Theory I.9: Literally All Possible Triads!



Once you have memorized all of the major triads, you have done most of the work toward knowing any possible triad that anyone could possibly ask you to name.  The only thing left to do is to learn how to modify those major triads into the other three types of triads:  Minor, Diminished, and Augmented.

One other slightly different aspect of this skill is to recognize the changes when you encounter a triad that isn't major.  You have to be able to compare it to your memorized major triad and recognize the changes that made it into the chord your are seeing.  This isn't terribly difficult since the root of the chord is nearly always obvious and the changes are any note that doesn't match your memorized major chord.  :)

Chords and triads are two terms that are used somewhat interchangeably here.  This works as long as all of your chords are triads, but later in the semester, we will be talking about 7th chords.  At that time, we will have to specify between triads (with three notes) and 7th chords (with four notes).  9th chords (with five notes) are also possible, as are 11th and 13th chords, but it's helpful to think of those later ones as being added into the smaller chords.  We'll talk more about this later in the course...
