A good luthier will tap-test a guitar in the manner you have pictured, by sprinkling graphite on it. Some luthiers can do it by ear alone, but the graphite patterns are a more empirical way of doing it, I suppose. The patterns determine where the guitar needs to be braced to produce a particular sound--for finger-style playing, bluegrass sound, classical, etc. (I didn't know that....my husband is a musician/guitarist.)
