Formed on Girls Planet 999! Kep1er's Popular Songs (1–10)
WA DA DAKep1er1rank/position
Kep1er’s first mini album’s lead track “WA DA DA” is a hit that makes a strong impression of the group.
The song is divided into a powerful EDM-style section and a cute idol-like section.
Since the tone and vibe differ, it may help to be mindful of switching your dance style accordingly.
The beginning of the chorus has a strong beat, is catchy, very powerful, and still feminine.
In the latter half of the chorus, the choreography suddenly shifts to classic idol cuteness, so it’s crucial to switch from sharp, powerful movements in the first half to cute, playful movements in the second half.
If you can show that contrast in expression, it’ll be perfect!
