C2 chord?

richardgk · #1 02-20-2010, 10:18 PM

Band in a box spat out this chord: C2.

I have never seen this before, can someone please explain this to me?

somedumbguy · #2 02-20-2010, 10:19 PM

Replace the 3 with the 2. In this case - C, D, and G.

Chrisk-K · #3 02-20-2010, 10:19 PM

It probably means Csus2.

TheBasicBassist · #4 02-20-2010, 10:21 PM

It's a sus chord.
A Cmaj chord is C-E-G
Cmin is C-Eb-G
Csus2 is C-D-G
Csus4 is C-F-G
Cdim is C-Eb-Gb

Your substituting the interval of a major third (above the root)
for a major second (above the root).

thank you all

It's a Cadd9. I found it in a guitar version of Imagine and said "excuse me?" Then someone told me it is a Cadd9 with the open D string. I don't know there's much difference in the sound.

If you leave the D string open, you still have the 9th, and with the high E string open you still have the triad of C E G. You have C D G D E. I don't know that there's much difference in the sound.

Yes it's Cadd9

Quote:

C 2
a.k.a.: on guitar equivalent to: Cadd9
intervals: 1,2,3,5
half-steps: 2-2-3
notes: C,D,E,G

Guitar not handy, just tried the two on keyboard, not that much difference between the two.

cb56 · #8 02-21-2010, 06:40 AM

no, it's not a C add9.
a C add9 has the note "E" in it.
A C2 does not have the note "E" in it.

as stated above, a C2 has the notes C, D, G. only

MalcolmAmos · #9 02-21-2010, 06:55 AM

http://www.google.com/search?sourcei...2+chord+guitar Looks like this has been asked before.

Seems like Praise guitar uses the C2 quite a lot and they would omit the 3 and others would include it. Sound wise I really do not hear all that much difference. Which ever is easier for you works for me.

C2 fingering - not sounding the 1st string E is straight forward (easy) if you do sound the E string, by mistake, I doubt anyone would hear the difference.

Cadd9 would be sorta the same as saying C2 but the D would always be on top of the chord (in the 9th place).

C9 would not be the same as C2 because C9 has the 7th in it. Like, C7, C9, C11, C13 etc..., all start with a C7.

Csus2 would not be the same because it would have the fourth (F) in it, that's what makes it a suspended chord.

"C2" is just a C major with a D (2nd step) in it.

C2= C,G,D
C2= C,E,G,D
C2= C,G,C,D,G
C2= C,D,G,C etc...,

different voicings of the same chord. Just getting the 2nd (the D) in there. Of course the same applies to all twelve keys.

I use that 2 on all sorts of chords when I am *cough* not playing bass...

. It's a cool sound.

On bass you can play it C, G, D if you stretch your hand a bit (A string 3rd fret; D - 5th fret and G - 7th fret). Cool sound IMO and you can move it around like Jaco does on that Modern bass instructional video where he jams with himself.

The E does not have to be excluded every time you play a C2.
It can be left out and often is regardless of what C chord is being played, but it can be in there.

Can't all the notes just get along?

The problem is that there is NO standardized definition for a C(2) chord. I've seen it interpreted to mean C add9 (CEGD) and also to mean Csus2 (CDG). The use of the term "sus" in Csus2 is a bit of a stretch as well since traditionally, a "sus" (suspension) involved raising the 3rd to the 4th scale degree (usually on a V chord). A "sus2" lowers the 3rd to the 2nd scale degree. I've never seen it involve the 4th but I'm sure someone has interpreted it like (CDFG).

There are exceptions, and people are not always strict about this, but IME, if someone writes Cadd9, usually they mean just that: CEGD. If they write C2, they are generally specifically asking that the 3 not be part of the chord, hence CDG. This doesn't mean an E can never be played when you play under the chord, just that the chordal instruments are being instructed to prefer voicings that don't use the E.

Often you can substitute Cadd9 and no harm is done; people may not even notice or care. But sometimes the sound without the 3rd is specifically what's wanted. Technically they are two different chords, as cb56 pointed out.

IME this is not exactly the case. Not all sus chords have the 4th. That's not what makes it a suspended chord. What distinguishes a sus chord is simply that the 3rd is replaced. The key pioint, however, is that it may be replaced EITHER by the 4th (sus4) or the 2nd (sus2); that's why we have those two terms. It's common to use sus in place of sus4, because that's probably the more common type, but it's not exactly correct. The correct term would be sus4. A sus2 would not have the 4th, it would have only root, 2nd, 5th.

A C9 chord, typically, has the note D voiced outside of the octave whilst the Csus2 or C2 chord is voiced within the octave and omits the third.

I don't think that's necessarily true. I think things are more flexible than that. For instance, a common way of voicing C2 on guitar (which I mention because i know it better than piano) is, from low to high, C C D G. You could also do it C G D.

A problem you get into when you think about voicing within or outside the octave is, whose octave(s) are we talking about? Think about a band with two guitars, a keyboard, and a bass. How many octaves are we talking about here, and where exactly would the D have to be to be considered "within" or "outside" the octave?

He's likely going by the classical definition of suspension. Technically, if you want to get into counterpoint, there can't be a suspension of a note that resolves upwards - that's against the very definition of suspension. If it resolves upwards, it would be a retardation, and I'm not sure if too many people would adopt the nomenclature "Cretard2".

There can of course be a suspension of the second over the root (9-8 suspension), but then you get into contrapuntal patterns that are wholly foreign to our system of chord symbology. The whole concept of "sus" in contemporary and popular music is different than that in the common practice so its important not to get confused by the two. "Sus" in contemporary music means a chord that has another note substituted for the third.

Voicings matter, whether you like it or not. "Cadd9" and "Cadd2" can mean two different things. Cadd2 has a different history as a voicing than Cadd9 - it was first adopted as a way to explain how a lap steel player articulates the major third in a chord in country/country rock music - usually by playing the major second as an appogiatura. This sound can be approximated on piano, and the chord symbol Cadd2 is used to reflect that. The 2 HAS to be next the third for the lapsteel effect. Cadd9 doesn't have any of these connotations, and so the 9 is placed in a different octave to the third.

but there is indeed a difference and I for one would hear the difference.
