Musical beginners (and many of us who aren’t) often wonder how to determine the key of a song. And we also wonder "how do you make -- and how do you know how to make -- a C7 (C Seventh) or GMaj7 (G-Major-Seventh) or a C+ (C Augmented) chord?" Let's start with the simplest key, the key of C. We'll see how to form chords in this key, then go on to other keys. The next file, Other Keys, takes the theory in the key of C and extends it to other keys. The file after that, Chord Formation, then explains how to form chords using the theory explained so far. How to determine which chords can be used in which keys, Chords in Keys, is next. That's followed by some theory of Chord Progressions, and the Circle of Fifths, a way of remembering which sharps and flats are in which keys. Table 2 is a list of notes played in the major keys. Table 3 is a list of formulas for forming various chords. Table 8 is a list of important chords in each of the major keys. Table 9 and Table 10 list several chord progressions.
