So this means low density and low Young's modulus (i.e., low stiffness)?

The title, found in the midst of a few other papers on torrefaction, etc:
"Perceptual evaluation of bracewood and soundboard wood variations on the preference of a steel-string acoustic guitar"
Yes, for this particular model and design of guitar, the best top wood, in two separate and independent runs of the experiment, was the lower density and lower stiffness Sitka spruce. The high density/high stiffness wood showed a signifcantly lower preference score, based on pairwise comparisons in listening tests with 23 guitarists, both pro and amateur.
