Acoustic guitar resonance

Go to a guitar store and play the highest quality acoustic you can find (maybe bring a right-handed player with you). See if you hear this harmonic on a Taylor or Martin or some other higher-end piece. Maybe your builder is more concerned about his ego than his product, eh?

What is a "produced tone" and what other sorts of "tone" are there?

:D

What I mean, is over- and under-tones that are not the primary tone of a particular sting/fret combination. When I play each string in turn, I get EeAaDdGgbbee, but when I play only the octave g, I can finger-mute that string, and both my ear and a tuner tell me the g is still being sounded. Working from memory (too lazy to go downstairs and find out for sure,) that tone is coming from the d string, plus one other- even though they are tuned to different pitches. A previous 12-string guitar I had (a Ventura,) did not do that nearly as much.

I really thought "produced tone" was the proper term for these over- and under-tones, but a google search came up dry, so I am not sure if I am remembering my theory correctly. I suppose "harmonics" is either a "better" term, or at least more recognized. But I am sure I am remembering the experience, as described, correctly, even if I am blanking on some of the details.

Of all the 12's I have heard, this one seems to have the most "delicate" tone, too.
 
Could be, but trust me if I say the guy really knows his stuff.
Maybe it's just me, I'm not a very good player.

They called sympathetic vibrations. That is not what we are dealing with here.

Any tone on a guitar is a product of the frequency of the note and the harmonic series of that note. Nothing else. Further tone colouration is added by the body itself and the materials that it is made of. They still relate to the notes fundemental and resulting harmonic series. Any other "tones" present are generally unwelcome because they either selectively boost of cut the amplitude or vibrate at a dissonant pitch to the sounding fundamental of the note. Some also are just unpleasant to the ear, a badly cut and rattling string slot for example..

I'm telling you "twice", the guitar is fine occording to the shop owner. ( professional guitar builder)
"This is completely normal" he said, he even tried it on a better guitar which also has this "harmonic"

I've also told him about your solution, but he said the guitar is fine.

If the guitar is fine, why do I keep hearing this "harmonic" so loudly?

Either your guitar, you or your "guitar builder" buddy is lying. Which is it?

Could you please confrim this Asus2/D chord?

Thanks in advance

That is a strange sound your guitar has.

If I was using that chord in the key of A, I would call it A9sus4.

In the key of A it comprises of Root [A], 4th [D], 5th [E] and 9th .

[1,4,5,9]

Chord description really depends on what type of music you play. I never refer to a 2nd, as your chord description says suspended 2nd, I always call it a 9th. Where as I do refer to a 4th as a suspended 4th, your chord labels it /D.

I am guessing here; but maybe a country musician might call it Asus2/d, someone who plays Jazz might call it A9sus4, and another genre may have another name.

Its up to you which naming convention you choose to use.

Chord names are dependant on the intervals with in them and on occasion if some intervals are common the key in which the piece is written. It has nothing to do with genre.

I totally agree it is about the intervals and I also expected someone to totally disagree with what I said. :spank:

Is it an augmented 4th or a b5?

I know only one of the above appears in my composition notebook.

I framed my answer at the op to provoke thought, or maybe to get him/her inqusitive enough to learn a little about intervals and chords.


Is that your daughter in your sig?

It matters not what you wish to provoke in the OP. It is what it is. A chord is described by some very clear and simple rules.

lol. gud one.
 
The reason I wouldn't call it a "/D" is that that's, to the best of my knowledge (and I'm not hugely versed in theory) what's called a "slash" chord, and the "D" part of it after the slash denotes the bass note. That's my experience, but I could be wrong, which is why I said "I" wouldn't call it an Asus2/D - the chord diagram indicates that there is not one, but two notes lower in the chord (A and E) than the D, "I'd" thus not call it an Asus2/D because you're not playing the D as a bass note.

I've seen 002200 called Asus2 (I never know which way to write these things but this ---> is the low side...). I'm not sure that's what I'd call it, but it'll do for now.

In lowering the E on the third string to D, you're introducing a 4th or 11th into the chord and removing a 5th. There's another 5th still there in the high open E string. If it's an A chord and you're playing the open low A string, you have a 5th, an A, a 4th, a higher A, a 2nd or 9th, and a higher 5th...

What does all this mean it's called? I don't know...

What I would say to you is that there are a million singer guitarists who never really learn their instrument well and are always looking for easy chord variations, often by just removing a finger from an existing chord and sounding the open string - this is another example of that practice.... use these things sparingly or you'll sound like a million other people..

The chord is what it is and it's name is relative to it's component intervals and the key in which it is associated with. All chords are named that way. It doesn't need over analysing for some troll on a bbs.
 
002200 is A5 power chord ain't it? Or maybe that's x022xx. x02xxx? I don't fuckin' know. I'm one of them guys. I just play it.
