Answer:
Musical lyrics.
Explanation:
"The Great Wave", a famous painting of a seascape with Mt. Fiji in the background was done by Hokusai, a Japanese painter. This painting reflected the newly emerging nation of Japan and how it is 'coming' into the world.
When Neil MacGregor presented this painting to the audience in Japan, the director of London's British Museum presents how this painting came to emerge. He also focused on how the Asian nation 'grew' slowly while the world is occupied with 'wars'. And in his rhythmic presentation, MacGregor used a musical lyric as his outside source.
