I will be posting a primer on basic harmony (i.e. triads) at a later time so watch out for that. In the meantime for you more advanced songwriters, I’m going to talk a little about where you go when you’ve finally mastered your simple major and minor triads. A lot of great and famous songs have been written solely using those basic triads so let’s not diminish them, but if you want to expand your palette of sounds and chords to add to your songs, you should try to get beyond those basic triads. Here are some of the other important chord types that any aspiring songwriter should keep in their arsenal:
1. Dominant 7 (written as C7, F7, etc): This is a major chord with an added note that is a whole-step below the root note. If the root note is C, the chord would be:
C-E-G-Bb
This chord is used generally to toughen up a chord sequence and make it sound less “settled”.
2. Minor 7 (written as Dm7, Am7, etc): This is a minor chord with a note a whole-step below the root note. If the root note is C, the chord would be:
C-Eb-G-Bb
This chord makes a minor chord sound less “minor”. Some people say this chord sounds “jazzy”.
3. Major 7 (written as Cmaj7, Fmaj7, etc): This is a major chord with a note a half-step below the root note. If the root note is C, the chord would be:
C-E-G-B
This chord is used frequently in ballads and slower tempo music.
4. Minor/major 7 (written as Dm/maj7, Am/maj7, etc): This is a minor chord with a note a half-step below the root. If the root note is C, the chord would be:
C-Em-G-B
This chord is not as commonly used in popular music, but it can be used when you are trying to write music that sounds unsettled or tense.
5. Major 6 (written as C6, F6, etc): This is a major chord with the sixth note of the scale added. If the root note is C, the chord would be:
C-E-G-A
This chord can be used to bring a slightly jazzy feel to a chord progression that uses major chords. A “minor 6” chord can be created too by adding the sixth to a minor chord, but it is extremely rare in popular music.
6. Suspended Second (written as Dsus2, Asus2, etc): This is a chord that is neither major or minor (as are any “suspended chord). It is created by taking the third and replacing it with the second note above the root note. If the root note is C, the chord would be:
C-D-G
This chord adds mystery, color and movement to a chord progression.
7. Suspended Fourth (written as Dsus4, Asus4, etc): Again, as a suspended chord this chord is neither major nor minor and is created by replacing the third and replacing it with the fourth note above the root note. If the root note is C, the chord would be:
C-F-G
This chord is more tense than the sus2 chord – it is a chord that has a strong need to be “resolved” (by either going to the major 3rd or minor 3rd).
8. Minor Add Ninth (written as Dmadd9, Amadd9, etc): This chord is a minor triad with an extra note that is the second note in the minor key added an octave above the root. If the root note is C, the chord would be:
C-Em-G-D
This chord is used to make a minor chord sound even more sad.
9. Major Add Ninth (written as Cadd9, Fadd 9, etc): This chord is a major triad with an extra note that is the second note in the major key added an octave above the root. If the root note is C, the chord would be:
C-E-G-D
Conclusion: There are also augmented and diminished chords, but they are not very common in popular music so this discussion will omit these chord shapes. Try incorporating some of the above chord shapes into your chord progressions to see how they add color and interest to your progressions. Try to really absorb the sound of these chords, so that you can recognize them when you hear them on the radio. Let me know if you have found other uses for these chord shapes that I haven’t discovered!
