ty for trying to help but i think many of u are missing the reason why im confused..
ive read somewhere that chords like C9, is root/3rd/5th/b7/9 where as Cadd9 is C + D, and i cant find it anymore.. im gonna do some research so as not to bother u guys with noob questions. I understand also that these can be played all over the neck, and thats exactly why im asking, because sometimes id prefer to play a different C2 than the one they have listed, and i understand substitutions happen all the time and really shudnt be a big problem but thats not the point.\
they can be identical tho right?
x32030 is C2 and Cadd9 right? C E G D E = Cadd9? or Cadd2? or C2? see why im confused now?
x32030 is Cadd9, (and add 10 too!) C major is C,E,G. When a Chord is accompanied by a number, you
can add the chordal extensions to reach the interval indicated. C9 would be C,E,G,B(b),D. Cadd9 would be C + the ninth note of the scale so C,E,G,D. C2 however should be, C,D,E,G. Although the letter is the same in C2 and C9, the harmony created by each version is different. There's a lot more tension created by playing say, 52xxxx vs 5xx3xx. The reason why inversions are accepted as the same chords on a guitar is because of the physical layout of the guitar. Playing minor 2nds is very tricky if you're not using open strings. E is impossible to play as Root, Third, Fifth in first position, using the 6th string, unless you re-tune your guitar since the Third in the Key is only available on the same string as the root! No one write E581012OV8, it's just widely accepted as "E". Mind you the triad appears at 8,10,12.
I think a more complicated question is why are there chords labeled E13 when there are only 12 notes in the chromatic scale!?!?
