A bipartite network that connects music styles with instruments is constructed.

<p>(A) Schematic representation of the data containing the relations between styles and instruments. (B) Visualization of the matrix describing the music production network, . A black (white) field for style and instrument indicates that . (C) Part of the bipartite network that connects music styles with instruments for a given year . Large nodes represent music styles, small ones instruments. It is apparent that some instruments occur in almost every style while others are used by a substantially smaller number of styles. For instance, there are only two instruments appearing exclusively in ‘hip hop’ among these five styles (for example the flageolet) whereas dozens of instruments are only related to ‘experimental’ (such as countertenor vocals). Vocals, lead guitar, and drums, on the other hand, appear in each of the five styles, whereas bones used as percussion elements only appear in ‘Black Metal’.
