Play along to the click and see how early or late you land, in milliseconds. Then mute the click and find out whether your pulse holds. Fully on-device: no cloud, no account. Set a tempo between 40 and 220 BPM and tap the big pad, or switch on mic detection and play your instrument. Each hit shows its offset; each session gives you a percentage and an average. • Click from 40 to 220 BPM • Tap, or let the mic detect your notes and claps • Hits, mean offset and spread for every session • Mute-click practice with drift feedback • A history graph of your sessions For drummers, bassists and anyone told they rush. Everyone gets five sessions a day. Pro, or SUS4 All-Access across the whole range, removes the daily limit. Made in the UK by working musicians.

《五線譜小學堂》是專為初學者設計的互動式音樂學習 App,把「看懂五線譜」這件事,拆成看得懂、唱得出、打得準三個步驟,一步步陪你練起來。 不用先懂一堆樂理名詞,跟著畫面動手做就會。 【四大練習】 • 認譜:看音符,把「唱名 / 音名 / 數字」對起來,用拖磁鐵的方式輕鬆記。 • 開口唱:按下麥克風唱出聲音,App 會即時聽你唱的音準不準,幫你抓出「以為唱對、其實跑掉」的音。 • 節拍:跟著真實小鼓打拍子,從報數提示到心中默數,由淺入深練穩節奏。 • 綜合:看譜+照節拍,一口氣把整條旋律唱完整。 【為老師設計】 • 老師可以照教學進度,自己出一條節奏題。 • 做好的題目能產生 QR 條碼,學生用 App 一掃,就把這條練習帶回自己的手機練(測試版功能)。 【適合誰】 剛開始學樂器、想看懂五線譜的人 想練視唱、音感、節奏的學生 需要出題給學生回家練的音樂老師 由潔特力樂器社親自設計,與初學者站在一起 完全免費 訂閱說明 老師訂閱:月 NT$69 / 年 NT$690,到期自動續訂。 可隨時在「設定」的 Apple 帳號訂閱項目中取消,取消後當期到期前仍可使用。 隱私政策:https://jieterlimusic.uk/staffschool/privacy 使用條款:https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
