You 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.
If the basic sound of jazz is based on tetrad chords (four-note chords), it is common to extend them with other tones. These other notes forms the upper structure of a chord which includes 9th, 11th and 13th. Adding extensions to chords help to get off the beaten tracks and provides some new harmonic colors to your playing (chord soloing, comping, and arrangement). This lesson provides you useful extended major 7th chord shapes to apply to your playing.
Basically, major 7th chords are made up of a root (1), third (3), fifth (5) and seventh (7). They can be extended with a ninth (9), a sharp eleventh (#11) and a thirteenth (13).
The notes in yellow in the chart below can be added to the basic structure of a major 7th chord to extend it. Therefore a C major 7th chord can become Cmaj9, C maj7#11, Cmaj13.

Major 6 and minor 6 chords are often used in place of major 7 and minor 7 chords when comping over jazz standards. That's why it is very important to be able to play them on the guitar neck. There are two main types of chords that contains a sixth, M6 and m6. These chords are made up of 4 notes and built with the interval patterns :
- R-3-5-6 for the major 6 chords.
- R-b3-5-6 for the minor 6 chords.
In this post you will see how to play these major 6 and minor 6 chords (root and inverted positions) using 24 guitar diagrams and voicing charts.
The origin of the "so what chord" name would be due to its use by the jazz pianist Bill Evans in the modal tune "So what" by Miles Davis. This is is a cool and modern sounding chord voicing often used as an alternative to quartal voicings. It is built with a fourth chord on the bottom (3 perfect fourths stacked) and a major third added on the top. This particular chord was originally played on a piano, but it is quite interesting to play it on the guitar to support rhythmically and harmonically a soloist over a modal tune.
This jazz guitar rhythm lesson with tabs and diagrams provides you some interesting ideas of comping inspired by McCoy Tyner's playing on "impressions" by John Coltrane.
"There Will Never Be Another You" is a popular song by Harry Warren (music) and Mack Gordon (lyrics). It is one of the most known jazz standards and an indispensable study for any jazz guitarist. This jazz guitar comping lesson provides you different chord positions (drop 2, inverted, rootless and extended chords) on the top four strings of the guitar to comp over this jazz tune. By the way, it will also give you some new ideas to support harmonically a soloist. Indeed, you may even try to apply these chord voicings to the tunes you are used to play.
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 we will see how to build chords in fourths, how to harmonize the major scale with and how to use them in comping.
