jump blues
doo - wop
electric blues
bluegrass

1. ________ were a descendant of the big bands, featuring groups of five or six players

electric blues bands
blues crooners
honky - tonk bands

Explanation:

For question 5: In the late 1940s, Delta blues musicians moved to urban areas and adapted their sound with electric instruments, creating electric blues. Jump blues is an up-tempo blues style focused on dance, doo-wop is vocal harmony-based, and bluegrass is a distinct string-based folk style unrelated to Delta blues' electric evolution.
For question 6: Jump blues bands (the missing term, as it is the correct option not fully shown but implied by context) evolved from big bands, scaling down to 5-6 player groups while retaining the brass and rhythmic focus of big band blues. Electric blues bands focused on amplified instruments rather than big band lineage, blues crooners are solo vocalists, and honky-tonk bands are country-focused.

Answer:

1. Electric blues
2. Jump blues bands
