The Mississippi Delta is the distinct northwest section of the state of Mississippi that lies between the Mississippi and Yazoo rivers. Technically not a delta but part of an alluvial plain, created by regular flooding over thousands of years, this region is remarkably flat and contains some of the most fertile soil in the world.
The harmonica, also called harp, French harp, and mouth organ, is a free reedwind instrument used primarily in blues and American folk music, jazz, country music, and rock and roll. It is played by blowing air into it or drawing air out by placing lips over individual holes (reed chambers) or multiple holes. The pressure caused by blowing or drawing air into the reed chambers causes a reed or multiple reeds to vibrate up and down creating sound. Each chamber has multiple, variable-tuned brass or bronzereeds, which are secured at one end and loose on the other end, with the loose end vibrating and creating sound. (more)

Slide guitar or bottleneck guitar is a particular method or technique for playing the guitar. The term slide is in reference to the sliding motion of the slide against the strings, while bottleneck refers to the original material of choice for such slides, which were the necks of glass bottles. Instead of altering the pitch of the strings in the normal manner (by pressing the string against frets), a slide is placed upon the string to vary its vibrating length, and pitch. This slide can then be moved along the string without lifting, creating continuous transitions in pitch. (more)
