In the poem, the poet highlights the lost and pathetic state of German Jewish people who had to flee their homes and seek refuge in other countries due to the rise of Hitler and Nazism, laws depriving them of their right to live, holocaust, concentration camps. Blues in the title signify the African-African musical genre that originated at the end of the 19th century and has a sad, melancholic tone, which is the tone of this poem. They sing of their agony and pain of homelessness.
