I played three different segments of three different styles of songs in three different keys all on the same harmonica.

We have a C harmonica and I played Catch the Wind, the Donovan folk song in C. Then I played an excerpt of Stevie Ray Vaughan's Cold Shot and that was in a G Blues and then I played a little Santana Black Magic Woman and that's in D minor. These are different keys, different styles of songs and we played them in different positions. That's the only way we can do it to play it on one harmonica.
