As you may know from past lessons, tertian chords are built on thirds.

This is majority of the chords you’ll play since almost every common chord (like major, minor, dominant, diminished, augmented, and even most altered chords) are built on thirds.

In this post, I wanted to provide a quick refresher on some of the most common tertian chords.

C major

C minor

C diminished

C augmented

C major 7

C minor 7

C dominant 7

C# diminished 7 (my image program doesn’t do “double flats” so I’m going to put the C# diminished 7 below). Note: The C diminished 7 chord is C + Eb+ Gb + Bbb (aka - “A”)

C half diminished 7

C augmented major 7

C augmented 7

C major b5 (flat “5″)

C minor major 7

C dominant 7 (b5)

Welcome back! It looks like you're a regular! Thanks for your support and keep coming! (Getting updates yet?)

“The B13 Chord”

This is what we call a dominant 13th chord (but it does have some notes omitted). Here it is below:

Bass = B

Right hand = A + C# + D# + G#

Because there is a “G#”, we call this chord a 13th. A few days ago, we discussed the “extended tones” concept. If you don’t understand why G# is the 13th tone of the B major scale (and also the 6th tone in the lower octave), check out the e-mail that I sent a few days ago, ok?

If you don’t know the B major scale, then you need to check out some of our free lessons on “major scales.” My 300-pg course also covers major scales and 7th, 9th, 11th, and 13th chords. Visit:
