Blues emerged in the South starting as early as the 1910’s. It is known distinctly for both lyrical content and instrumental style – two things that were important in the genre. Lyrics usually expressed emotions, and were often times used to tell sad stories through song. As far as instrumentals, many artists relied on the use of guitars or pianos. 12 Bar Blues, a sequence consisting of three different chords, became popular a little later. Artists that shaped this genre include Bessie Smith, Ida Cox, B.B. King, Skip James, and more.
