For example, in the progression Dm7–G7–CM7, substituting D♭7 for G7 produces the downward movement of D–D♭–C in the roots of the chords, typically played by the bass. Before you look at how trigonometric substitution works, here are some mnemonic tricks to help you keep this method straight. The jazz world has been using the tritone substitution for decades. The rules behind “tritone substitution” say that you can replace this G dominant7 with the dominant chord that is 3 whole steps away (or a “tritone” away). Next, here is the same 12 bars, except incorporating a tritone substitution in bar 4; that is, with G♭7 substituted for C7. [9] (However, sharp elevenths also occur on non-substituted dominant chords in jazz.) Also in jazz harmony, the tritone is both part of the dominant chord and its substitute dominant (also known as the sub V chord). What is a dominant 7th chord? There are even musicians (often times piano players) who have taken a liking to the world of reharmonizing and autom… thanks Will. Remember, with mnemonic devices, silly (and vulgar) works. Here, according to Richard Taruskin, “Strauss contrived an ending that seemed to die away on an oscillation between tonics on B and C, with C … getting the last word. A tritone substitution is the substitution of a dominant seventh chord with another chord whose root is a tritone (augmented fourth) lower. The tritone substitution primarily implies a Lydian dominant scale. Thus, the alt chord is equivalent to the tritone substitution with a sharp–eleventh alteration. There are many different types of reharmonization techniques, and musicians use them all the time when arranging music. This is the basic idea for substitution chords: keep certain elements of the original, perhaps elements that are distinctive to that chord (like the 1-3 interval for the first example or the tritone in the second), and see what other chords have that retained element. A tritone substitution is the substitution of one dominant seventh chord (possibly altered or extended) with another that is three whole steps (a tritone) from the original chord. my brain is busting right now but glad you took the time to explain it. All material © Jazzedge unless where noted. The tritone concept is also very useful for comping and improvised solos. Here in Part 2 of our discussion on tritone substitution we will go through some specific examples of how tritone substitution works in practice and discuss some ideas for improvisation. This video looks at: What is a tritone? You consent to our use of cookies if you continue to use this website. They work because the Guide Tones(3rd & 7th) are the same in both chords. The Tritone The tritone is an interval. This idea … The tritone (b5) substitution: bII A more conspicuous chord substitution is … Tritone substitution is a common chord substitution for dominant chords and occurs often in jazz standards. The tritone substitution is a dominant, or secondary dominant 7th chord whose root is a tritone (3 whole steps) away from the original chord. One of the most common Chord Substitutions in Jazz is the Tritone Substitution. A tritone is an interval made up of three tones, or six semitones. A tritone is the distance between the root and the #4. The answer is because dominant chords that are a tritone apart share the same 3rd and 7th. These chords are interchangeable because the tritone interval pitches are identical in each. This doesn’t mean you can’t substitute other chord qualities, but a dominant 7 is most often the chord being used to replace. This substitution is particularly suitable for jazz because it produces chromatic root movement. It would have been obvious that the C (though placed many octaves lower than its rival, in a register the ear is used to associating with the fundamental bass) was, in functional terms, making a descent to the tonic B as part of a “French sixth” chord… Rather than an ending in two keys, we are dealing with a registrally distorted, interrupted, yet functionally viable cadence on B.”[5]. Regarding your questions, I talk about tritone substitutions in Fretboard Theory Volume II Chapter 5, specifically page 87 under the heading “Diminished Chords As V7 Substitutions.” As far as subbing chords in the major scale, any major chord can be subbed for its relative minor and vice versa. Shown below is one of the simpler forms of twelve-bar blues. Save my name, email, and website in this browser for the next time I comment. Tritone Substitution: The use of a chord three whole steps away to replace (or follow) the original chord. It cleared my mind. Their initial letters, t, s, and s, are the same letters as the initial letters of the name of this technique, t rigonometric s ubstitution. This is also the case in 22 equal temperament and tritone substitution works similarly there. The augmented sixth chord can either be the Italian sixth It+6, which is enharmonically equivalent to a dominant seventh chord without the fifth; the German sixth Gr+6, which is enharmonically equivalent to a dominant seventh chord with the fifth; or the French sixth Fr+6, which is enharmonically equivalent to the Lydian dominant without the fifth but with a sharp eleven, all of which serve in a classical context as a substitute for the secondary dominant of V.