The following chart gives a comprehensive list of chord formulas, together with an example based on the C Scale:
*indicates that a note is optional.
A double flat bb, lowers the note’s pitch by one tone. A double sharp !, raises the note’s pitch by one tone. The chart lists chord formulas for all the different chord types learned and a few additional ones. This is how it works:
B7 is based on the dominant 7th formula ( I - III - Vb - VIII ), and the B scale:
Thus: I II III V b VIII
Major scales not studied in this book can be derived by following the interval sequence tone - tone - semitone - tone - tone - tone - semitone. (See Lesson Nine).
