What is the theme of " The Weary Blues" by Langston Hughes?

The central theme of “The Weary Blues” concerns the resilience of the archetypal “common” person who has times of despair or despondency. Music serves as a means of relieving pain or anxiety. The poem transcends the limitations of race, as all people have used music and poetry as a means of getting through bad times. The cause of the blues singer’s sense of isolation, loneliness, pain, and trouble is deliberately vague. His inability to identify the exact cause of his trials and tribulations, or the narrator’s unwillingness to speculate upon it, enhances the universality of those feelings. The unspoken but evident complexity of the interrelationship between the player and his piano and the narrator and the musician corresponds to the complexity and interrelatedness of musical and poetic traditions. The poem, in its unconventional thematic and formal structure, advocates an equal acceptance of the two.
