Mixolydian Mode Introduction.

This is probably your first introduction to modes. It is ok to think of them as a type of scale and just learn the shape, but be aware that there is more to learn about modes in the future.

The mixolydian mode (or 7th chord scale) is very common in blues and rock music. It is the scale from which the 7th arpeggio comes from, so it is used mostly in conjunction with a 7th chord, such as a G7.
