Adaptation from twelve-bar progression

Most sixteen bar blues are adapted from a standard twelve-bar progression, i.e.,

T T T T
S S T T
D S T T

by applying one of several formulae including the following:

Sixteen-bar progression -
extending variety:
first section extended (1a)
T T T T
T T T T
S S T T
D S T T
Sixteen-bar progression -
extending variety:
third section extended (1b)
T T T T
S S T T
D D S S
T T T T
Sixteen-bar progression -
repeating variety:
second section repeated (2a)
T T T T
S S T T
S S T T
D S T T
Sixteen-bar progression -
repeating variety:
third section's first half repeated twice (2b)
T T T T
S S T T
D S D S
D S T T
Sixteen-bar progression -
blend of extending and repeating varieties

Guide:

(1a) Twelve-bar progression's first tonic chords (bars 1-4) are doubled in length or repeated, becoming the first half (bars 1-8) of the sixteen-bar progression

(1b) Twelve-bar progression's last dominant, subdominant, and tonic chords (bars 9, 10, and 11-12, respectively) are doubled in length, becoming the sixteen-bar progression's 9th-10th, 11th-12th, and 13th-16th bars

(2a) Twelve-bar middle section (subdominant on bars 5-6, tonic on 7-8) is repeated, often along with its lyrical-melodic material

(2b) Transition from ninth (dominant) to tenth (subdominant) twelve-bar chord is repeated twice

(3) Transition from ninth (dominant) to tenth (subdominant) twelve-bar chord is repeated once; last tonic chord bars are doubled in length

Adaptation from eight-bar progression

Alternatively, a sixteen bar blues can be adapted from a standard eight bar blues by repeating each measure of the eight-bar progression and playing the result at double speed (doppio movimento).
