A dyad is a two-note chord, a pair of notes played at the same time. These two notes are separated by an interval. Considering there are different types of intervals, there are therefore different types of dyads.
What's an Interval in Music?
An interval is the distance between two notes. It can be melodic or harmonic.
Is a Dyad can be considered a Chord?
A chord must contain, at a minimum, 3 notes. As its name implies a dyad is made of only two pitches. So, a dyad is considered as being an interval, not a chord.
What's a Diatonic Scale?
A diatonic scale is built with of half and whole steps. The term diatonic comes from the ancient Greece. In western music a diatonic scale is based on five whole steps and two half-steps that can be ordered in many specific ways. The best known is the diatonic major scale based on the formula W - W - H - W - W - W - H which means Whole-Step | Whole-Step | Half-step | WholeStep | Whole-Step | Whole-Step | Half-Step.
What's An Inverted Chord?
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 different order. 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 here some example for a better understanding of what are inverted chords.
Triads are one of the first harmonic tools to study. They are very useful for comping and chordal enrichment. Learning close and open triad voicings increase your harmonic knowledge and at the same time help you discover your fretboard. In this lesson you will see the main triad chord shapes including root positions and inversions. You will also find some ideas on how to use triads over a II V I sequence, in order to create interesting melodic movement in your comping.
A major chord is built with three notes namely root (1), major third (3) and fifth (5). These three tones represent the structure of the major chord. The same holds true for minor, diminished and augmented chords. In this guitar lesson you will learn how to play a major chord in closed and open triad voicings (also known as spread voicings).
Arpeggios are surely the most important devices to master when you want to start improvising. Every jazz players use arpeggios in their improvisations. Great guitarists, all kinds of styles use arpeggios : John Scofield, Kurt Rosewinkel, Birelli Lagrene, Django Reinhardt, and many more. Arpeggios are played extensively because they use only the notes found in a single chord. Therefore, they create a more harmonized sound when played with their corresponding chord. Arpeggios are very helpful to easily outline the chord changes. This lesson is focused on the most basic form of arpeggios made out of three notes called "triad arpeggios".
One of the fundamental theoretical elements to understand music is the harmonization of the major scale. Harmonizing scale is building chords with notes. For this, you have to stack thirds (It is also possible to harmonize the major scale in fourths).
If you are wondering why thirds and not seconds or sixths for example, the reason is mainly historical: our music today is based on harmony in thirds. Once you have read this lesson, you will be able to find the tonality of a song simply by looking at its chords, you will know which scale to play on which chord progressions.
How To Play Triads On Guitar?
Mastering Triads on the guitar is necessary for any guitarist who want to expand his fretboard and theory knowledge. These chords are not really considered as jazz chords because of their basic sound, but they can be efficient tools for comping and chord soloing. Indeed, the strong point of these chords is the simplicity of learning and playing. You will find in this guitar lesson 48 chord shapes to play major, minor , diminished and augmented triads.
