While tunes such as "Now's The Time", "Billie's Bounce", "Au Privave", "Barbados", "Relaxin' at Camarillo", "Bloomdido", and "Cool Blues" were based on conventional 12-bar blues changes, Parker also created a unique version of the 12-bar blues for tunes such as "Blues for Alice", "Laird Baird", and "Si Si."
Додека песните како :"Now's The Time," "Billie's Bounce," "Au Privave", "Barbados", "Relaxin' at Camarillo," "Bloomdido," и "Cool Blues" биле основани врз вообичаените, Паркер исто така создал необични блуз верзии со 12 тактови промени за песни како што се: "Blues for Alice", "Laird Baird", и "Si Si".
