Goals and Objectives

As part of the European project Polifonia (H2020 grant agreement N. 101004746) Tonalities embraces the open linked data paradigm to reference large corpora of music made available in digital score libraries and to explore them analytically through a quantitative-qualitative approach. This approach consists of modelling different theories – historical or contemporary, specific or general – and applying them to musical works through a dedicated interface combining machine learning and human annotation

The collaborative annotation interface for music analysis that constitutes the core of Tonalities addresses the following challenges:

  • Selecting different models, corresponding to different theoretical and analytical viewpoints.
  • Selecting every item on the score (single notes, groups of notes, verticalities, etc.) at any level of granularity.
  • Creating arbitrary selection trees through nested selections, editing a selection or adding/removing elements (including other selections).
  • Associating concepts derived from the models with these analytical elements.
  • Commenting on the analytical annotations.
  • Comparing the annotations made on the same score either by different users or on the basis of different models.

To this end, Tonalities builds on the laboratory’s data model, developed and implemented in the SHERLOCK project – a web platform for collaborative knowledge-creation processes – and provides a dynamic web application for creating, editing and deleting RDF data via a dedicated API.

  • We offer an easy-to-use and centralized programmatic interface for creating CIDOC-CRM-based RDF data relating du music theory and analysis.
  • We ensure that the data is standardized and fits to the SHERLOCK model developed at the IReMus. 
  • We manage the access rights through the ORCID third party authentication service: all analytical annotations are signed (ORCID ID), resources can only be edited by their authors, all contributions can be retrieved through ORCID IDs
  • We encourage other web applications from other laboratories to use the service provided.

On this basis, it becomes possible to grasp how distinct theoretical viewpoints bring to light different – sometimes conflicting – musical properties; confront different analytical interpretations; look “inside” both theories and works; understand how both evolve in time in relation to each other; and, ultimately, provide reasoned, documented, and authored analyses. In addition to external score libraries (Josquin Research Project, CRIM, Measuring Polyphony, Gesualdo Online, The Lost Voices Project), Tonalities is relying on the NEUMA score library developed at the IReMus in collaboration with the CNAM.

The opinion of the scientific community matters to us. If you want to evaluate the software and influence its development, please fill out this questionnaire (5 minutes):

Improvements implemented in the v2 of Tonalities' interface 

A first evaluation campaign addressed to our stakeholders made emerge some general problems, critics/suggestions on ergonomics, and corrections on the terminology adopted in the first version of the interface:

  • the process of selection requires too many passages and manipulations;
  • the process of annotation is time-consuming;
  • a list of shortcuts for all the typologies of selection should be added;
  • a system of pop-ups could be adopted to manage the classes and properties of the theoretical models;
  • to implement an automatic system for generating some basic analysis (e.g. to track all the dissonances);
  • ergonomics and intuitiveness/clarity need to be improved;
  • the hotspot of the elements in the score must be enlarged in order to improve the selection options;
  • some terminology needs to be corrected. 

Improvements have, therefore, been made in the perspective of reducing clutter. Another suggestion was about the intervention/collaboration of an expert in Web ergonomics. A general strategy to adopt have been to study the functionalities and the options already available in other similar music web-services, in order to meet the end user’s habits and familiar gestures. An extra effort have also been made in order to reduce the time-consuming of the music analytical process on the screen. This will potentially be lesser than the same process conducted in the traditional way. Another important aspect we took into account was to give the possibility to the end user to suggest a personal and adapted analytical scenario, going beyond the possibilities currently offered by the Interface.
