If on a keyboard I played an A minor chord with my right hand with a 6th (F) and an 11th in the bass with the left had (D) what would this be called? Would it be an A minor 6add11?

Also what is the difference between a sus4 and an add11?
And (sorry for all the questions....) what makes a chord an add11 (or add6) rather than called an 11chord (or 6chord)

I think it would probably be A-6/D (i.e A-6 with a D in the bass)

The difference between an 11th chord and a sus 4 is that the 11th chord has the 3rd as well whereas in the sus 4 the 4th is a replacement for the 3rd. Similarly the difference between a 13 and a 6 chord is that the 13th has the 7th as well, whereas in the 6 chord the 6 is a replacement for the 7th.

When chords are specified with extensions (i.e. 9, 11, 13) they are in addition to the 1, 3, 5, 7 whereas using 4 or 6 they are replacements for one of the other chord tones.

does that mean that an A minor 6 would be 1, b3, 6?
And an A minor add6 would be 1, b3, 5, 6?

A minor 6 would be 1, b3, 5, 6.

I'm not sure what you mean by A minor add6, I don't think there's a distinction between this and A minor 6. If the 6th is in addition to the regular chord tones then it's a 13th, if it replaces the 7th it's a 6.

Unless you're talking classical theory? which could be completely different, the question implied jazz chords to me.

A minor chord (A,C,E) with a D and an F to my mind makes a chord of Dm9? (D,F,A,C,E). I expect I'm wrong, I usually look it all up before I post to make sure but I've had 3 large glasses of wine and I'm too "tired" to go upstairs and find my harmony books to check it out.

This is what I thought when I read the first post. I'd be more inclined to call it Dm9, or maybe Fmaj13, than Amb6. In isolation, it doesn't seem like an A minor chord at all, although in the right context I suppose it could be.

Dm9. ok that sounds cool -(this was for a friend who uses this chord arrangement a lot) so I can tell him he uses minor 9th chords?

I'm sorry about the am add6. I didn't mean that I was getting confused. I have this chord chart I found on the internet and I was trying to check if I understood how the chords were arranged. I needed a chart so I could understand the different shorthand names for chords and what they mean.

this is the chart I found:

the problem is if you pick on the specific keys the chords they are not always spelt correctly, flats are avoided for some reason which is annoying.
