In this lesson, we will learn how to derive an Augmented chord and 2 types of Suspended chords.
These scales can be derived from a Major Scale. And yet again, the Major Scale I am using for explanation is the same old C Major Scale!
An Augmented Chord is quite similar to a Major Chord with the only difference of a raised 5th degree in the scale interval (1-3-5#), whereas a Major Chord Triad interval is 1-3-5.
An Augmented Chord creates a tensed tone and won’t sound that good to our ears and will always have that strong tendency to resolve to a much relaxed sounding Major or Minor Chord.
And the formula for building an Augmented Chord is 1-3-5#
Applying this formula on the C Major Scale gives us a C Augmented Chord as C – E – G#
An Augmented chord is denoted as C Aug or C Augmented.
Suspended or Sus Chords (as they are popularly known) have unconventional scale intervals, wherein a minor 3rd (1-3b) or a major 3rd (1-3) is replaced with a major 2nd (1-2) or a perfect 4th (1-4).
Since there is an absence of a minor 3rd or a major 3rd in this chord, it creates a tensed sound just like an Augmented chord, but at the same time the semi-tone (or minor 2nd) interval between 1st and 2nd or 4th and 5th degree of notes gives rise to a dissonant tone – not so soothing to our ears.
There are mainly 2 types of Suspended Chords
- Suspended 2nd
- Suspended 4th
Suspended 2nd Chord
In a Suspended 2nd Chord, the Major or Minor Third interval is replaced with a Major Second note.
Formula for building a Suspended 2nd Chord is 1-2-5
By applying this formula on the C Major Scale, we get a C Suspended 2nd or C Sus 2 chord as C-D-G
Suspended 4th Chord
In a Suspended 4th Chord, the Major or Minor Third interval is replaced with a Perfect 4th note.
Formula for building a Suspended 4th Chord is 1-4-5
By applying this formula on the C Major Scale, we get a C Suspended 4th or C Sus 4 chord as C-F-G
I hope you found this lesson useful in understanding Augmented and Suspended Chords clearly. I will be coming up with more interesting lessons and articles in my upcoming posts, so stay tuned!
How often have you come across Augmented and Suspended chords while playing guitar? Have you experimented which chords sound good with these “tensed” sounding chords?
