C, it will be “tritone sub” –> C . In Blues and Jazz turnarounds, it's common practice to use harmonic substitutions for any of the chords. "A Royal Scam: The Abstruse and Ironic Bop-Rock Harmony of Steely Dan", Satyendra, Ramon. Now I understand and I just have to start practising, Your email address will not be published. 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 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 tritone substitution can be performed by exchanging a dominant seven chord for another dominant seven chord which is a tritone away from it. It is the center-point of an octave (splits an octave in two equal halves). my brain is busting right now but glad you took the time to explain it. 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. In this case, however, we're … Next, here is the same 12 bars, except incorporating a tritone substitution in bar 4; that is, with G♭7 substituted for C7. Here’s how it works. Tritone-substitution. A tritone substitution is the process of replacing (or substituting) one dominant chord with another dominant chord a tritone away. 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 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. 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. Notice that the interval between the third and seventh of a dominant seventh chord is itself a tritone. 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#. Because they share the same tritone, they are possible substitutes for one another. This site uses Akismet to reduce spam. One of the most common tritone subs is Tritone Sub of V. "[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]. 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. Years ago you could get banned from the church for even playing a tritone due to its very “harsh” or dissonant sound. Also in jazz harmony, the tritone is both part of the dominant chord and its substitute dominant (also known as the sub V chord). It often functions as a substitute for the V7 chord in a ii-V7-I progression.

In standard jazz harmony, tritone substitution works because the two chords share two pitches: namely, the third and seventh, albeit reversed. 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]. This substitution is particularly suitable for jazz because it produces chromatic root movement. A tritone substitution occurs whenever a chord is being substituted or replaced by another chord with a root a tritone interval away. In tonal music, a conventional perfect cadence consists of a dominant seventh chord followed by a tonic chord. G7 = G B D F 2. 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. What is a tritone substitution? 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). For example, in the key of C major one can use D♭7 instead of G7. Thus, the alt chord is equivalent to the tritone substitution with a sharp–eleventh alteration. The tritone substitution is one of the most common chord and improvisation devices in jazz. The answer is because dominant chords that are a tritone apart share the same 3rd and 7th. 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. Jerry Coker explains: Tritone substitutions and altered dominants are nearly identical... Good improvisers will liberally sprinkle their solos with both devices.

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. Tritone Substitution: The use of a chord three whole steps away to replace (or follow) the original chord. This is known as a tritone substitution. 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..? Had B been given the last word, or were the extreme registers reversed, the ploy would not have worked. You can also think of it as a b5 or a #4 away from any given note. In practice, a tritone sub in jazz is most commonly a dominant 7 chord. [9] (However, sharp elevenths also occur on non-substituted dominant chords in jazz.) Save my name, email, and website in this browser for the next time I comment. It sounds pretty sweet. 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. 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♭. 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. 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. 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]. 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. The substitute dominant may be used as a pivot chord in modulation. 2 Simple Ways to Find the Tritone Sub for any Key. The tritone substitution is one of the more useful harmonic progressions in jazz. A tritone is an interval of three whole tones between two notes. 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. Resolution to the original tonic is also common. This video looks at: What is a tritone? So, C to F# is a tritone. In this example I am substituting a Db7 for the G7 and creating a top-note melody that helps move the progression along. However, in 31 equal temperament and other systems that distinguish between 7:5 and 10:7, tritone substitution becomes more complex. 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. In the case of D♭7 to Cmaj7, the implied scale behind D♭7 would be D♭, E♭, F, G, A♭, B♭, C♭. The Tritone substitution is a very powerful way to add some extra tension and color to a II V I cadence. 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. So instead of G7 –> C, it will be “tritone sub” –> C . In Blues and Jazz turnarounds, it's common practice to use harmonic substitutions for any of the chords.

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 tritone substitution can be performed by exchanging a dominant seven chord for another dominant seven chord which is a tritone away from it. It is the center-point of an octave (splits an octave in two equal halves). my brain is busting right now but glad you took the time to explain it. 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. In this case, however, we're … Next, here is the same 12 bars, except incorporating a tritone substitution in bar 4; that is, with G♭7 substituted for C7. Here’s how it works. Tritone-substitution. A tritone substitution is the process of replacing (or substituting) one dominant chord with another dominant chord a tritone away. 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 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. 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. Notice that the interval between the third and seventh of a dominant seventh chord is itself a tritone. For example, the 5th tone of C Major is G.
