Giovanni Pierluigi da Palestrina: catalogue of works. Online-database and critical presentation of the sources.

计划中的帕莱斯特里纳作品在线目录的目标是收集数据库中帕莱斯特里纳（825）所有现存作品的所有已知来源（目前已知：约22,300）的所有相关书目数据。此外，基于它们最重要的来源，这些作品将被数字化（处理模式：通过基于文本的音乐雕刻程序LilyPond，以测量符号的原始部分的真实副本-但在乐谱安排中）和可视化，包括不同来源之间的变体的呈现，由程序自动生成。除了通常的数据库搜索方法之外，还有机会搜索乐谱中的各种音乐参数和结构背景。数据库软件（用Java编写）已经完成，几乎完成了。特别是基本的音乐搜索功能几乎没有bug（搜索旋律，搜索纯粹的音高或节奏模式等）。在下一次，这些搜索方法应该由能够搜索复调结构的程序来补充。该项目的创新元素是将作品目录和资源索引与数字化乐谱编排中音乐资源再现的可视化相结合。与印刷的作品目录相比，这使得科学和音乐实践之间的各种接口成为可能。通过上述变体的呈现，可以在特定的历史、地理和社会历史背景下描绘表演实践的具体特征。这可能为当代演奏实践创造新的方式，因为它将有可能从一部作品的现存版本的剧目中产生个人的乐谱，这些乐谱反映了特定的历史表演传统。

The projected online catalogue of the works of Palestrina has the goal to gather all relevant bibliographical data of all known sources (currently known: ca. 22,300) for every extant work by Palestrina (825) in a database. Furthermore, based on their most important sources, these works will be digitized (mode of proceeding: true copy of the original parts in mensural notation - but in score arrangement - by means of the text-based music engraving program LilyPond) and visualized, including the presentation of variants between the different sources, automatically generated by the program. Apart from the usual methods of database search there will be opportunities to search for various musical parameters and structural contexts in the scores. The database software (written in Java) was already worked out and is almost complete. In particular the fundamental musical search functions are running almost bug-free (search for melodies; search for purely pitch or rhythmic patterns etc.). In the next time these search methods should be supplemented by procedures which enable the search for polyphonic structures. The innovative element of this project is the combination of a work catalogue and index of sources with a visualization of reproductions of musical sources in digitized score arrangement. This allows - in contrast to printed catalogues of works – various interfaces between science and musical practice. By means of the above-mentioned presentation of variants it will be possible to depict specific characteristics of performance practice in a particular historical, geographical and socio-historical context. This could create new ways for contemporary performance practice, because it will be possible to produce individual scores from the repertory of surviving versions of a work, scores, which reflect specific historical performance traditions.
