"12 months in a year, 12 signs of the zodiac, 
12 bagels in a dozen, 12 bars in a Blues!"
—Wynton Marsalis

"You and your woman ain't gettin' along and you're in love.
You can't sleep at nights. Your mind is on her. That's the Blues.
You can't hug that money at night. You can't kiss it."
—John Lee Hooker

"Left hand oom-pah derivatives and comping variants are rather ubiquitous in jazz piano performance practice today, so one's assimilation of said proxy and protocol remains a factor in determining the extent of one's success in efforts of contrapuntal synchrony or the efficient delineation of tension harmony,

—Eric Lewis
