在本篇論文中，我們設計了一種音樂教學以及編曲用途的輔助工具，讓使用者以最自然的彈奏方式將彈奏內容進行視覺化，以樂譜的形式記錄。我們開發了一光學式弦樂拾音器對弦樂器進行多弦同步收音，透過對每條弦個別收音的方式分析每一條弦行頻譜，進而判斷使用者正在彈奏哪一條弦的哪一格。本論文也開發了一套結合前述光學拾音器之應用軟體，可在使用者彈奏的過程中即時地顯示彈奏的把位、指型，並且記錄彈奏的資訊，進一步轉換成讓初學者更容易閱讀的樂譜—TAB。

In this paper, we design an musical string instrument auxiliary tool for teaching and music composing. Our system provide an user interaction which is intuitive instrument playing style for musicians, and visualize playing content which user had played. We develop an optical string instrument pickups that capture the string vibrating signal for each string. Our system deploys optical pickup units to each string for achieving individual string reception. With pitch detection and onset detection, our system can recognize which string has been toggled, and where is the string been pressed. We also develop a software application for the optical pickups. The application includes real-time fingerboard visualization and sheet music translation.
