We will introduce the BS method (Big/Small method), which is said to be the easiest way to distinguish between major and minor chords.
*Major chord: bright chord
*Minor chord: dark chord
See the interval between chord notes
First, count the distance between the three notes of the "tonic chord," which is a triad created with the tonic of the scale as the root note.
The size of the interval at that time is
“Big/Small” is a major chord
“Small/Big” means a minor chord.
It becomes.
I think many people don't know what I'm talking about.
It sounds complicated, but it's easy if you look at the example below.
*First, let's take a major chord as an example.
The major chord "F" starts from the root note and sounds like "F, A, C," or "F, A, C."
Between the sounds of "F" and "A", there are three sounds: "F♯", "G", and "G♯".
On the other hand, there are only two sounds between "A" and "C": "A♯" and "C".
Since there is a "two" after the "three", it is "Big/Small", so it is a major chord.
*Let's look at minor chords in the same way.
The minor chord "Fm" starts from the root note and is "F, G♯, C", or "F, G#, C".
Between the sounds of "F" and "G♯" there are two, "F♯" and "G".
On the other hand, there are three sounds between "G♯" and "C": "A", "A♯", and "C".
It is a minor chord because there is a ``three'' after the ``two'', so it is ``Small/Big''.
These "three" and "two" are fixed numbers common to all major and minor chords.
Once you've decided on a random root note, try creating a chord using the sense of ``3'' and ``2''.
I'm sure it will match the correct major chord.
Similarly, if you leave an interval of ``2'' or ``3'', it should match the minor chord.
The root note can be a black key as well as a white key.
Even in J-POP music that you often listen to, when the tune changes, such as before the chorus, major or minor chords with the black key as the root note are often used.
Instead of memorizing major and minor chords by rote, let's memorize the rules of ``3'' and ``2'' and try playing various chords on your own.
Composing'' various chords is a shortcut to memorizing chords.
