Other blues progressions edit
There are several variations on the standard blues form, some of which may vary in length. Country blues performers often adjusted the duration of the individual four bar phrases in order to accommodate lyrics or vocal performance.[1] Other more symmetrical forms have also been used, although with far less frequency than the twelve-bar standard.
Eight-bar blues edit
One variation is the eight-bar blues.
Sixteen-bar blues edit
Another variation is the sixteen-bar blues. A famous example of a sixteen-bar blues is George Gershwin's "Summertime", which is in the minor mode.
