Recipe for Happiness

It’s the ending theme for the second season of the TV anime “The Apothecary Diaries,” a bittersweet yet warm love song that portrays Jinshi’s feelings for Maomao from his perspective.

In the version performed on THE FIRST TAKE, guitar-and-vocal is joined by piano, percussion, bass, and strings, and the emotional arrangement became a hot topic.

It’s a very relaxed song, and many anime fans might already know it.

For the vocals, the key is to project your voice in the low range of the first verse, and smoothly switch to falsetto in the chorus.

Try to lift the corners of your mouth and sing with a bright tone!

A Good DayHirai Dai19rank/position

Hirai Dai / A Good Day (Music Video)

The theme is a day off—a heartwarming slow number perfect for a relaxed day.

The song has an easygoing tempo with a laid-back groove you can sway to.

It feels more suited for daytime karaoke than nighttime! Since all the lyrics are in English, if that’s tough for you, I recommend slowing the playback speed on YouTube and going through the lyrics one by one.

If you get into the rhythm, the words will fall into place and it should be easy to sing! The vocal range isn’t too high, so loosen up your shoulders and sing in a relaxed way!
