String Theory by Jimmy Brown
CHANGING COLORS
Adding depth with parallel major and minor keys
Jimmy Brown discusses an intriguing type of chord change that many composers have put to great use in countless major-key songs. It involves “borrowing” a chord from what’s called the parallel minor key to create a temporary harmonic detour and a surprise shift in musical color and mood that’s often used to impart a touch of sadness or melancholy to an otherwise happy -and predictable- sounding progression.
