沒有老師在旁邊,也能好好開始學小提琴。 我是胡老師,教琴、修琴很多年,也寫過小提琴自學書。這支 APP 就是把書裡教的,一步一步搬進手機裡:從認識這把琴、怎麼夾琴持弓,到拉出你的第一首歌。 小提琴難在它沒有格子,音準要靠自己的耳朵找。但反過來想 — 你只要會唱一首歌,你就有能力把它拉出來。 【 一步一步的課程 】 從「認識你的小提琴」開始,姿勢、持弓、調音、空弦、弓的走法、看譜、拍子、指位、音階,一課一個重點,每課都有小測驗確認你真的懂了。 【 拉給 APP 聽,它會告訴你準不準 】 跟著畫面上的譜拉,APP 用麥克風聽你的音準與節奏,拉對的音會亮起來,整首拉完會告訴你哪裡要再練。拍子跟不上?打開節拍器,示範和你自己拉都會跟著打拍。 【 簡譜、五線譜隨你切 】 看不懂五線譜沒關係,先用簡譜的數字入門,同一首曲子隨時可以切換兩種譜對照著看。譜會跟著你拉到哪裡自動捲動。 【 曲目(都是耳熟能詳的) 】 小星星、瑪麗有隻小綿羊、歡樂頌、兩隻老虎、平安夜、聖誕鈴聲、生日快樂、奇異恩典、望春風、雨夜花、恭喜恭喜。 【 隨手可用的工具 】 · 調音器 — 拉一下,告訴你弦要轉鬆還是轉緊 · 節拍器 — 設好速度與拍號,跟著踩 · 音準訓練器 — 專門練「聽得出高低」 · 拉拉看小提琴 — 沒帶琴的時候,在手機上左手按位置、右手拉弓 · 音階表 — 照書重繪,每個位置點下去都會發出那個音 【 給還沒買琴的人 】 在「設定」裡可以解鎖全部課程先看看內容,不用有琴也能先了解學小提琴是怎麼一回事。 【 關於聲音 】 所有示範都是小提琴音色,不是電子音。課程與工具的核心功能都在手機本機運作,不需要網路。 慢慢來,有耐心。拉不好不是你的問題,是還沒練到而已。 潔特力樂器社 Jieterli Music 官網:https://jieterlimusic.uk
