Even the clause of another name of the CDEFGAB touched it a little, but says the code that 9th 11th 13th was added to with a tension chord. I usually become the form that Buddhist preaching increases on a seventh chord.
A tension chord including 9th
I introduce two kinds of C9 and Cadd9. C9 means m7th that is the chord which increased 9th in C7 by the tacit consent. Please be careful not to make a mistake because the thing which added 9th to C is Cadd9.
C9("9th" add to C7)
The nine chord that there is a funky impression is a super frequent appearance chord by the funk cutting.
Cadd9("9th" add to C)
With a chord with a feeling of transparence, it seems to match refreshing music brightly.
A tension chord including 11th
11th (four times) becomes muddy so that 11th is next to ,M3rd by a semitone when I add it to C7 and hears it. Because I am not much common use-like, I introduce only Cm7(11).
A tension chord including 13th
I am careful not to mistake it for C6. 6th is treated as tension called 13th when I add 13th (six times) to a seventh chord such as C7.
A, in addition, strange chord
I introduce the chord which I am slightly special, and is interesting (and it is used well comparatively) which I am hard to classify here.
A diminish chord
Cdim(There is all the distance of the sound in 1 sound and a half)
#9th / b9th tension
C7(#9) / C7(b9)
