back number – fish (full)

A bittersweet yet beautiful “Scab Song” that portrays a woman’s wavering heart in the face of parting.

Cherished since their indie days, this special track was completed under the production of Masanori Shimada, blending delicate lyrics with a grand sound.

The overall vocal range is a relatively calm F3–A#4, and the song itself has a gentle mood; since it surges all at once in the chorus, the key is to really project your voice.

There are many sustained phrase endings, so focusing on diaphragmatic breathing and taking deep breaths should make it easier to sing.

Heroineback number9rank/position

back number – Heroine (full)

The 11th single by back number, a bittersweet unrequited-love song set against a wintry backdrop.

Released in January 2015, it was featured as JR East’s “JR SKISKI” campaign song and in Kirin’s Tanrei Green Label commercials, winning broad support as one of the band’s signature winter staples.

Overflowing feelings for the other person contrast with a lack of self-confidence and the frustration of being unable to take a step forward—expressed through plainspoken lyrics and a warm band sound.

Producer Takeshi Kobayashi’s arrangement further accentuates the song’s fragile beauty.

It’s the perfect track to convey sincere, if awkward, feelings when you go to karaoke with the woman you like.

A poignant ballad by back number that quietly sings of lingering feelings and a sense of loss for a former lover.

Released in October 2011 as their third single, the song is also included on the album “Superstar,” which came out the same month.

Fear of memories of the other fading intertwines with the resignation that they will eventually be forgotten, and the realization that the time spent with the person was part of oneself wells up with aching tenderness.

A song that offers comfort to anyone who has lost someone dear.

Letterback number13rank/position

back number – Letter (full)

Released on August 12, 2015, this medium-tempo ballad sincerely—if a bit shyly—expresses gratitude and love for parents living far away.

Produced by Takeshi Kobayashi and featured in an NTT Docomo commercial, it’s a warm classic that resonates across generations.

The overall vocal range is D3–C5, with the highest falsetto note appearing in the bridge; if you can get through that part, it should be a relatively easy song to sing overall.

High falsetto takes a lot of breath, so the key is to project your voice straight upward, as if aiming directly above your head.
