see the attached files and choose 2 singers from every generation listed, so total is 10 singers ( 5 men singers and 5 women singers).
first generation: 1800-1910 second generation: 1910-1935 third: 1935-1960 fourth: 1960-1985 fifth: 1985-2010
write a small theses for every generation about why did you choose these two singers they have to be connected in some way, for example the effect of their songs on the people.
like i said for each generation 2 singers and for each generation a small thesis about them, so there will be 10 thesis.
every source you use to get information about the singers you have to put it at the end for example use primary source and secondary source, and put them all.
