The circle of fifths is the way the 12 musical notes of the chromatic scale are arranged following a sequence of perfect fifths (7 semitones). It helps visualizing relationships between notes and better understanding diatonic harmony.
What's An Inverted Chord?
An inverted chord is a chord whose notes are stacked in a different order. In other words, the notes of a chord, whether it is a triad (containing just three notes) or a tetrad (built with four notes), can be reshuffled in a different way.
The name of the chord will still remain the same, but the bass will not necessarily the root note. This is the lowest note (the bass note) that determines the name of the inverted chord. So, chord inversion simply refers to which note is in the bass. You will find in this article some example for a better understanding of what are inverted chords.
What is an Interval ?
An interval is the distance between two notes, each one is represented by a number (1,2,3,4,5,6,7...) and a prefix related to its quality ("M" for major, m for minor, "P" for perfect, "d" for diminished and "A" for augmented). There are five different qualities.
An interval can be melodic, when the tones are successive (played one after the other) and harmonic, if the notes are stacked (played simultaneously). Knowing the name of each interval on guitar and on any other instrument is very important.
Intervals are essential elements of music theory. Intervals are very useful to understand how chords and scales are built. This article shows you how to make the difference between them.
What is Quartal Harmony?
To enrich and modernize the harmonization of a piece it is common to use fourth chords. They can replace some original chords to bring more melodic freedom into improvisation and more tension in harmony.
Since the late 1950s, harmony in fourths has played a very important role in the development of modern jazz. Musicians and composers have used a lot the quartal harmony.
Among them, the great American pianist McCoy Tyner, who, is a master in the art of playing quartal chords. Mike Stern, Herbie Hancock, Chick Corea, Bill Evans and Kurt Rosewinkel have also used this technique.
In this lesson with tabs and shapes, we will see how to build chords in fourths, how to harmonize the major scale with and how to use them in comping.