[12][13]. In Part 1 of our article on tritone substitutions we discussed the tritone interval, the tritone substitution, and the theory behind why tritone substitution works. "[6] Patricia Julien says it involves replacing "harmonic root movement of a fifth with stepwise root movements (e.g., G7–C becomes D♭7–C) so that although stepwise root movement is involved, the relationship between the chords is functional".[8]. Because of this, the extensions of 9, ♯11 and 13 are all available, while the ♯11 is where it shares with the altered scale. A tritone substitution is the substitution of one dominant seventh chord (possibly altered or extended) with another that is three whole steps (a tritone) from the original chord.In other words, tritone substitution involves replacing V 7 with ♭ II 7 (which could also be called ♭ V 7 /V, subV 7, or V 7 / ♭ V).For example, D ♭ 7 is the tritone substitution for G 7. A dominant chord wants to resolve to the I chord. Taking the tri-tone idea a step further is to substitute the G7 with a complete II V, so in this case an Abm7 Db7. G7 = G B D F 2. 1. A tritone is an interval of an augmented 4th (or a diminished 5th; the distance between the two notes is six half-steps or three whole-steps). For example, the 5th tone of C Major is G. Now we simply go down one 1/2 step (or semitone) from G, and we end up on F#. Tritone substitutions are sometimes used in improvisation—often to create tension during a solo. An interval is a distance between two points. Tritone-substitution. 2 Simple Ways to Find the Tritone Sub for any Key. (Tritone Substitution, bVI Turnarounds, Coltrane Changes, etc) • Rhythmic Forward Motion: Playing into "one" • Melodic Forward Motion: Lines that anticipate the chord change • … Audubon Birders Engagement Calendar 2018 sailing for dummies jj isler, scales approach tritone substitution … You can also think of it as a b5 or a #4 away from any given note. Here’s how it works. You might ask how is this possible? In practice, a tritone sub in jazz is most commonly a dominant 7 chord. [10] Since it is the dominant chord a tritone away, the substitute dominant may resolve down a fifth, to a tonic chord a tritone away from the previous tonic (for example, in F one may feature a ii–V on C, which with a substitute dominant resolves to G♭, a distant key from F). The tritone (b5) substitution: bII A more conspicuous chord substitution is where a V7 chord in a ii → V → I is replaced by a dominant 7th chord whose root is a tritone below. Now I understand and I just have to start practising, Your email address will not be published. A simple comparison of the notes generally used with the given chord [notation] and the notes used in tri-tone substitution or altered dominants will reveal a rather stunning contrast, and could cause the unknowledgeable analyzer to suspect errors. A tritone is an interval of three whole tones between two notes. Edward Sarath calls tritone substitutions a "non-diatonic practice that is indirectly related to applied chord functions... yield[ing] an alternative melodic pathway in the bass to the tonic triad. In standard jazz harmony, tritone substitution works because the two chords share two pitches: namely, the third and seventh, albeit reversed. ... Dummies Guide to Jazz Standards How to Learn Jazz Standards Autumn Leaves All the Things You Are Summertime Misty Moon River Blue in Green Giant Steps My Funny Valentine I Fall in Love Too Easily The tritone substitution is a chord substitution usable whenever a song contains V7 to I movement in the chords, for example G7 to C, Eb7 to Ab, or C7 to F. It's as simple as substituting a dominant 7th chord a tritone away from the V7 chord in your original key. Enharmonically, this is almost the same as the scale for G♭7, which is the tritone substitute of C7: G♭, A♭, B♭, C♭, D♭, E♭, F♭. So, C to F# is a tritone. The tri-tone of any note is that note which is 3 full tones away from the starting or original note. The only difference is C, which is the sharp eleventh of the G♭7 chord. In tonal music, a conventional perfect cadence consists of a dominant seventh chord followed by a tonic chord. For example, in the key of C major, the chord of G7 is followed by a chord of C. In order to execute a tritone substitution, common variant of this progression, one would replace the dominant seventh chord with a dominant chord that has its root a tritone away from the original: Franz Schubert’s String Quintet in C major concludes with a dramatic final cadence that uses the third of the above progressions. This is known as a tritone substitution. The tritone substitute dominant often contains the original dominant pitch (the sharp fourth, also called sharp eleventh or flat fifth, relative to the original root) due to its importance melodically and tonally, and this is one of the ways in which substitute dominants may sound and function somewhat differently than conventional dominant chords. For example, if … A tritone substitution occurs whenever a chord is being substituted or replaced by another chord with a root a tritone interval away. Since the topic can be kind of confusing, Im gonna try to explain it in a way that normal people can understand.... - What is a tri-tone..?

