According to Wikipedia, In music , a ditone is the interval of a major third. The size of a ditone varies according to the sizes of the two tones of which it is compounded.
I actually don't like big grammar... what are the application?
The di-tone on your left hand is usually coupled with a form of quartal chord on your right hand. I like to associate them in clumps for better understanding, because there are other ways to use the di-tone. Here are some general rules to using this di-tone:
1. The di-tone mimics the bass line:
What this means is that if your bass line is C, then your di-tone will usually be C and E.
2. The di-tone is usually coupled with a quartal chord in the right hand
C E - Bb D# G# (Quartal chord)
As a Passing Tone
Remember to think about the bass note. The bass note is exactly what it sounds like: It is the actual sound and movement of the bass guitar. So if you hear the bass guitar on a song go from C to D to E, then your di-tones will be C E, D Gb , and E Ab. Your right hand chord will be Bb quartal lead – C quartal lead – D quartal lead.
But be careful! Make sure that when you hear the bass that you use the bass notes that are acting as passing tones. So you have a responsibility to learn and interpret the song to see if it’s a foundation bass note, or a passing tone. So what you can do is move the di-tone / quartal lead combination in whole notes to get to your destination. So if your starting point is C and your destination point is F, then you can use the di-tone / quartal lead combination that goes from C to F, but on F you play the foundation chord.
N.B. The reason why I describe this as a di-tone / quartal lead combination, is because what you can do with the quartal chord is play around with the *quartal lead chords. I also call it a quartal lead because it is not the actual quartal chord that goes with the tone, but the leading chord that will take you there. Get it?
This is why I describe the chord in clumps, because each clump has its own distinct way of use, even though they are used in combination.
Replacing the 1 Chord
You hear this done in jazz music an awful lot. Instead of playing a regular C major chord, you can play:
LH - RH
C E - A D G (C Quartal chord)
You can even move these chord combinations in whole or half steps, up and down, to get to your destination, and it sounds really jazzy.
A quartal chord as a chord in fourth degrees, or a triad chord combination with intervals of four notes e.g. l – r – s. From the first note to the next note are four tones.
The di-tone is usually used to substitute for your diminished 3rd chord. Let’s say you have this progression:
t r fe / l de m - m d r / se d r s - l m s / s t d
You can substitute the 3rd diminished chord representation with your di-tone, or use your di-tone to play passing chords to your destination:
m se - r s d
m se / r s d = fe to / m l r = se d / fe t m
