  • Common Jazz Chord Symbols Here I Use the More Explicit Abbreviation 'Maj7' for Major Seventh
    Common jazz chord symbols Here I use the more explicit abbreviation 'maj7' for major seventh. Other common abbreviations include: C² C²7 CMA7 and CM7. Here I use the abbreviation 'm7' for minor seventh. Other common abbreviations include: C- C-7 Cmi7 and Cmin7. The variations given for Major 6th, Major 7th, Dominant 7th, basic altered dominant and minor 7th chords in the first five systems are essentially interchangeable, in other words, the 'color tones' shown added to these chords (9 and 13 on major and dominant seventh chords, 9, 13 and 11 on minor seventh chords) are commonly added even when not included in a chord symbol. For example, a chord notated Cmaj7 is often played with an added 6th and/or 9th, etc. Note that the 11th is not one of the basic color tones added to major and dominant 7th chords. Only #11 is added to these chords, which implies a different scale (lydian rather than major on maj7, lydian dominant rather than the 'seventh scale' on dominant 7th chords.) Although color tones above the seventh are sometimes added to the m7b5 chord, this chord is shown here without color tones, as it is often played without them, especially when a more basic approach is being taken to the minor ii-V-I. Note that the abbreviations Cmaj9, Cmaj13, C9, C13, Cm9 and Cm13 imply that the seventh is included.

  • Naming a Chord Once You Know the Common Names of the Intervals, the Naming of Chords Is a Little Less Daunting
    Naming a Chord Once you know the common names of the intervals, the naming of chords is a little less daunting. Still, there are a few conventions and short-hand terms that many musicians use, that may be confusing at times. A few terms are used throughout the maze of chord names, and it is good to know what they refer to: Major / Minor – a “minor” note is one half step below the “major.” When naming intervals, all but the “perfect” intervals (1,4, 5, 8) are either major or minor. Generally if neither word is used, major is assumed, unless the situation is obvious. However, when used in naming extended chords, the word “minor” usually is reserved to indicate that the third of the triad is flatted. The word “major” is reserved to designate the major seventh interval as opposed to the minor or dominant seventh. It is assumed that the third is major, unless the word “minor” is said, right after the letter name of the chord. Similarly, in a seventh chord, the seventh interval is assumed to be a minor seventh (aka “dominant seventh), unless the word “major” comes right before the word “seventh.” Thus a common “C7” would mean a C major triad with a dominant seventh (CEGBb) While a “Cmaj7” (or CM7) would mean a C major triad with the major seventh interval added (CEGB), And a “Cmin7” (or Cm7) would mean a C minor triad with a dominant seventh interval added (CEbGBb) The dissonant “Cm(M7)” – “C minor major seventh” is fairly uncommon outside of modern jazz: it would mean a C minor triad with the major seventh interval added (CEbGB) Suspended – To suspend a note would mean to raise it up a half step.

  • Ninth, Eleventh and Thirteenth Chords Ninth, Eleventh and Thirteen Chords Sometimes Referred to As Chords with 'Extensions', I.E
    Ninth, Eleventh and Thirteenth chords Ninth, Eleventh and Thirteen chords sometimes referred to as chords with 'extensions', i.e. extending the seventh chord to include tones that are stacking the interval of a third above the basic chord tones. These chords with upper extensions occur mostly on the V chord. The ninth chord is sometimes viewed as superimposing the vii7 chord on top of the V7 chord. The combination of the two chord creates a ninth chord. In major keys the ninth of the dominant ninth chord is a whole step above the root (plus octaves) w w w w w & c w w w C major: V7 vii7 V9 G7 Bm7b5 G9 ? c ∑ ∑ ∑ In the minor keys the ninth of the dominant ninth chord is a half step above the root (plus octaves). In chord symbols it is referred to as a b9, i.e. E7b9. The 'flat' terminology is use to indicate that the ninth is lowered compared to the major key version of the dominant ninth chord. Note that in many keys, the ninth is not literally a flatted note but might be a natural. 4 w w w & #w #w #w A minor: V7 vii7 V9 E7 G#dim7 E7b9 ? ∑ ∑ ∑ The dominant ninth usually resolves to I and the ninth often resolves down in parallel motion with the seventh of the chord. 7 ˙ ˙ ˙ ˙ & ˙ ˙ #˙ ˙ C major: V9 I A minor: V9 i G9 C E7b9 Am ˙ ˙ ˙ ˙ ˙ ? ˙ ˙ The dominant ninth chord is often used in a II-V-I chord progression where the II chord˙ and the I chord are both seventh chords and the V chord is a incomplete ninth with the fifth omitted.

