The Zentralbibliothek Zurich and several other Libraries in Switzerland own large numbers of music scores. Several of these scores are accessible via the digital platforms e-manuscripta and e-rara. But what if you want to hear the music instead of just seeing the score sheets? We would like to make digitised music scores deposited on e-manuscripta and e-rara audible, using OMR and notational software. Our overall goal would be to develop a workflow resulting in audio files. Such a workflow would at any rate include manual steps. Rather than developing a fully automated pipeline, this little explorative study is an attempt to find out about the potentials of OMR in a cultural heritage context, possibly making written music more accessible.
