Watch the Alternate Blues Forms online guitar lesson by Jeff McErlain from Blues Survival Guide: Rhythm Edition

The minor blues and 8 bar blues forms are hugely important and can really switch up the sound of a set. One of the problems with blues bands and blues jams is that they can devolve into a basic 12 bar shuffle on every tune. That is very difficult to listen to for a whole evening and something BB King, or Stevie Ray would never do. There are many examples of a minor blues such as "The Thrill is Gone", "Chitlin's Con Carne", "All You Lovin" and Zep's "Since I've Been Lovin' You". The classic 8 bar blues is "Key to The Highway" a classic version of this one and my intro to the song and form is on the Derek And The Dominoes record, Layla and Other Assorted Love Songs.
