Song lyrics and vocals combine in musical composition, creating a dynamic musical piece. Chord progressions have the power to alter its mood, so it is crucial that listeners understand them fully.
To play guitar chords effectively, one needs the proper techniques and finger strength. Furthermore, being familiar with chord diagrams will also prove helpful.
Triads
Triads are essential tools for improving guitar playing. Consisting of three distinct notes arranged into an interval-based structure, these chords can be used in an assortment of ways to add variety to your playing. A C major triad, for instance, might sound upbeat while G minor chords might bring sadness or contemplation into play.
Triads can be divided into three main categories, Major, Minor or Diminished. Their quality depends on the distance between bass and soprano voices and doubled roots and/or open or close spacing of those roots.
Example: a G major chord contains roots of G, C and D; by moving the second and third notes respectively you will create an A minor triad.
Major
C major, F major, G major and A minor chord shapes will allow you to play an array of popular songs with ease; however, for something a little different you may also require other types of chords as well.
Triad chords are among the easiest chords to learn on guitar. Their three notes are separated by an interval of a third note and make for quick playing and understanding on this instrument.
Once you’ve learned these chords, experiment by playing them with various extensions to hear how they sound. For instance, add an Am7 chord into an Fmaj9 chord or leave out some notes from an Fmaj9 chord to see what happens – remember names are only guidelines; make your own music using different combinations of chords!
Minor
Minor key chord progressions can be soothing (George Gershwin’s “Summertime”), funky (“Brick House” by the Commodores), and rocking (“Disarm” by Nirvana). Furthermore, they are commonly employed by musicians when creating songs to express emotions such as sadness, fear, or vulnerability.
Minor chords differ from major chords by only consisting of root, third and fifth notes of a scale; as a result they feature more subdued tones than major chords.
Minor chords can also be modified using extensions known as “sus” and “add9”, such as the C9sus4 nineth chord with an added fourth note (also written C-F-G-B-D). However, changing its root note only makes an impactful statement when used within its proper musical context.
Power chords
Power chords are two note chords that are easy to play with practice, making them popularly used in rock music and orchestrated by Kurt Cobain in his songs; today they remain an essential part of rock.
Power chords differ from traditional triads in that they omit the third note, giving them an unusual versatility that allows them to sound either like major or minor chords depending on whether strumming is done up and down or vice versa. As such, power chords make for great guitar riffs which require both up and down strumming patterns.
When playing power chords, it is essential to mute any unused strings with your palm or fingers in order to prevent unwanted sounds such as ghost notes. This will prevent unexpected noises.
Chord diagrams
Chord diagrams can help you gain a greater understanding of how to play your favorite songs. They display all the notes within an individual chord, including any open strings. Furthermore, this tool shows which fret each finger should be on. Thick black lines represent each string while numbers indicate which fingers to use.
As well as standard chord symbols, you may come across additional Xs above strings to indicate mutes; and open strings, which corresponds with an “o”. When this happens, these should both be played.
Bar chords can be identified by a thick line extending over strings, with an indication of which finger to use to play it on its left-side chord diagram.
