The bass is the largest and deepest voice of recorders available in ABS plastic. It is F fingered with a general range of the first F below Middle C to G'' (two octaves above Middle C.) Size and weight of differing models vary dramatically. Most basses sport a bocal (much like as is seen on the bassoon,) hovever a few models incorporate the bent-neck design. Both types are pictured on this page. The bass is almost always keyed in several places, and, ironically, requires less of a finger spread than does the tenor.
