Sine: Ear Training Gamesはどんなアプリ？
Sine: Ear Training Gamesは、自分の耳を鍛えることで絶対音感を養うための練習用アプリです。
比較対象となる音をあえて出さないため、提示された音の響きだけで正解を導き出す練習ができます。前の音が消える際に余韻を打ち消す処理が入っているため、一つひとつの音に集中しやすい環境です。最初は離れた二つの音から始まり、少しずつ音の数を増やしながら白鍵や黒鍵、和音など多様なパターンへ段階的に進めます。自分のペースで学習を進められるほか、これまでの進捗や苦手な音の傾向を記録する機能も備わっています。
耳を養う過程をゲーム感覚で取り入れたい人や、楽器の練習に取り入れたい方に適しています。特定の曲を弾く前に正確な音程を捉えたいときや、日常の隙間時間を利用して地道に聴力を磨きたい場面で役立ちます。

Ver 0.19.0 2026-10-30
Intro to harmony. Climb to the Glasshouse, where the lanterns light when notes sound together, and help its choir sing in parts again before the moonflower opens on midsummer night. Build chords on the lantern organ, hear major and minor, meet the four triads and the chords of a key, choose the chords for the choir's songs, and finish with Ode to Joy at the great door. The first three units are free.
The glacier in Bifrost Run. Outrun Fenrir and the bridge climbs onto the glacier under Jötunheim. Raise the shield with one thumb and lay planks with the other as frost giants throw boulders, then answer Hrungnir's rhythms as he throws them back. Quiet him for Skadi's scarf, and lay 1,000 planks in one run for Heimdall's horn. The glacier is part of Encore, and every run that outruns Fenrir tries its first stretch free.
Boons that change the run. Thor's lightning drives Fenrir back, Odin keeps your spark on a lap's first miss, Bragi builds the music and your multiplier twice as fast, and Heimdall, Idunn and Skadi give more too. Each boon comes on its god's card, and when one saves you, you see it happen. The timing check is easier to find, and every tap's word lands with a little more life.
Reading time. Sine's lines can stay up longer, or wait until you tap, in the lessons, the scenes and the games. Find it in Settings.
Sine says Do Re Mi. Sine can name notes Do Re Mi in the lessons while the keys keep C D E, or the other way round. Find it in Settings, under Solfège.
Gentler strings. Out of Tune's violins, violas, cellos and basses now play from softer recordings: their notes flow into each other and ring off naturally, in a warmer room.
Fixes. The music box at three o'clock on the Midnight Express plays again on phones, and the places you travel to between units now show in your language.

Intro to music theory is here. Sine leads you up Terrace Hill, from the long wall to the bell tower, teaching the keyboard, sharps and flats and the major scale, with pop quizzes along the way. The first three units are free.
Songbook Square is a new game. Busk at a street piano in the town square and play each song by its note names, by its shape, then by ear, as the band joins in. It comes with Encore, and the first three songs are free to try.
Sine now speaks Russian, Chinese and Japanese, and the language picker shows a flag for each language.
You’ll also find timpani in the instrument picker and C, the Out of Tune herald, in the wardrobe, both free. Games now keep moving with Reduce Motion on, and text fits on smaller phones in every language.

All aboard the Midnight Express.
• Out of Tune: the Midnight Express. Sine is the new conductor on a night train, and someone on board is putting the band out of tune. Ride from the platform at dusk to the Grand Exposition at sunrise, with rounds, puzzles and a mystery to solve, and outfits and a trophy along the way.
• Out of Tune on the high seas: the Open Sea and the Deep are open, all the way to the Kraken.
• Try both editions free. Their first levels are on the house, and they never use your plays.
• Sine Circles: Harmony is back. When more than half of your circle practises on the same day, your tree grows 30% faster, and the garden plays the chord you made together.
• The forest, rebuilt: the week's top ten circles, and a look round any of their gardens.
• New badges, two new practice rooms, and the first Tune-up is back as a Legacy game.
• Vibration can be switched off in Settings.
• Fixed: a dropped connection could occasionally start you over on a new account.

