need ▁to ▁include ▁it . ▁Inst ru ments ▁added
