研究音乐表演中的表情的主要困难之一是数据的获取。虽然音频记录比比皆是，但在大规模音乐表演研究所需的精确度水平上，自动提取与时间，动力学和发音相关的精确信息仍然是不可能的。1989年，俄罗斯钢琴家Nikita Magaloff在Bosendorfer SE上演奏了Frederic Chopin的全部钢琴独奏作品，这是一架计算机控制的三角钢琴，可以精确测量演奏者的每一个键和踏板动作。在本文中，我们描述了这个集合，其中包括数十万个音符的准备过程和工具。然后，我们提出了初步的探索性研究的结果的表达内容的数据，特别是表演者的年龄，性能错误，手之间的重复，和克里思rubato的影响。我们还报告了初步的系统研究结果的形成特定的节奏通道，使用的概念相平面轨迹。最后，我们简要介绍了Magaloff数据是如何用来训练的性能渲染系统，赢得了2008年Rencon国际性能渲染大赛。
One of the main difficulties in studying expression in musical performance is the acquisition of data. While audio recordings abound, automatically extracting precise information related to timing, dynamics, and articulation is still not possible at the level of precision required for large-scale music performance studies. In 1989, the Russian pianist Nikita Magaloff performed essentially the entire works for solo piano by Frederic Chopin on a Bosendorfer SE, a computer-controlled grand piano that precisely measures every key and pedal action by the performer. In this paper, we describe the process and the tools for the preparation of this collection, which comprises hundreds of thousands of notes. We then move on to presenting the results of initial exploratory studies of the expressive content of the data, specifically effects of performer age, performance errors, between-hand asynchronies, and tempo rubato. We also report preliminary results of a systematic study of the shaping of particular rhythmic passages, using the notion of phase-plane trajectories. Finally, we briefly describe how the Magaloff data were used to train a performance rendering system that won the 2008 Rencon International Performance Rendering Contest.
