The five basic open-hole tones of the standard shakuhachi give you D, F, G, A, and C. This is the folk scale of Japan and happens to be very close to a D minor blues. I believe the shakuhachi fits into this jazz context very well, as do the classical guitar and string quartet, though none of these instruments are typically found playing Pentasonic blues.
