Arrangement using DIATONIC REHARMONIZATION


Arrangement using DIATONIC REHARMONIZATION


Did you understand the previous theory of ” DIATONIC REHARMONIZATION “?

This time I would like to explain the arrangement using diatonic reharmonication.

If you haven’t read the ” DIATONIC REHARMONIZATION ” article or if you don’t understand it, you can read it from the following article.

Diatonic Reharmonization

Let’s move on, you can change the atmosphere of the song by reharmonizing only the chord progression without changing the melody of those songs, such as songs that have been completed or songs of someone’s artist.

Let’s do it! Please listen to the sound source below first. (Caution for volume)

 

The sound source has a very simple sound movement for the sake of clarity.

The chord progression is made only by “G → D” (I → V) .

Key = G

G (I)            D (V)

| ——————- | ——————- | ——— ———- | ——————- |

G (I)            D (V)

| ——————- | ——————- | ——— ———- | ——————- |

The bass is also just playing the root note in eighth notes.

Let’s reharmonize this song diatonic.

First of all, I remember what I did last time.

The “I △ 7 ” tonic system can be replaced with “Ⅲ m7 ” and “VI m7 “.

The “IV △ 7 ” subdominant system can be replaced with “II m7 “.

The “V 7 ” dominant system can be replaced with “VII ф “.

For the time being, let’s write down the 3 chords as well.

The “I” tonic system can be replaced with “Ⅲ m ” and “VI m “.

The “IV” subdominant system can be replaced with “II m “.

The “V” dominant system can be replaced with “VII dim “.

Let’s actually replace it.

G (I)   D (V)

| ——————- | ——————- | ——— ———- | ——————- |

G (I)   D (V)

| ——————- | ——————- | ——— ———- | ——————- |

First, let’s change (I) of G. Possible are Bm “Ⅲ m ” and Em “VI m “. By the way, “VI m ” is a minor key, so it’s a bit normal from Em , so let’s replace it with Bm of III m .

Bm (Ⅲm)   D (V)

| ——————- | ——————- | ——— ———- | ——————- |

Bm (Ⅲm)   D (V)

| ——————- | ——————- | ——— ———- | ——————- |

Like this …

Next, I’d like to change (V) of D , but it’s okay to change the whole code, but I’d like to change it a little differently.

Since it is one chord in two measures, I will change the part of D (V) by adding F # dim of “VII dim “.

Bm (Ⅲm)   D (V)  F # dim (VIIdim)

| ——————- | ——————- | ——— ———- | ——————- |

Bm (Ⅲm)   D (V)  F # dim (VIIdim)

| ——————- | ——————- | ——— ———- | ——————- |

Like this …

The sound source changed in this way is as follows.(Caution for volume)

 

The style of playing hasn’t changed, the bass is just playing the root note in eighth notes.

Harmony has changed by reharmonizing the code.

But with this, I think it will be like “even if you say that you arranged it …”.

So next, let’s change the rhythm a little from here.

Music is made up of three elements: melody, harmony, and rhythm . Since the previous song was reharmonized, it means that the harmony of one of the three elements has been changed.

Since this song is an arrangement, I have to leave the melody as it is, so I will change the elements of the rhythm for the rest.

First, let’s change the rhythm in an easy-to-understand manner!

The drums of the original song are played in regular time, so let’s make this a half-time drum.(Caution for volume)

 

As some of you may know when you listen to the song, I changed the phrase of the drum of 1 bar to the length of 2 bars. As the word “half time” means, the tempo of the drum is halved.

This has changed the image a little!

Let’s change this drum a little more like R & B because we want to make a little more change! For the time being, I omitted the details and pasted the drum rhythm appropriately. (Caution for volume)

 

It’s like this.

Finally, let’s change the rhythm of the bass.

Currently, I’m chopping eighth notes, so let’s use chord tones to add movement to the bass.

This time, the explanation of “reharmonization” is the main, so the explanation of “bass” and “drums” is omitted.(Caution for volume)

 

What is it like?

I think the tune has changed a lot compared to the beginning.

Arrangement may seem difficult, but you can change the atmosphere of the song just by “reharmonizing” “diatonic”.

The reference sound source was a little messy, but I hope you can convey the atmosphere, so please forgive me … (sweat)

Well, today is around here …

good job for today!
