The Rainbow From That Day and Our AnthemSukima Suichi

Sukima Switch “The Rainbow of That Day and Our Anthem” Official Audio

Sukima Switch’s harmonies are basically the “lower harmony” in my mind.

The upper harmony is easy to grasp, but isn’t the lower harmony kind of hard to find by ear? Still, their two voices balance so well—I love it, and it always makes me want to harmonize! Especially in this song, the lower harmony right after the final chorus line of the hook feels amazing when it locks in, so that’s my top recommendation.

I think it’s fine to sing with about the same volume as Ohashi! The key with lower harmony is to support firmly without sticking out more than the lead vocal, so it might be tough to pitch at first, but do your best not to get pulled toward the main melody!

Released in August 2005, the track touched countless hearts as the theme song for TBS’s Sunday drama “Ima, Ai ni Yukimasu” (Be With You).

Precisely because it was created as the band overcame major changes, its words about the importance of supporting one another carry a special persuasiveness.

Sukima Switch – “Recipe of the Rainbow” Music Video: SUKIMASWITCH – NIJINORECIPI Music Video

“Rainbow Recipe” is a single by Sukima Switch released in 2009.

Here, the “rainbow” refers to the song itself.

The theme is songwriting.

A rainbow doesn’t always appear after it rains; it comes about through a mix of coincidences and inevitabilities.

I feel like songs are the same—they become something wonderful through a blend of chance and necessity.
