Audiovisual recordings of performances, rehearsals and practical experiments are useful teaching materials for professional training in the field of opera and can be used in any training modality, in presence, at a distance, partly in presence and partly at a distance. The Virtual Stage project partners carried out extensive experimentation both to collect experiences and data to support the development of new training methodologies and practices and to pilot the project results. This is a collection of demos that forms an integral part of the project results and illustrates the applications of digital technologies in training artists on specific repertoires. Through the Virtual Stage training resource archive these materials are made available to the opera training communities for free educational use.
