This is “Apt.102” from “Kirby’s Epic Yarn” developed by Good-Feel, published by Nintendo.
This is composed by Tomoya Tomita.
It is a peaceful bossa nova style song.
This game has no concept of health, and therefore no game over.
This is probably because the design of this game focuses on “enjoying what’s happening on the screen”.
This game was initially developed as a game using a original character (Prince Fluff).
When the direction of the game became unclear and development stalled, Nintendo suggested the idea of using Kirby as the main character.
As a result, the game was released as this title.
The harmonics at the end of the song should be placed slightly closer to the 4th fret, as described “<3.2>” on the sheet music.
