The Difference Between sus, 7, And sus7 Chords (Example: Asus, A7, Asus7)

'sus' chord refers to the 4th note in the scale replacing the 3rd note. A 7th chord refers to a major triad with the 7th note on top:

A major = A C# E
Asus = A D E
A7 = A C# E G
Asus7 = A D E G

Or if you'd rather see it as intervals:
A = R 3 5
Asus = R 4 5
A7 = R 3 5 7
Asus7 = R 4 5 7

Sometimes the triad is a 'sus' chord, rather than a major and minor chord. As a result, seventh chords can have many different 'options' for sounds and intervals in the triad (as well as added extensions and tensions like 9ths, 11ths, augmented, and 13ths)

Can some please tell me what the diffrence between "A" and "A major"

[waltribeiro]

@Life4Summer nothing. they're both the same. SAying something is in the key of A is implied to mean "A Major"

[hanzimaster]

sus = 1/4/5

7=1/3/5/b7

sus7 = 1/5/b7

[waltribeiro]

@hanzimaster almost. sus7 has the 4th in it

[hanzimaster]

@waltribeiro i thought that was sus4and7 which doesn't exist

[waltribeiro]

@hanzimaster sus4add7 and 7sus4 are the same chord. bThe former is written incorrectly though. Unless you were referring to no fifth interval in the chord?

[none1889]

I didnt get it would you blease play it more explain

[timsmashuhoe]

Where do u ask this guy questions  I just want to know if you can play parallel over progressions I have no one to jam with so I can't hear but would it sound good to play for example augmented a raised fith over a major chord or vise versa or diminished over a major chord

[timsmashuhoe]

Sorry makes no sense my last post in the begging of the video you said that g is in the a major scale but it's not it's g#

[timsmashuhoe]

Good video but I had to point out that in the key of a there is 3 sharps and they are c# f# and g# . awbwc#hdwewf#wg#ha
