Unit 7 is the âstress testâ of Flawless Ear Training. Here, youâll master major sixths and augmented triads, tackle the IâIIIâVâI pattern, and push all previous skillsâtriads, inversions, quartal/quintal harmony, and block patternsâunder real musical pressure. With less guidance and more independence, your ear becomes flexible, confident, and ready for advanced harmony.
