Tritone substitution to a major chord?



Asked by: Diana Wang

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 V7 with ♭II7 (which could also be called ♭V7/V, subV7, or V7/♭V).

What note is a tritone away from C?





(or F#)

Gb (or F#) is a tritone away from C and C is a tritone away from Gb. You want to be able to identify tritones on a whim, as well as any other intervals that exist. Go ahead and test yourself. Pick a note and define what the tritone interval is.

How do you find the chord tritone?

Lets say you have a Bb7 chord. To find it’s tritone substitution you’d simply count up 6 half steps from there. 6 half steps higher than Bb is the note E. So, E7 is the tritone substitution of Bb7.

Is there a tritone substitution for minor chords?

NO ! There’s a reason why the tritone sub works on a dominant chord. That is because the 3rd and 7th are the same (just inverted function). But in a minor chord these two chords are just not the same.

What is the tritone substitution of an E7 chord?





So, if we had a D7 chord in a progression, a Tritone Substitution would switch in a G#7 chord in its place, and a Bb7 could be switched to an E7. The same is true the other way – a G#7 could be swapped for a D7 chord, and an E7 could be switched to a Bb7.

How do you use tritone substitutions?

The tritone substitution can be performed by exchanging a dominant seventh chord for another dominant seven chord which is a tritone away from it. For example, in the key of C major one can use D♭7 instead of G7. (D♭ is a tritone away from G).

What is the tritone of C major?

TRITONE SUBSTITUTION EXPLAINED (Jazz Piano Lesson) ·

Is C to F sharp a tritone?

C to F# is a tritone, because the distance between each of the notes is a whole step (a half step is the shortest distance between two notes, such as C to C# – a whole step is two half steps).

What is the tritone in C minor?

Tritones in Scales
In a natural minor scale (also called the Aeolian mode), the tritone is between the 2nd and the 6th. What is this? In C Minor, this would be the diminished 5th, D – Ab. In the Dorian mode (a minor scale with a raised 6th), the tritone is between the 3rd and the 6th.



Is a tritone a sharp 4 or flat 5?

To be 100% exact to the name ‘tritone’, it would be #4.

Is there a note between B and C?

So A=440, A#=466.2, B=493.9 and C=523.3. There is no note between B & C. By dividing a pitch, by 1.05946309436, you get the next lower semitone. There is a B#, which is enharmonic to C.

Why are there only 5 black keys?

And in the mid 15th century we decided that if you could lower a note with a flat, you could also raise a note with a sharp, so we invented that. The piano wasn’t created until another 300 years later, so it’s always had the five black key arrangement.



Why isn’t there an E#?

Why Is There No B# and E# On Instruments? The simplest answer is because these instruments were designed keeping in mind the theories of Western music, where there isn’t much room for these notes. There are 12 notes in each octave which occupy different frequencies. These are evenly distributed.

Does F flat exist?

Fb is a white key on the piano. Another name for Fb is E, which has the same note pitch / sound, which means that the two note names are enharmonic to each other. It is called flat because it is 1 half-tone(s) / semitone(s) down from the white note after which is is named – note F.

Why is there no FB major?

The main reason that this key isn’t used frequently is because it is enharmonically equivalent to the key of B, which only has 5 sharps instead of 7 flats, and is therefore easier for many instruments to play.

Is there such thing as E Sharp?

E# is a white key on the piano. Another name for E# is F, which has the same note pitch / sound, which means that the two note names are enharmonic to each other. It is called sharp because it is 1 half-tone(s) / semitone(s) up from the white note after which is is named – note E. The next note up from E# is F# / Gb.