This site uses Akismet to reduce spam. Though examples of the tritone substitution, known in the classical world as an augmented sixth chord, can be found extensively in classical music since the Renaissance period,[1] they were not heard until much later in jazz by musicians such as Dizzy Gillespie and Charlie Parker in the 1940s,[2] as well as Duke Ellington, Art Tatum, Coleman Hawkins, Roy Eldridge and Benny Goodman.[3]. Had B been given the last word, or were the extreme registers reversed, the ploy would not have worked. That F# is our Tritone, or we also call that a diminished 5th. In this case, however, we're … "A Royal Scam: The Abstruse and Ironic Bop-Rock Harmony of Steely Dan", Satyendra, Ramon. In this example I am substituting a Db7 for the G7 and creating a top-note melody that helps move the progression along. Notice that the interval between the third and seventh of a dominant seventh chord is itself a tritone. If you’re still wondering how we got Db as an augmented fourth interval below G, then you need to subscribe to our early bird list to know when we’re releasing our latest comprehensive workbook on … The tritone substitution is one of the most common chord substitutions found in jazz and was the precursor to more complex substitution patterns like Coltrane changes. Podcast #43 - Turnarounds, I-VI-II-V and Tadd Dameron Chords. So if you see Ab7 and want to play a tritone sub, play Am7 D7.

But below it, the author (Eric Roche) Says "The IV7 chord (F7) is in fact a substitute for the B7 chord and could resolve to the Eminor (iii) chord also. "Analyzing the Unity within Contrast: Chick Corea's. The Tritone substitution is a very powerful way to add some extra tension and color to a II V I cadence. The tritone substitution is one of the more useful harmonic progressions in jazz. Most bassists are familiar with basic chord types, since we use basic R-3-5-7 chord tones for building bass lines all the time. However, in 31 equal temperament and other systems that distinguish between 7:5 and 10:7, tritone substitution becomes more complex. A tritone substitution is a great way to make a typical I-ii7-V sound more interesting. The tritone substitution can be performed by exchanging a dominant seven chord for another dominant seven chord which is a tritone away from it. Everett, Walter (Autumn, 2004). You may also be aware that different chords can sometimes be substituted for each other. This also reinforces the downward movement of the thirds and sevenths of the chords in the progression (in this case, F/C to F/C♭ to E/B). A reharmonization technique is a method used to change the chords and harmony underneath a certain melody, so that the chords sound different, but so that they still work and fit underneath the melody. The conventional G7 chord is replaced in bars 3 and 4 of the following example with a D♭7 chord, with a diminished fifth (G♮ as the enharmonic equivalent of A); a chord otherwise known as a ‘French sixth’: Christopher Gibbs (2000, p. 105) says of this ending: “within the last movement of the quintet, darker forces continue to lurk: the piece ends with a manic coda building to a dissonant fortissimo chord with a D-flat trill in both cellos, and then a final tonic inflected by a D-flat appoggiatura… The effect is overwhelmingly powerful.”[4], There are similarities here with the ambivalent ending of Richard Strauss’s tone poem Also Sprach Zarathustra. Classical harmonic theory would notate the substitution as an augmented sixth chord on ♭II (the augmented sixth being enharmonic to the dominant/minor seventh). Below is the original dominant-tonic progression, the same progression with the tritone substitution, and the same progression with the substitution notated as an Italian augmented sixth chord: One of the most common usages of the tritone substitution is in the 12-bar blues. The harmonic seventh chord (approximating 4:5:6:7) contains a small tritone, so its substitution must contain a large tritone and therefore will be a different (and more dissonant) chord type.