Jazz Chords In D Major
Magnhild Lachowicz
While these two shapes sit well on the fretboard, most closed position chords are tough to play, which is why we shuffle around the intervals of the chord to form new shapes on various string sets of the guitar.
Now that you have worked major chords with the lowest note on the 6th string, you are ready to move on to learning and practicing Maj7 chord shapes with the lowest note of each inversion on the 5th string.
Something to look out for when using the major scale: the 11 (F in C major) is a so-called avoid note for major chords because it is one half step above a chord note (the 3 or e). This does not mean you can not play this note but is rather disharmonic when you keep hanging on it or use it as a target note.
The 7 and 11 are omitted, which gives this scale a bit more basic and less colorful sound. Such a sound can be effective for major chords with a strong tonic function (like ending chords) or for traditional jazz styles like swing.
Notice that the function of a chord is also about the chord progression, so it is not just about the notes in the chord. That is also why you can find examples of Am7 being a subdominant chord in C major as well as other places where it is tonic,
When a song is in a major key then the great thing about that is that you have all the diatonic chords that I just showed you but you can also use the chords from the minor key with the same root, so in C major you can also use the chords from C minor.
This is not entirely coming from scales and is essentially more about voice-leading, but starting with a scale is a great way to get some things to work with, and then you can expand on that to get to some of the great sounds, but I will get to that later in the video.
The Fm7 chord is more often used as a way of getting from a subdominant chord to a tonic chord, so not as a part of a II V I. Often you will in fact see it as an Fm6 or FmMaj7, but I will get to that in a bit. Here it is moving coming from Dm7:
What I am talking about in this video, is also sometimes referred to as modal interchange, but that concept is, as far as I know, a lot wider, where this is much more specific to the key and more of a description of the type of harmony you come across in Jazz standards.
As I mentioned earlier then the minor subdominants are more a result of voice-leading than of chords from a scale, and in fact, it is mostly about one note that is moving, in C major that would be A moving down to Ab to G, which if you start with an F chord gives you:
The way to understand it is really just to think of it as a IVm triad, so in C major that is an F minor triad, with an added 6th but in this case, it is a b6 since that is a stronger leading note to take us down to the root, C. And In Jazz, we turn that into a Dbmaj7 chord and have progressions like this:
If you have any questions, comments, or suggestions for topics then, please let me know. Leave a comment on the video or send me an e-mail. That is the best way for me to improve my lessons and make them fit what you are searching for.
This is exactly how I used to think about chords and the progressions to jazz standards. For years I would memorize a series of chords names in one key and try to think through a scale for each one to create a solo.
The crucial piece of the puzzle here is ear training. You need to get your ears to the next level, i.e., ingraining the sound of each chord quality so you can immediately recognize it on the fly in any tune you play.
With any V7 chord you can imply the related ii-V. (Bb7 vs. F- Bb7) In other words you can approach these as two bar dominant 7 chords or as a two bar ii-V7. They essentially have the same function and can be used interchangeably.
Aim to have techniques for both shorter language (individual chords) vs. longer language (progressions) and mixing or combining the two. Remember, every larger progression is built from the individual chords.
The moment they hear a tune they recognize the sound of the chords, they can instantly identify common progressions by ear, and they have a wealth of language for the chords & progressions that occur in every tune.

In some chords, it is necessary to omit some of the notes in order to reduce dissonance within the chord. For instance, the 11th often clashes with the 3rd in 13th chords, so the 11th is generally omitted.
