How to remember the interval_1


How to remember the interval_1


I would like to explain how to remember the interval.

The interval is the note and the width of the note,

Depending on how many half tone “1/2 step” are between the notes and the width of the notes

Is it major ( M ) or minor (m) ?

Or it is determined whether it is an augment (aug) or a diminished (dim) .

Let’s explain the case from “do” to “mi” concretely.

First, calculate how many notes are raised from the reference note (lower note) to the upper note.

Counting “do” as 1 , up to “mi”, it goes up by 3 as do(1 ) → re ( 2 ) → mi (3)”.

The width of the interval will be 3rd .

Next, if there is no half tone “1/2 step” from the reference note (lower note) to the upper note, it is major.

If one half tone “1/2 step” is included, it becomes a minor.

If you calculate the interval from “do” to “mi”,

From “do” to “re” is whole tone,

Since “re” to “mi” are alsowholetone, they become major and become major.

The interval is major 3rd ( M3rd ) .

If it is “♭” me

From “do” to “re” is whole tone, from “re” to “♭” me is a half tone “1/2 step”. Since one half tone is entered, it becomes a minor, and the interval is a minor 3rd (m3rd ) .

The 2nd interval from “do” to “re” is the same idea , so I will omit it .

Next, I’d like to skip the 4th and 5th , and explain the 6th and 7th .

Now, let’s explain the case from “do” to “shi” concretely.

First, calculate how many notes are raised from the reference note (lower note) to the upper note.

“do”Counting as 1 and up to “shi”( 1 ) re( 2 ) mi( 3 ) fa( 4 ) sol( 5 ) la( 6 ) tiThe interval width is 7 because it goes up by 7 to ( 7 ) .It becomes th .

Next, if there is one half tone “1/2 step” from the reference note (lower note) to the upper note, it is major.

If two half tone “1/2 step” are included, it becomes a minor.

By the way, if three half tone “1/2 step” are included, it will be a diminished .

If you calculate the interval from “do” to “ti”,

From “do” to “re” is whole tone,

From “re” to “mi” is also whole tone,

From “mi” to “fa” is a half tone “1/2 step”, one came in here,

“fa” to “sol” is whole tone,

“sol” to “la” are also whole tone,

From “la” to “ti” is also whole tone,

From “do” to “ti”, there was only one half tone “1/2 step” from “mi” to “fa”, so it became a major scale .

The interval is Major 7th (M7th) .

If it is “♭, te”

Since “mi” to “fa” and “la” to “♭, tei” are half tone”1/2 step” ,

I thought that two half tone “1/2 step” would come in and became a minor .

The interval will be minor 7th .

The 6th interval from “do” to “la” is also an idea , so I will omit it .

And remember another pattern,

In the case of 7th , if the sound of “ti” is “♭♭, ta”,

Considering that there is another half tone “1/2 step” from the minor and there are three half tone “1/2 step” ,

The interval is the diminished 7th .

It’s a bit of an application, so don’t get confused and remember it.

Next time, I would like to explain the concept of 4th and 5th .