  • Boris's Bells, by Way of Schubert and Others
    Boris's Bells, By Way of Schubert and Others Mark DeVoto We define "bell chords" as different dominant-seventh chords whose roots are separated by multiples of interval 3, the minor third. The sobriquet derives from the most famous such pair of harmonies, the alternating D7 and AI? that constitute the entire harmonic substance of the first thirty-eight measures of scene 2 of the Prologue in Musorgsky's opera Boris Godunov (1874) (example O. Example 1: Paradigm of the Boris Godunov bell succession: AJ,7-D7. A~7 D7 '~~&gl n'IO D>: y 7 G: y7 The Boris bell chords are an early milestone in the history of nonfunctional harmony; yet the two harmonies, considered individually, are ofcourse abso­ lutely functional in classical contexts. This essay traces some ofthe historical antecedents of the bell chords as well as their developing descendants. Dominant Harmony The dominant-seventh chord is rightly recognized as the most unambiguous of the essential tonal resources in classical harmonic progression, and the V7-1 progression is the strongest means of moving harmony forward in immediate musical time. To put it another way, the expectation of tonic harmony to follow a dominant-seventh sonority is a principal component of forehearing; we assume, in our ordinary and long-tested experience oftonal music, that the tonic function will follow the dominant-seventh function and be fortified by it. So familiar is this everyday phenomenon that it hardly needs to be stated; we need mention it here only to assert the contrary case, namely, that the dominant-seventh function followed by something else introduces the element of the unexpected.

  • Seventh Chord Progressions in Major Keys
    Seventh Chord Progressions In Major Keys In this lesson I am going to focus on all of the 7th chord types that are found in Major Keys. I am assuming that you have already gone through the previous lessons on creating chord progressions with basic triads in Major and Minor keys so I won't be going into all of the theory behind it like I did in those lessons. If you haven't read through those lessons AND you don't already have that knowledge under your belt, I suggest you download the FREE lesson PDF on Creating and Writing Major Key Chord Progressions at www.GuitarLessons365.com. So What Makes A Seventh Chord Different From A Triad? A Seventh Chord IS basically a triad with one more note added. If you remember how we can get the notes of a Major Triad by just figuring out the 1st, 3rd and 5th tones of a major scale then understanding that a Major Seventh Chord is a four note chord shouldn't be to hard to grasp. All we need to do is continue the process of skipping thirds to get our chord tones. So a Seventh Chord would be spelled 1st, 3rd, 5th and 7th. The added 7th scale degree is what gives it it's name. That is all it is. :) So what I have done for this theory lesson is just continue what we did with the basic triads, but this time made everything a Seventh Chord. This should just be a simple process of just memorizing each chord type to it's respective scale degree.

