The classification of musical transformation: a conceptual approach to the knowledge organization of musical arrangements
Introduction. The purpose of this paper is to provide a conceptual analysis of the knowledge organization of musical arrangements found in notated Western art music.
Analysis. Four areas of arrangements are analysed. Inter-medium arrangements are explored, which are arrangements that transform one musical medium into another. Arrangements which involve changes of difficulty or pitch are discussed, as well as transformations between notation and performance. Arrangements of forms and genres are analysed, including sub-genres such as literal transcriptions, fantasies, virtuosic arrangements and pot-pourris. The function of arrangements is also discussed.
Results. This study introduces additional facets, foci and types of information. These include the development of musical themes as a classification principle, the concept of a performancearrangement, and the idea of functions specifically associated with transformation. A categorisation is proposed for the various types of form/genre arrangements, which shows blurred boundaries between types. The impact of time on arrangements is demonstrated, and that there is a non-binary division between the original and the arranged.
Conclusion. Two models demonstrate the complexities of musical arrangement, and how information specific to arrangements needs to be considered within music knowledge organization. Furthermore, the results suggest novel ideas about classifying change and transformation more generally

Webs of "Wirkung": Modelling the interconnectedness of classification schemes
This paper explores relationships between different classification schemes. It suggests how these relationships could be considered part of the reception of a scheme, in particular as an aspect of its "Wirkung". Both intra-domain and inter-domain scheme relationships are examined, and are combined with pre-existing research on intra-scheme relationships. A model is posited which maps inter-scheme relationships, showing some of the complexities evoked in analysing the connections between classification schemes. Musical instrument (organology) classification is used as examples throughout the paper, to illustrate the ideas being discussed
