Extraction of sensitivity information from improvised jazz playing and its presentation by picture

在这两年中，我们取得了以下成果：我们从一些乐器的音乐原始数据中大力提取灵敏度信息。对于电码仪，可以在考虑之前的基准的情况下获得灵敏度的连续性，同时可以得到瞬时音调，为后续的研究提供了延伸。对于鼓类乐器，我们可以通过考虑鼓类部件的种类来区分保持节奏的部件和灵敏度的部件，比之前的方法更容易。对于低音乐器，与以往使用码音的方法相比，可以很容易地确定瞬时音。但由于研究时间的限制，无法获得低音的灵敏度信息。对于旋律乐器，张力是由偏离音阶的程度来确定的，我们认为这种张力符合音阶演奏的条件。在我们提出的工作计划中，我们无法在计划时间内完成下一个课题：从拍摆和低音演奏中提取灵敏度，将提取的灵敏度信息转换为图像，使用现场音乐家的数据进行研究，构建交互式会话系统，对我们的系统进行总体评估。分布式成本的主要用途是购买个人电脑、音乐管理软件、标准MIDI文件等消费科目，以及在社会上口头展示的差旅费和现场音乐人的报酬。在1998年和1999年日本电子信息与通信工程学会（IEICE）大会上进行了电码仪器研究的口头报告。

In these 2 years we have got results as follows :We extract sensitivity information from music primitive data for some instruments vigorously. For code instrument, continuity of sensitivity is able to be got to consider a previous datum, and instantaneous tone is got for extension of our following research. For drum instrument, we are able to separate parts for rhythm keeping and parts for sensitivity by considering kinds of drum parts, easier than as compared with the previous method. For bass instrument, instantaneous tone is easily decided as compared with the previous method using code instrument. But sensitivity information from bass is not able to be got for the constraint of our research time. For melody instrument, tension is got from degree of deviation from scale, and we represent the condition of this tension agrees with cromatic scale playing.In our proposed working plan, we can not finish next subjects within the schedule time : extraction of sensitivities from beat swing and from bass playing, conversion to picture from extracted sensitivity information, study using data of live musician, construction of interactive session system and total appraisal of our system.The main uses of distributed cost is purchases of personal computer, software of musical management, standard MIDI files and other consumption subjects, and traveling expenses for oral presentation in the society and reward for live musicians.The oral presentations of study of code instrument are performed at 1998 and 1999 IEICE (The institute of electronic, information and communication engineering in Japan) General Conference.
