Watch the Slash Chord Formulas online guitar lesson by Brad Carlton from Guitar Lab: Slash Chord Formulas
This course is designed to equip you with the theoretical knowledge, fingerboard visualization, and productive redundancy when building extended chords. I use the term productive redundancy to refer to the phenomenon that occurs in music where one piece of information can serve you in many different ways. When you're dealing with harmony this occurs quite frequently. You will learn how to utilize sus2, sus4, major, minor, augmented, and diminished chords as building blocks for more extended harmonies. You will also learn how to visualize inversions of any chord along the string axis and also how to modify any chord to create other chord qualities. The principle of chord synonyms will be explained as well as the concept of "cross-thinking". In addition, the information in this course is not restricted to just rhythm guitar. You will be able to use all the chord voicings and arpeggios as a a framework when soloing.