The chord books I have generally only remove one or two notes from a chord. But I want to know if there are any "rules" around what combinations of notes can or cannot be removed from a chord. What if we take this concept to it's logical extreme:
In classical theory, the necessity or lack thereof of a particular chord member is generally determined by the note's tendency to lead to another note. That tendency comes most often from the interval of an augmented fourth or diminished fifth. Enharmonically, those intervals are the same, but in context, they are not, and they resolve differently. In a "dominant seventh" sonority, the third and seventh of the chord form a diminished fifth if the third is below the seventh, or an augmented fourth if the third is above the seventh. In the diminished fifth, the upper note resolves down by step, and the lower note resolves up by step. In the augmented fourth, the upper note resolves up by step, and the lower note resolves down by step. What this means for the dominant seventh is that scale degree seven, the "leading tone," resolves up to tonic, and the chordal seventh, scale degree four, resolves down to scale degree three. Scale degrees one and three strongly imply the tonic chord of the key, so there is a feeling of resolution. In other seventh chords, the seventh still resolves down by step. It is possible in the dominant seventh to omit the root without changing the function of the chord. Often, then, what would have been the lowered ninth is added, providing another diminished fifth or augmented fourth (against the fifth of the chord). If I had a convenient way to draw all this out on a staff right now, I would.
In jazz, we don't always resolve chordal sevenths. However, we still hear the tendencies toward resolution as defining of chordal quality. Further, there are dissonances within chords that we do not necessarily want to sound, as you have pointed out. In those cases, we will keep the note that is more responsible for defining the chord quality (usually). So, in your examples:
Note that your assertion of two notes being insufficient to represent a chord is inaccurate. Two-voice baroque counterpoint has clear harmonic progression throughout. The same rules apply when the chords are simpler than those you list. For example, in a major or minor triad, the fifth is not necessary. In a dominant seventh sonority, the third and seventh are necessary (as the tendency tones), while the root and fifth can be omitted.
Of course, if you are playing in an ensemble, other instruments may have chord members that you do not, then, need to double. Finally, if you are performing with a soloist, it is best to avoid using the chord tones that the soloist is using. It will be nearly impossible to do so in an improvised solo setting, but if you are accompanying a known melody line, this principle can guide your voicing choices.
I am not a guitarist, but I hope this perspective generally has been helpful. As on all instruments, technical convenience (or necessity) may guide your choices quite often as well. Don't feel the need to include too many notes, though; sometimes doing so just makes the texture "muddy." Let your ears be your guide.
It depends. It always depends. But the bassist is playing the root and fifth, so I've heard that dropping them in favor of the third and seventh (and ninth, and six, or whatver) is something I've heard suggested.
This analysis of Freddie Green's style shows that he's hitting two notes, and one is muted to be mostly there, but that's in the Count Basie orchestra, where there's many horns and piano to provide the harmony, so the guitar's mostly rhythm.
If you keep the 11th and omit the 3rd, you'll get what is generally refered to as a "sus4" chord, the the 4th/11th tends to resolve to the third, which gives a standard V7 chord, resolving on I Maj7.
Limitations. For example, guitarists don't have the voicing freedom of pianists. When I simplify a chord with omissions, the unaltered fifth is the first to go, since it is implied in the overtones of the root. I typically retain the root, third, seventh, and the highest tension; any additional voices depends upon fretboard fingering.
From what I've learned, simply, you only need the 3rd, and all of the extensions above it in a jazz band. Someone in the band will be playing the root, so you don't necessarily have to play it, the 3rd gives the chord some flavor.. it tells if its a major, minor, etc. All of the extensions past the 5th of the chord define it further past what the bands doing, so you'll want to play those also.
As a general rule of composition, following the minimalist school, you want to fashion an accompaniment chord so that it contains the minimum number of notes needed to achieve the desired chord perception. A good way to test for minimality is to omit one note at a time...the result should be loss of definition of the chord.
Two common reasons why a chord-defining note can be omitted from the accompaniment chord are 1) the bass covers the root note, making it redundant and unnecessary in the accompaniment, and 2) the melody covers one of the chord-defining notes, making it redundant and not needed in the accompaniment. Example: A vocal jazz combo is striking a C 7 chord. The bass plays a low C root. The vocalist is singing a G (5th). The only two notes of the C7 chord needing to be struck on the accompaniment chord are E and Bflat (diminished 5th interval). Minimalistic arrangements have been favored going back to classical. Each performer has an essential role in such an ensemble, i.e., nobody is redundant.
