How can I create a blues song?

To create a blues song, start by writing lyrics that express feelings of sadness, struggle, or longing. Use a simple chord progression like the 12-bar blues and add a melody that reflects the emotional tone of the lyrics. Incorporate elements like call-and-response vocals and bluesy guitar riffs to give the song an authentic blues feel. Experiment with different tempos and rhythms to find the right groove for your song.
