Step-by-step explanation:
The artwork 'Bold, Double, Barline (Variation # 2)' by Jennie C. Jones is significant because it embodies all three presented aspects: 1) It draws influence from jazz music, reflecting Jones's interest in the symbiotic relationship between visual art and music. 2) The artwork can be seen as a reflection of the physical residue of music in the sense that it captures the essence and rhythm of jazz in a visual form. 3) Rather than utilizing traditional paint, the artist employs acoustic sound-absorbing panels often found in sound-engineering to create her pieces, thus making a direct reference to sound and music through her choice of materials.
