Last updated on: 2009-08-19 2:10 PM

A dominant seventh suspended second chord is composed using a root/1st, major 2nd, perfect 5th and minor 7th (or R/1-2-5-Flat symbol7) intervals played simultaneously. Generally written as C7sus2 or C7(sus2), it is good practice to simply use an uppercase C followed by a superscripted 7sus2 to represent it in writing (ie: C7sus2).

The dominant seventh suspended second chord is enharmonic to a minor seventh suspended second chord as there is no 3rd degree present in either, and both have a minor 7th interval. Like the suspended second chord, it's quality (ie: minor or dominant) is implied by it's resolution (if any) however in this instance, resolution is either minor or dominant, not major (this is due to the minor 7th being present in both). As an example, if you were to play a D7sus2 followed by a D7, the implied quality would be dominant because the major 2nd (suspended 2nd) is resolving to a major 3rd one whole step higher, while the minor 7th remains. Alternatively, if you were to play the same D7sus2 chord but this time follow it with a Dmi7, it's implied quality would be minor because the major 2nd is resolving to a minor 3rd one half step higher, once again the minor 7th remains.

It is not necessary to resolve the dominant seventh suspended second or the minor seventh suspended second chords, it is mearly a tonal tool we can use if required.

Dominant Seventh Suspended Second Chord Voicings

The chord voicing's below are not shown with any particular root note, they are shapes which can be moved around the guitar neck freely using the root note (circled dot) as your navigator. See example below.

  • How to use
  • As an example, let's say you require a D major chord
  • After playing all the chord voicing's, you decide on voicing #2
  • Voicing #2 has it's root on the 5th string so you need to find the D note on this string
  • You click the notes on the neck reference chart tab and find the D note is on the 5th fret (5th string)
  • You now play D major using voicing #2 on the 5th fret
  • Use the Octave chart tab to help you remember which notes are where
  • Use the Chord chart help tab if your a beginner at reading chord boxes

Using octaves to learn notes on the guitar neck

  1. First determine which chord you require, let's use a B major chord in this example.
  2. We know the root note is B, (if it were an A major chord the root note would be A and for Cma7 it would be C, etc etc)
  3. Using the notes on the guitar neck chart, find the B note on the 6th string, 7th fret.
  4. Now using the major chord voicing's chart, look for voicing #4 which has it's root note on the 6th string and play it.
  5. Now lets find a B major chord on the 5th string using voicing #2
  6. You already know the B note on the 6th string 7th fret, now track back to the B on the 1st string 7th fret, then to the B on the 3rd string 4th fret, and finally to the B on the 5th string 2nd fret and play voicing #2 major chord.
  7. Remember, learning and memorizing notes, chord voicing's and scales in this way will improve your playing skills, theoretical knowledge and desirability as a band member.
