One of the explanation is given by the structure. Indeed, there are no semi-tones in it. It is easy to play on the guitar and it can be used in a whole lot of very different contexts. This lesson will show you eight ways to use the minor pentatonic scale over a dominant seventh chord. The principle is easy to understand, this consists in playing the minor pentatonic scale starting on each tone of the Mixolydian scale (1, 2, 3, 4, 5, 6, b7). This method helps to highlight certain notes and brings interesting colors to your jazz guitar lines depending on you want to play outside or inside.

  • Triad Arpeggios - Guitar Lesson For Beginners

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".

  • What is The Tritone Substitution - How To Use It

    Tritone chord substitutionWhat is The Tritone Substitution?

    One of the most popular jazz chord substitution is the tritone substitution sometimes referred to as the dominant chord substitution. The most used is to replace the V with a dominant 7th chord whose root is a tritone below. Example with G7 (V), which can be replaced by Db7 a tritone (Three whole-steps) away. Thus giving two chords that have two notes in common. The 7th of G7 (F) is the third of Db7 and the third of G7 (B) is the seventh of Db7. The inversion of the 3rds and the 7ths between the original dominant chord (V) and the substituted dominant chord (bII7) is the main feature of the tritone substitution.

  • What's a Half-Diminished Chord (m7b5)

    What is a half diminished chordYou surely know what are major chords, minor chords, seventh chords and diminished 7th chords ? But you may be wondering what half-diminished chords are ? In music, the most encountered chords are major and minor chords. These are the basis of the Harmony. Seventh chords (m7, Maj7 and dom7) are also widely used, particularly in jazz and blues music. When a guitar student start to take an interest in jazz, he can sometimes find chords with a little barbaric names such as diminished 7th chords, augmented or even half-diminished chords (m7b5). This article will explain you what are m7b5 chords, how to play them on the guitar and how to apply them in common harmonic contexts as major and minor II-V-I progressions.

  • List of Musical Intervals - Music Theory

    Intervals

    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 is very important for any musician, they 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.

  • Chords in Fourths - Quartal Harmony

    Quartal harmony - Chords in fourthsWhat 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.

  • What's a II-V-I Chord Progression

    What's a II-V-I chord progressionWhat Is The II-V-I Progression?

    The II-V-I sequence is the most common chord progression used in jazz music but also in a whole number of styles of music as pop, rock, blues, country.

  • How To Harmonize The Major Scale In Thirds?

    How to harmonize the major scaleOne 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.

  • What Are Guide Tones and How to Use Them

    What are guide tonesWhat Are Guide Tones?

    They are the notes in a chord which leads or gives harmonic pull toward the next chord, these are an excellent way to study and absorb the sound of any chord progression. Guide tones are used to outline chord progressions in an improvisation. They are most of the time the 3rd and the 7th because this is what determines whether a chord is major, minor, or dominant. 

    You will learn how to target important notes in each chord by working on guide tones. This jazz guitar lesson explains how to solo over common jazz progressions using and connecting the guide tones.