Our biggest update yet.
• The lessons, rebuilt in smaller steps: a warm-up for brand-new ears, then every note, up and down the octaves, one at a time. Everything you've passed is still yours.
• More of the course is free, now including Close calls and Up high: the white keys.
• Before each new note, Sine walks you through it on a piano.
• Every unit has a place of its own and a short scene as it begins. Now and then, something happens there at night: play it for a postcard. Finish Unit 1 and keep your eyes open for secrets.
• The circle tree: grow a tree with your friends over a year. Every answer waters it, and each stage is a new scene to explore.
• The trophy room: rewatch each trophy's scene, and meet Maggie the magpie, who looks after them.
• Day one: a trophy and the Founder outfit for everyone here during early access.
• Rivals has leagues, from Easy to Pro, and Ochoko has new levels.
• A real recorded guitar.
• Lessons always ask their own notes now, even after a tough run.
• Fixed: the Sine score's Tuning part could score a good run as zero, and a few sounds were slightly out of tune.

Ver 0.10.1 2026-10-16
A new Sine score. It now tests your ear in more ways than naming notes: find the player who’s out of tune, hold a note in your head through a run of others, and spot the note that changed in a melody. Each part gets its own result, and Sine travels from the sea to the desert as you go. Play a wind instrument? The test plays on yours, in your key.
Lessons that land. Each answer fills the key from where you tapped, and a run of right answers lights up around Sine, with flames as it grows, and shows on its face.
A summary that moves you on. Sine tells you how the lesson went, a piano shows which notes slipped, and the path shows how far you’ve come. A perfect score turns gold. If one note keeps slipping from lesson to lesson, Sine offers a Quick Practice of just that note.
Your streak on your Home Screen. Add Sine’s widget to see your streak at a glance, on the Home Screen or the Lock Screen. Sine gets a little more anxious as the day goes on, until you’ve played.

Sine Circles. Practise with friends in a room of your own, where everyone's Sine hangs out together. Play the same daily challenge and see who wears the crown, send note mail your friends open by ear, cheer each other on, and reach a weekly goal together for new outfits and backgrounds. Start one from your profile.
Out of Tune, the orchestra edition. An orchestra plays a famous piece and one player is out of tune: hold a player or a whole section to hear them alone, and call out the one who sounds off. From Rehearsal to Gala night, with Sine at the grand piano for the last concert. Free plays now come back every six hours.
Every instrument, free. Pick what Sine plays every lesson and game on, from guitar to tuba, without Encore. There's a violin now, and the cello is a real one, recorded, bow and all.
In your instrument's key. Play trumpet, clarinet, sax or horn? Pick your instrument's key in Settings and every note is named the way your music writes it, with the lessons in your key.
Tuned your way. Concert A can be 440 Hz or 442, as many orchestras tune, and the wash of sound between questions can run short, medium or long. Longer ones are busier too, so the last note really leaves your ear.
A profile of your own. Tap Sine at the top of Home to see your Sine score, trophies, streak and days played in one place. Choose which numbers show, and share a profile card. New backgrounds open up as you play on more days.
Sine in your language. The app now comes in Português (Brasil), Español, Français, 한국어, Bahasa Indonesia, Polski, Türkçe and ไทย: pick one in Settings. Note names can be Do Ré Mi too, spelled the way your country spells them.
A perfect score shines. A Sine score of 100 turns gold, and scoring 95 or more wins the Pristine trophy and Sine's Laureate outfit. Encore for life now comes with a conductor's tailcoat, and a year of Encore wins the Season ticket trophy.
A smoother Tune-up. Otto and the customers move as one piece, Sine is no longer cut off at the edges, and long sessions stay smoother: if your phone starts to fall behind, the shop holds its scenery still. Leaving in the middle of a run now asks first, so a stray swipe can't end it.
Fixes. Fewer freezes on Android, animations settle without bouncing, the band's trumpeter is crisp again, and the wave between questions shows again on phones.