  • The Strategic Half-Diminished Seventh Chord and the Emblematic Tristan Chord: a Survey from Beethoven to Berg
    International Journal ofMusicology 4 . 1995 139 Mark DeVoto (Medford, Massachusetts) The Strategic Half-diminished Seventh Chord and The Emblematic Tristan Chord: A Survey from Beethoven to Berg Zusammenfassung: Der strategische halbverminderte Septakkord und der em­ blematische Tristan-Akkord von Beethoven bis Berg im Oberblick. Der halb­ verminderte Septakkord tauchte im 19. Jahrhundert als bedeutende eigen­ standige Hannonie und als Angelpunkt bei der chromatischen Modulation auf, bekam aber eine besondere symbolische Bedeutung durch seine Verwendung als Motiv in Wagners Tristan und Isolde. Seit der Premiere der Oper im Jahre 1865 lafit sich fast 100 Jahre lang die besondere Entfaltung des sogenannten Tristan-Akkords in dramatischen Werken veifolgen, die ihn als Emblem fUr Liebe und Tod verwenden. In Alban Bergs Lyrischer Suite und Lulu erreicht der Tristan-Akkord vielleicht seine hOchste emblematische Ausdruckskraft nach Wagner. If Wagner's Tristan und Isolde in general, and its Prelude in particular, have stood for more than a century as the defining work that liberated tonal chro­ maticism from its diatonic foundations of the century before it, then there is a particular focus within the entire chromatic conception that is so well known that it even has a name: the Tristan chord. This is the chord that occurs on the downbeat of the second measure of the opera. Considered enharmonically, tills chord is of course a familiar structure, described in many textbooks as a half­ diminished seventh chord. It is so called because it can be partitioned into a diminished triad and a minor triad; our example shows it in comparison with a minor seventh chord and an ordinary diminished seventh chord.

  • Fully-Diminished Seventh Chords Introduction
    Lesson PPP: Fully-Diminished Seventh Chords Introduction: In Lesson 6 we looked at the diminished leading-tone triad: vii o. There, we discussed why the tritone between the root and fifth of the chord requires special attention. The chord usually appears in first inversion precisely to avoid that dissonant interval sounding against the bass when vii o is in root position. Example 1: As Example 1 demonstrates, placing the chord in first inversion ensures that the upper voices are consonant with the bass. The diminished fifth is between the alto and soprano, concealed within the upper voices. In this case, it is best understood as a resultant interval formed as a result of avoiding dissonances involving the bass. Adding a diatonic seventh to a diminished leading-tone triad in minor will result in the following sonority: Example 2: becomes This chord consists of a diminished triad with a diminished seventh added above the root. It is therefore referred to as a fully-diminished seventh chord. In this lesson, we will discuss the construction of fully-diminished seventh chords in major and minor keys. As you will see, the chord consists of two interlocking tritones, which require particularly careful treatment because of their strong voice-leading tendencies. We will consider its various common functions and will touch on several advanced uses of the chord as well. Construction: Fully-diminished leading-tone seventh chords can be built in major or minor keys. In Roman numeral analyses, they are indicated with a degree sign followed by seventh-chord figured bass numerals, o7 o 6 o 4 o 4 depending on inversion ( , 5 , 3 , or 2 ).

  • The Consecutive-Semitone Constraint on Scalar Structure: a Link Between Impressionism and Jazz1
    The Consecutive-Semitone Constraint on Scalar Structure: A Link Between Impressionism and Jazz1 Dmitri Tymoczko The diatonic scale, considered as a subset of the twelve chromatic pitch classes, possesses some remarkable mathematical properties. It is, for example, a "deep scale," containing each of the six diatonic intervals a unique number of times; it represents a "maximally even" division of the octave into seven nearly-equal parts; it is capable of participating in a "maximally smooth" cycle of transpositions that differ only by the shift of a single pitch by a single semitone; and it has "Myhill's property," in the sense that every distinct two-note diatonic interval (e.g., a third) comes in exactly two distinct chromatic varieties (e.g., major and minor). Many theorists have used these properties to describe and even explain the role of the diatonic scale in traditional tonal music.2 Tonal music, however, is not exclusively diatonic, and the two nondiatonic minor scales possess none of the properties mentioned above. Thus, to the extent that we emphasize the mathematical uniqueness of the diatonic scale, we must downplay the musical significance of the other scales, for example by treating the melodic and harmonic minor scales merely as modifications of the natural minor. The difficulty is compounded when we consider the music of the late-nineteenth and twentieth centuries, in which composers expanded their musical vocabularies to include new scales (for instance, the whole-tone and the octatonic) which again shared few of the diatonic scale's interesting characteristics. This suggests that many of the features *I would like to thank David Lewin, John Thow, and Robert Wason for their assistance in preparing this article.
