Registration for the C at merata 2016 task at MediaEval is now open!

There are 200 questions each year which a participant's system has to answer
automatically. A question is a short string "F4 crotchet in the oboe" and it
comes with a classical music score in MusicXML. The required answer to this
question is a set of one or more passages like this:

[ 3/4, 2, 5:1-5:2 ]
[ 3/4, 2, 29:1-29:2 ]
[ 3/4, 2, 64:3-64:4 ]
[ 3/4, 2, 7:5-7:6 ]

These specify exact places in the score where the oboe is playing a note of a
particular pitch (F4) and length (crotchet). Evaluation of participant runs is
by forms of Precision, Recall and F-Measure which we have devised for the

The long-term aim of C at merata is to deepen our knowledge of computer musicology
by investigating the link between musicological texts and the music itself.

Now in its third year, the task suits musicologists who have a knowledge of
programming and computer scientists who have a knowledge of Western classical
music. In particular, if you are a Python programmer we have tools which can
help you get started.

Each year, the questions become more complicated. This year, they are being
derived from various sources including music theory exam papers, musicological
text books and Grove's Dictionary of Music and Musicians (Grove Online).
