Find a face, tap it
Tap a tile and the face is on your clipboard. The groups go by what the face is doing: singing, humming, whistling, dancing, wearing headphones, holding a microphone or playing something. Then come notes with no face, and faces with a Japanese word. Search reads the labels: karaoke finds 9, headphones 10, and off key finds (°ロ°)♪ and (°ロ°)o¶♪ (>_<).
The four notes in a music note kaomoji
♩ is Quarter note, a crotchet in British English. ♪ is Eighth note, a quaver. ♫ is Beamed eighth notes, and ♬ is Beamed sixteenth notes, a pair of semiquavers. They sit side by side in Unicode, U+2669 to U+266C, and (・∀・)/ ♩ ♪ ♫ ♬ counts through them in that order.
Tips
Headphones are two half circles, ◖ ◗, or a d and a b: d(-_-)b♪ needs only a keyboard and one note.
The microphone in (´〇｀)o¶～♪ is Pilcrow sign, the paragraph mark. Two other mics are the Greek letters ρ and θ.
～♪ is the shortest at 2 code points. Short keeps the 27 of 6 or fewer. Everyday characters hides the 4 that borrow a character.
Questions and answers
Is ♪ an emoji?
No. ♪ is Eighth note, U+266A, and Unicode's emoji data file does not give it the Emoji property. The same goes for ♩, ♫ and ♬. The musical note emoji is a separate character, U+1F3B5, and no face here uses it.
Is there a kaomoji with headphones?
Yes, nine. Five wear half circles for ear cups, as in ◖(˘ω˘)◗♪, and four use a d and a b, as in ♪ d[^_^]b ♪. Search headphones and a tenth joins them, with 音楽, ongaku, the Japanese word for music.
What does 鼻歌 mean?
Humming. Wiktionary reads 鼻歌 as hanauta and builds it from 鼻, nose, and 歌, song. It is on (^‿^)♪ 鼻歌 in the last group, next to 口笛, kuchibue, a whistle with the mouth, and ノリノリ, norinori, in high spirits.
Where are the faces with a note and a heart or a star?
On the heart, star, sparkle and flower pages. This family files each face once, and those four props outrank a note, so a face holding a heart and a note is a heart kaomoji. A face lands here when notes are its only prop.
