Keywords are: new pedagogical paradigms, musically relevant material, modular course design, reusable resources and tools, wide area networks, distributed technical infrastructure, object database with web gateway. This paper reports in particular on the recent development of educational materials at the Royal Conservatory in The Hague and on the realization of the technical infrastructure, designed in collaboration with the University of Glasgow and the Musikhochschule in Hannover. 1. Introduction The European project group "MusicWeb" was founded in January 1995, with the objectives to discuss the problems of computer-aided music education and develop solutions for them. Since 1996, the year the last paper of the MusicWeb project was presented at the ICMC conference in Hong Kong (Boehm, de Jong and Hempel, 1996), the MusicWeb project has become a framework in which different institutions develop their own projects. At the moment active partners are the University of Glasgow, the Royal Conservatory of The Hague and the Musikhochschule Hannover. This paper will introduce concisely the current state of affairs, and report on the development of educational materials in The Hague. 2. Project sites As mentioned, three different sites are actively involved at this moment. In Hannover and The Hague we focus on the use of communication and information technology in the process of teaching and learning. Glasgow is mainly concerned with the technical infrastructure of M~usic~eb. The Musikhochschule in Hannover is investigating the use of computers and information technology within the classroom. Two primary schools take part in a project that offers teachers and students access to a great variety of music-educational resources through the internet. During the classes, the computer may be used to supply information and produce printouts of material. Today in The Hague we are developing applications and authoring tools that in the future will support learning activities in the regular music theory curriculum. These applications will be made available through dedicated workstations in the library of the Conservatory. They will also be available on the internet, through a login procedure. In Glasgow a distributed technical infrastructure, including a link and an object database, a media server for streaming and a web gateway, is administered and serviced by the Performing Arts Data Service (PADS) in cooperation with the Department of Music. This infrastructure has the advantage that the authoring sites can concentrate on the creation of educational material, while using an up-to-date web server and media technologies, administered in Glasgow.

Technical Infrastructure The system in Glasgow consists of two Silicon Graphics (SGI) Origin 200 servers: one is a media server streaming audio and video using SGI MediaBase software; the other runs an object-oriented database with a web gateway (Hyperwave Information Server) which stores the links, the data and the metadata of the material on both servers. When sound files are stored locally to ensure fast access and high quality, objects can be indexed and their metadata stored on the central server C7 / &.q. Den H&~g 3...............................s o u n d lile s figure 1: technical infrastructure The features of the technical infrastructure: * Use of web gateways connected to an object-based database server system * Separate link management or link databases, enabling automatic hyperlink consistency * Storage of resources of any type, including simple, complex and composite * Storage of resources anywhere, remote or locally, or distributed on different servers (server-pool) * Use of graphical access or browsing techniques * Controlled user access through rights and access management * Scalable delivery mechanisms * Modular and open protocol architecture enabling access to relational database management systems, catalogues and other future data servers and data clients * Storage of metadata such as attributes of the object belonging to the metadata, thus achieving a "natural" integration of resource collections and their catalogues * Detailed collection-specific user-access statistics 4. MusicWeb The Hague A pilot project started at the Royal Conservatory in September 1997. This two-year project has the following objectives: * to develop new pedagogical paradigms for the fields of aural training, analysis and harmony, using existing technology in a networked environment * to design reusable modules, resources and tools for both teachers and students * to make learning with this system a primarily musical experience, with the emphasis on the relation between practice and theory * to develop authoring guidelines outlining standard methodologies for designing courseware-materials within the MusicWeb context * to integrate MusicWeb with the existing curriculum
