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

Circular 27

A wide variety of fuels available in Alaska, their range in cost, and a diversity of heating applications often make the selection of a fuel an important and sometimes difficult task. While cost is important, other factors such as convenience, cleanliness, and adaptability to automatic control sometimes over-ride cost considerations, especially for home heating or crop drying

Remotely-actuated biomedical switch

Remotely-actuated biomedical switching circuit using transistors consumes no power in the off position and can be actuated by a single-frequency telemetry pulse to control implanted instrumentation. Silicon controlled rectifiers permit the circuit design which imposes zero drain on supply batteries when not in use
