The following piece is an example of the 12 Bar Blues, which is a musical form central to the African American music tradition. It uses a pattern of chords that repeats every 12 bars and may be played in any key. This one contains many accidentals, so take it slowly at first to be sure you are playing the correct notes. Whenever you are learning a melody which contains new notes, play slowly and sing the names of all the notes out loud as you play. Listen carefully as you do this, and try to sing the same pitch as you are playing.
