Theory

This chord theory lesson focuses on how to transform a dominant 7 chord (drop 2, drop 3 and related inversions) into a rootless ninth chord by replacing the tonic (1) with the ninth (9). 

This technique will help guitarists expand their harmonic knowledge and also explore their neck in more depth. This can be a useful trick when composing or for chord melody arrangements.

In this guitar lesson you will learn how to transform a diminished 7 chord into a dominant 7 and also a minor 6 chord either by lowering or raising only one note in order to get a smooth transition. Check the GUMROAD shop to get the free PDF.

Lesson by Mike Hayes

In this video Mike explains what is the relative minor chord and how to use it to create your own chord melody parts on guitar. This step by step lesson will help you understand how this major and relative minor tonal relationship can open up a whole new world of sonic possibilities.

This theory lesson for guitarists covers one the most common question asked by beginner musicians : what's the difference between a dominant seventh and a major seventh chord.

Hexatonic scales are made of six notes, even if you can get them from any pentatonic scale (by adding one note) or diatonic scale (by removing one note), the most popular are the blues scales (major, minor), the augmented scale, the whole-tone scale, the tritone scale and the Prometheus scale.

This guitar lesson with formula charts and diagrams covers them in details and will you help to better figure them out.

This music theory cheat sheet file explains effectively how drop 3 chords are built. You can download the printable PDF file (better quality) for free (or make a donation to support this website) following this link.

This blog post contains free cheat sheets (infographics) for guitar players about the Dorian mode. You will find useful information on how to play chords, arpeggios and minor licks directly related to this minor scale.

Whether simple or compound intervals are a very important part of  music theory. Knowing them allow understand how scales, arpeggios and chords are built. Intervals are useful tools to visualize the notes and understand their relationships on the guitar fretboard. This lesson with downloadable pdf, guitar shapes and theory will help you better figure them out and play them on guitar.

What Scale To Choose For Improvising?

One of the most common question a beginner asks when he wants to start improvising on guitar is : Which scale to choose over which chords? However, there is a lot of scale and a lot of chord, it is easy to get lost. That's why it is important to make the relation between them, trying to understand what is the appropriate scale that fit the chord and vice versa. 

This guitar lesson provides the seventeen most important scales with shapes and formulas to know for improvising over the most used chord types in jazz music (major, minor, dominant and diminished).

Dominant 7 flat ninth chords (7b9) are generally related to the fifth mode of the harmonic minor scale known as Phrygian dominant scale, which makes it the most obvious choice for improvising over 7b9 chords. However, we will see in this article that there are many other options.

Pentatonic scales are scales with five notes per octave. They are frequently used in music all over the world. The word "pentatonic" comes from the Greek word "pente" meaning five and "tonic" meaning tone.

Talk of "the" pentatonic scale generally make reference to the major pentatonic scale and its relative minor. It's a mistake, indeed there are many types of pentatonic scales (Egyptian, Ritusen, Man gong, Altered, Locrian...).

Pentatonic scales are considered earlier than heptatonic scales (seven-note scales) and can be divided into two categories :

• Containing semitones (hemitonic)
• Without semitones (anhemitonic)

The purpose of this post is to propose some tips and ideas for practicing and develop pentatonic scales.

What's a Tritone Substitution?

The tritone substitution is one of the most common substitution found in jazz. The basic application of a tritone chord substitution is to take any 7th chord and play another 7th chord that has its root a tritone away from the original. This guitar lesson demonstrates how you can play scales and arpeggios starting from the b5 (a tritone away) of the V7 chord in a II V I chord progression. This way you will highlight altered tones as the b9 and the #11. 

Dominant seventh chords are the most important features in music, you can find them in many styles of music, especially in blues and, of course, in jazz. In this lesson, you will see how to construct drop 2, drop 3 and drop 2 & 4 dominant seventh chords, what is their harmonic function and how to play them on guitar.

What Are Drop 2-4 Chords?

Drop 2 and 4 chords are created by dropping down an octave the second and fourth note of a seventh chord in close position. They can be very important tools for composition and arrangement. This lesson with diagrams provides useful explanations on how to build and play drop 2 & 4 chords on guitar.

What's a Tetrad ?

A basic chord is built with three notes this is what we call "triad chords" or "triads". Tetrad chords aka "four note-chords" are simply chords containing four notes, “tetra“ is a Greek root meaning four. This means that tetrads are triads with an additional note which can be a major seventh (7) or a minor seventh (b7). 

Here is a list of the main musical scales and modes.
