In the Interpreter window, users may load a mensural MEI file from their local computer or from a URL, and then select ‘Run’ in the top menu bar to begin analysis. In order to inspect the interpreter’s analysis, users should click on a note within the rendered music in order to display this information in a side-window to the left of the music notation. Note-to-note navigation within bar lines may be carried out using the ← and → keys.
Modified notes will be highlighted by a color code in interpreter mode:
If necessary, users may wish to adjust the interpreter’s results. This may be achieved in the left window, under ‘Interpreter Modification’, by adding or changing quality or ‘num/numbase’, ‘rule’, and ‘duration in minims’. The quality of a note is added only in cases of ambiguity (following the current mensuration). Please do not use, for example, “perfecta” for already-perfect notes. To remove an erroneously set quality, choose “none”. While quality is used for standard imperfection and alteration, num/numbase is used for cases of partial imperfection. For example, should a user wish to change the absolute duration of a longa from six semibreves to five semibreves, num should be changed to ‘6’, and numbase to ‘5’. Users may save their feedback by adding their name and initials before selecting ‘Save’ in the (otherwise it breaks). The mensurally coherent blocks detected may be inspected in the ‘Blocks’ window.
A line-by-line explanation of the logical procedures carried out by MeRIT is available in the ‘Rules’ section.
The interpretation produced by MeRIT is written in standards-compliant MEI, including details of the rules being applied at each point and a fine-grained metrical analysis. This interpreted MEI may be downloaded using the ‘MEI’ button in the top menu bar.
MeRIT is an output of Interpreting the Mensural Notation of Music (2017–2022), an AHRC-funded research project hosted at the Royal Birmingham Conservatoire. For more information about the project and its team, funding, and outputs, please see the ‘about’ menu at the top of this page.
