時間軸の扱い方に焦点を当て,楽曲が持つ時間とのインタラクション手法を2種類提案する.1つ目は時間軸を視覚的に変形させることで時間の進行と音楽の進行のメンタルモデルをリンクさせる試みの“SeekRopes”である.2つ目は進行速度が異なる複数の時間軸を用い,音楽を構成する楽器の発音頻度を効率的に記述する試みの“Inception Sequencer”である.これら2つのシステムについて説明し,システムの評価と考察について音楽史の観点とインタラクションデザインの観点から述べる.
I propose two methods for interaction with time of musical composition by focusing on operating the time axis. The first one is that “SeekRopes” which links with the time flow and the music stream on mental model by visually transforming the time axis. The second one is that “Inception Sequencer” which is a challenging for efficient describing for the frequency of the sound of the instrument which composes the music, by a plurality of time axis which are ongoing with different speeds. I explain these two systems, and make an evaluation and consideration of the systems in the view of music history and interaction design.