[15]. For example, in the key of C major one can use D♭7 instead of G7. In Blues and Jazz turnarounds, it's common practice to use harmonic substitutions for any of the chords. Resolution to the original tonic is also common. Required fields are marked *. Tritone substitution is when a dominant 7 chord is substituted for the dominant 7th chord a tritone away. The tritone substition adds alot of harmonic interest and it sounds very smooth because the roots of the chords are moving by only a half step. In the case of D♭7 to Cmaj7, the implied scale behind D♭7 would be D♭, E♭, F, G, A♭, B♭, C♭. It often functions as a substitute for the V7 chord in a ii-V7-I progression. This type of substitution is known as a tritone substitution." And my own trick for substituting them on the fly: replace the dominant 7 chord by a II-V starting 1 semitone up. One of the most common tritone subs is Tritone Sub of V. Here in Part 2 of our discussion on tritone substitution we will go through some specific examples of how tritone substitution works in practice and discuss some ideas for improvisation. #5 Tritone II V Progression. Jerry Coker explains: Tritone substitutions and altered dominants are nearly identical... Good improvisers will liberally sprinkle their solos with both devices. The substitute dominant may be used as a pivot chord in modulation. A Tritone is the 5th tone of a scale minus one 1/2 step. We measure distance on the piano in intervals. So instead of G7 –> C, it will be “tritone sub” –> C . In other words, tritone substitution involves replacing V7 with ♭II7[6] (which could also be called ♭V7/V, subV7,[6] or V7/♭V[6]). Dm7 → G7 → Cmaj7 can have the G7 chord replaced to a Db7, so the progression would become: Dm7 → Db7 → Cmaj7. The second common usage of the tritone substitution is in ii–V–I progression, which is extremely common in jazz harmony. Attention: Intervals are the building block of chords. For example, C7alt is built from the scale C, D♭, E♭, F♭, G♭, A♭, B♭. The alt chord is a heavily altered dominant seventh chord, built on the alt scale, a scale where every scale degree except the root is flattened compared to the major scale. First, this involves three trig functions, tangent, sine, and secant. Example: G7 is replaced by Db7. This website uses cookies to personalize content and to analyze our traffic. The tritone substitution is one of the most common chord and improvisation devices in jazz. In this lesson, you’ll be looking at a simple way to think about the tritone substitution, as well as explore a few examples of how you can apply this cool concept to your jazz guitar comping and solos. What is a tritone substitution? The goal with tritone substitution is to replace this dominant chord with something that functions in a similar manner. [7] In a G7 chord, the third is B and the seventh is F; whereas, in its tritone substitution, D♭7, the third is F and the seventh is C♭ (enharmonically B♮). In Part 1 of our article on tritone substitutions we discussed the tritone interval, the tritone substitution, and the theory behind why tritone substitution works. Scott DeVeaux (Autumn, 1999). In each diatonic scale there is only one tritone, and it occurs between the fourth and seventh degrees of the scale, so in a C major scale this would be between F and B. A tritone substitution really is a reharmonization technique. (D♭ is a tritone away from G). Tritone substitutions are also closely related to the altered chord used commonly in jazz. Your email address will not be published. So a G7 would become a D♭7 (the root note is a tritone away). Example: G7 is replaced by Db7. The fact that a chord and its tritone substitution have the third and seventh in common is related to the fact that in 12 equal temperament, the 7:5 and 10:7 ratios are represented by the same interval, which is exactly half of an octave (600 cents) and is its own inversion. Years ago you could get banned from the church for even playing a tritone due to its very “harsh” or dissonant sound. Learn how your comment data is processed. D♭7 = D♭ F A♭ B Because they share the same tritone, they are possible substitutes for one another. How are tritones used to substitute dominant chords in chord progressions?
