Communities showing the mesoscopic network structure.

<p>On the mesoscopic scale the network is characterized by tightly-knit communities. We show four major communities. We show which musician attributes (composer periods, performer positions, and musician nationalities) are overrepresented in each community. Community A, for instance, represents the Austrian-German Romantic music; B represents the USA-based Modern music; C represents the transitional period between Romantic and Post-Romantic; finally, D represents the classical guitar.
