These notes are always labelled in this order — for example, if you have a D and you go up one note you always get an E maybe Eb or E , but the letter is always E , and down one note is always C. In the A — B example above on the right , A — B are next to each other on the scale, so we know that their interval is a 2nd. A tritone is a very specific interval — it is the interval made from six semitones, or three whole tones. In fact, in every Major scale, the 4th note and the 7th note will form a tritone, and specifically an augmented 4th.
In a natural minor scale also called the Aeolian mode , the tritone is between the 2nd and the 6th. In the Dorian mode a minor scale with a raised 6th , the tritone is between the 3rd and the 6th. In the Mixolydian scale a major scale with a lowered 7th degree , which creates a dominant chord, the tritone is found between the 3rd and the 7th. As you can see, any and all of the main diatonic scales you will see in music have exactly one tritone in them, though they are all in a different place.
The main use of a tritone in music is to create instability and tension, and then to resolve this tension by moving from a tritone to the next chord in the progression. This motion of tension and release gives a weight and a significance to the chord after the tritone, and it is often that this chord is the tonic chord of the piece of music:.
This is a very typical use of a tritone — the G7 chord G — B — D — F has a tritone formed by the B — F interval, and that interval resolves via contrary motion one goes up and the other goes down to the C and E of the C Maj chord.
The tritone actually played a vital role in the development of modern harmony Did you know that not all accidentals were created at the same time? F sharp and B flat were the first ones, and they were invented to try and solve the problem of the tritone in music.
In times past, music was organised into modes rather than keys. The modes only used the white keys on a keyboard, so the only way you could play a different scale, or a different pattern of tones and semitones, was to start on a different note. Each mode had its own recognisable flavour and character. There was an accepted tradition of which modes were suitable for joyful music e.
Ionian and Lydian and which were for more mournful subjects, e. Dorian and Phrygian. The system of modes worked for every note of the scale This went against everything music appeared to stand for, and was christened diabolus in musica — the Devil in music.
The Locrian mode was very rarely used. In earlier times, it was called "the devil in music", which thousands of people grasp on to when they hear that and decide they can make their music "dark" or "evil", etc.
Its also been exploited because its use was so restricted in the tonal era, and because of its symmetry it divides the octave in half etc. In Jazz, it is used heavily to imply dominant 7th chords, among other things. Maybe you should google "historical uses of the tritone" and see what you get. Best, Steve Reply Quote. It's basically notation for the Tritone Sub, which is very common. You can "substitute" one chord for the other because they share this common interval which is understood to be the driving force and "most important" notes of the chord.
You may also see "Polychords" or "Bichords. Michael Oguns. I have basic knowledge of tritones however I need to understand where and when to use the tritones and what tritones fit together to create that contemporary sound.
I also would like to know what the bass chords would be when using a tritone. Is it a case whereby you would have a C major chord on the right hand with a the root - C and the diminished 5th - Gb as the bass notes?
The most typical use of a tritone - especially in jazz - is to provide the 3rd and 7th of a Dominant 7th chord. Or, another way, every Dominant 7th chord has a tritone between it's 3rd and 7th. In many cases, players use just these two notes to imply the harmony they want a C7 chord in this case - and that assumes that the bass player is playing a C, etc. In fact, that's true of any teo dominant 7th chords whose roots are a 4th or 5th apart - you can move the tritone of one up or down a half step to get to the tritone that's the 3rd and 7th of the next chord and the 3rd of one becomes the 7th of the next, and vice versa, which is pretty cool.
Using a tritone from the root of the chord - such as an F or Gb over a C gives a "diminished" or "flat five" b5 sound. Both diminished and half-diminished 7th chords contain a b5 9and the diminished actually has two tritones in it! But, treating the 4 at a 11 has a very "Lydian" sound - which is fairly contemporary sounding in a lot of genres. Putting a C chord in the RH with a Gb in the Left as the bass is not as common, but it does have it's own sound.
Other chords also contain tritones in different places, but it seems the most "effective" place for them to be traditionally to really "define" a chord's sound is between 1 and 5, or 2 and 7. Putting them in other places tends to be more of a "coloration" of a chord. As another response mentions, the tritone was considered "the devil in music" way back in olden days. And because some people learn that, and want to make what they think is "dark" or "evil" music, etc.
In that context, it has taken on a "darker" connotation, but that's only one use of the interval - it appears in many.
My suggestion to you is to just experiment with the sound - try adding a tritone to existing chords, or play a tritone and add a note, or notes, to it, and see what kind of sounds you can get. Hi everyone! Can someone help me defining a Tritone? How are tritones used, do you substitude a chord with a tritone? A tritone is an interval, part of a chord. I think stevel's post - 2 years ago! Is there something you don't understand about his answer?
