It would say that the technique that was discontinued during the swing era was Collective improvisation (option B) This might be because improvisation was connected to Jazz and Free Jazz music. Swing jazz is based on the off-beat or music pulse.
Is this asking whether this is true of false? If so, then you'd be correct. <span>There are over two dozen different forms of jazz music.</span>
856 + (19 - 3 - (6 + (5 - 3) - (2 + 1) + (5 - 3) ) ) = 856 + (16 - (6 + 2 - 3))
= 856 + (16 - 5)
= 856 +11
= 867
