There are two versions of the St. Louis Blues up for you this week. The first is by blues singer Bessie Smith; the second by Louis Armstrong with a group of musicians.
- Is the melody altered in his version? Can you recognize the melody?
- Armstrong is improvising on the melody. What does improvisation mean? Does it mean you just do anything at all that comes into your head, or is there some kind of a structure that you are working within?
