The goal of the site is to allow users to find and submit patterns found in music.

A musical pattern or motive is defined as a short musical idea, a salient recurring figure, musical fragment, or succession of notes that has some special importance in or is characteristic of a composition. It shouldn’t be longer than a musical phrase. If you find a motive that is similar to another (or multiple versions of a motive), please annotate the repetitions as well. Exact repetitions of a pattern can also be annotated automatically. You can mark different levels of importance of a pattern by rating it from 1 (not as relevant) to 3 (highly relevant). The default value of representativeness will be 0 if you do not give a rating.

To begin, click on a note to mark it as the start of a pattern. The starting note will be coloured blue. Next, click on another note to mark the end of that pattern. All of the notes between the start and the end will be coloured red, thus representing a marked pattern. To mark multiple patterns simply repeat the process.

Each pattern also includes an ID field (top left corner), which can be used to change the ID of a pattern. To denote multiple pattern occurrences, the ID of a repeated pattern can be changed to match the ID of the original pattern. Alternatively, exact repetitions of a pattern can also be annotated automatically. By pressing the A button on a pattern (bottom right corner) all repetitions of the selected pattern will be automatically marked. Other occurrences of the pattern other than exact repetitions must be added manually.

To delete an UNFINISHED pattern click on its starting note, which is coloured blue.

To delete an already FINISHED pattern press on the X button, which can be found in the right corner of each pattern.
