Chaldni Pattern of an Acoustic Guitar Top

Capturing one of the modes (ring+) of an acoustic guitar top with signal generator and poppy seeds. A nice way of visualizing the tap tones of a free guitar top to help get the modes where we "want" them prior to assembling the guitar

@donepearce there´s serious people doing serious research, but it isn't difussion of this work; in fact when I was in Cremona, I know about the work of Carleen Maleen Hutchins with the lutherie school.

I agree, some luthiers waste their time , because they don't know how to apply this tecniques, I mean the basics, and finally becomes useles for the construction pourposes; only are usefull for research pourposes.

@TheMissing62 That doesn't mean it is right. In fact if that is the way it is "always" done, makers should stop wasting their time doing it.

@donepearce All the modal analisys is made ALWAYS with free plates, i.e.: separated tops and backs, even in the violin family instruments.

No, sorry but this is not cqapturing guitar modes. A guitar soundboard has a constrained edge, not a free edge. That makes all the difference in mode placement.

any chance of seeing the flip side to see how you brace your tops?
