Note #4 Chords Reference Video
1 note is a note
2 notes is an interval
Atleast 3 notes is a Chord
2 types of chords
- Major Chords - Happy
- Minor Chords - Melancholic
Add a single note, then add 7 notes on top of it, it's called fifth interval neutral
The interval with first note and last note called neutral that means it's not major Chord minor Chord, the middle note between these 2 notes will decide if the chord is major or minor
If you count 3 notes up and delete others, everytime you have a 2 note space between last note and middle note it is a minor Chord

If you move the middle note one half note up, it will convert the minor Chord into a major Chord, it's also the 3 half note gap between low note and middle note
This is a Em (E Minor Chord)
To change the vibe you can select the middle note and move it 1 octave high
