Music publishers and music consumers (theatres, orchestras, music schools, libraries, musicians) are strongly interested in acquiring interactive music; that is, music that can be manipulated: arranged, transposed, modified, reformatted, etc. in both symbolic and audio formats. This is a real need for preparing performances, studying music, analysing music, learning instruments, etc., and an absolute real need for blind people which cannot use traditional media. This is presently not possible since music is only distributed as music sheets or audio files.



WEDELMUSIC is an innovative idea for allowing the distribution of interactive music via Internet.
    This will be possible thanks to the definition and implementation of
  • a unified model for distributing music in its several forms (audio, symbolic and image),
  • reliable mechanisms for protecting music based on watermark,

To receive music in symbolic format also allows to commercially exploit new functionalities for music consumers and, thus, it allows the opening of a new market for several specific applications.


The scientific and technological objectives are:

  • to make possible the distribution of interactive music via internet considering audio, symbolic and image formats. These formats will be integrated with each other. The integration will allow, for instance, the distribution of symbolic music with several audio versions, the distribution of images, the distribution of images with the related audio file, the execution of music for producing audio recorded and/or provided with the music, etc. For audio, symbolic and image, specific protection mechanisms and algorithms will be defined. This will make possible the exploitation of new functionalities for libraries, music schools, publishers, theatres, and will open a new market for a large set of new products. For instance: it will be possible to arrange, transpose, modify, reformat, etc., music protecting it without violating rights. The integration will be obtained by defining a new model for coding music in unified manner (audio, images and symbolic) that places the basis for becoming a standard for distributing music via Internet. It will overcome the problems (lack of formalism in defining symbol relationships, lack of interactivity) of classical formats for music notations: NIFF, SMDL, SCORE, FINALE, SIBELIUS, DARMS, MIDI, XML, etc. It will be expandable, flexible, portable in any platforms, considering all aspects that could be strongly useful for modelling music in the future multimedia applications.
  • to define and validate reliable mechanisms based on watermark, encryption and the NV-ACL (Neutral Version - Additional Command Lists) of MOODS project. These will be used for protecting music in audio, symbolic and image formats, thus reducing risks of the inappropriate music distribution resulting in copyright violations. The project will set up security mechanisms for protecting music in audio, image and symbolic formats. For the protection of music sheets specific algorithms for introducing watermarks in the images of music sheets will be studied and implemented. The watermark can be used by the publishers to demonstrate and prove their intellectual property. Similar algorithms will be also defined for the printing of music sheets with hidden watermarks directly inserted by from the computer. Specific algorithms for the insertion of watermark in audio files will be developed. This is strongly needed for supporting the first objective and will be also useful in several other applications in which the music in its several forms is distributed by means of several media. The real power of the effective protection mechanisms is the complexity of the algorithms and the intrinsic linkage with a secret (owned be the copyright holder). This allows to publish the algorithms and extend them to public analysis with no degradation of security. The protection algorithms will be studied and development with this aim. Incorporated encryption algorithms will be so computationally expensive that the decryption to look for the key with an exhaustive algorithm will be quite impossible for a time (in terms of years) comparable to that of copyright coverage.
  • to make possible the exploitation of several new functionalities with the adoption of music in symbolic format for libraries, music schools: music analysis, educational manipulation of music, etc.; thus, it allows the opening of a new market for several specific applications. The libraries could play the role of music distributors. The availability of symbolic music will be the basis for using tools for manipulating music in theatres, music schools, libraries and orchestras, in general. This is mandatory for many publishers and for providing new services to citizens. This will also allow the simplification of the day by day life.
  • to provide support and tools for distributing and providing music to impaired (speech music, Braille Music) and sighted people in a unified manner via libraries and/or music schools. These tools will be produced for validating the model, the language and the protection mechanisms that will be defined. For the complexity of the music distribution system and to study new services, the implementation of specific tools will be mandatory for verifying the defined models and language. These solutions will reduce drastically the cost of Braille music of at least 5 times.
  • to validate and test of a couple of WEDELMUSIC Servers in the real world and to assess the benefits obtained during the validation phase. This will allow to verify the effective value of the model and solutions that will be proposed in the research phases of the project against the real adoption of the model in real environment. To this end, some tools will be implemented.
  • to disseminate and promote the benefits of the new solutions proposed by installing some WEDELMUSIC servers with the support and the validation of publishers, music schools and libraries. This will be performed by means of a couple of workshops and a dissemination phase in which the model and tools will be presented and distributed for free. To these workshops representative libraries, music schools and publishers will be invited.
  • To define a detailed exploitation plan for the results that will be achieved. This will be produced in a deliverable.
  • to reduce the costs for delivering music scores as a substitute of the paper; thus, a reduction of the environmental costs for distributing music. This has also a strong impact on environmental aspects since the cost reduction will be mainly due to the reduction of the paper used.
