The Zhou Dynasty (10th to 7th century BC), established a formal system of court and ceremonial music (later called “Yayue” - meaning 'elegant music') which embraced the concept of music as a cosmological manifestation of sounds found in nature and integrated into the dual universal order of yin and yang.

Music began in China 1000’s of years ago as evidenced by excavations in Henan uncovering bone flutes dating back 8,000 years, and clay music instruments in Xi'an dating back 6,000 years. She sings “I can’t help feeling / We could have had it all (You’re gonna wish you never had met me) / Rolling in the deep.” After that point, she repeats rolling in the deep throughout the song for an intense emotional effect as she sings about her grief over the end of the relationship.The ancient chime bells produce melodious tune.

The first time it appears is during the climax of the song, which starts in a pretty low-key way. The line rolling in the deep appears several times throughout the song.

Roll deep (which is used as a verb) has existed since at least the 1990s and has a meaning that could be approximated to having a close personal relationship with one or more people. So what does rolling in the deep mean? Adele herself has stated that she adapted the lyric from the expression roll deep. In an interview, she says that the lyrics are telling him to “get the fuck out of house instead of begging him to come back.” The song has been hugely popular and by 2017, its official music video had over one billion views on YouTube. The song itself describes the singer’s vengeful feelings toward an ex-boyfriend. Rolling in the deep is a lyric that originally appeared in the 2010 hit Adele song of the same name.
