jazz guitar chords
A new video has been uploaded on the youtube channel. It is a Barry Galbraith comping study named "Like someone". This is the last study from the Barry Galbraith book "Jazz guitar comping series, vol #3" published by Jamey Aebersold. Most of the accompaniments studies (comps) in this book are designed to accompany a melody or an improvised solo with bass lines like a pianist would do. It is a very great book to practice jazz comping guitar.
You will find on this page 5 exercises to learn to play different jazz guitar chord voicings over the most used chord progression in jazz, the famous II-V-I sequence.
Generally, when a beginner starts to learn to play guitar, he tackles open chords (up the guitar neck), those found in many popular songs. Then, come the bar chords (major, minor, dominant 7) a little hard to master. But all these chords do not have a very interesting sound and are not mostly used in jazz music. That's why in this lesson, (addressed to jazz beginners) we will take the main basic guitar bar chords (involves barring severral strings with one finger) to transform and enrich them so that their sonority is richer, exciting and better suited to jazz concept.
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), it 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.
If the most common tritone substitution involves two dominant chords, there are other chords that can be substituted as the vi chord, the ii chord, and the iii chord. You can substitute any chord which has its roots the flat fifth of the original chord. The type of chord used depends on the melody and the desired harmony. The tritone substitution can also change qualities from the chord it is substituting. Provided that the melody indicates no strong preferences for chord type. For example, dom7 chords can be played in place of minors. This could be subject of another lesson. Meanwhile this article is focused on dominant seventh tritone substitutions.
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.
