About

This data set has the following characteristics:
• the list of works has been manually created and annotated (inc. birth dates, death dates, video links, start time, tonalities... basically all fields except the IDs);
• the selection is a diverse catalogue of famous and less famous classical music works;
• the five interpretations per work are all from different recordings;
• each recording contains a live (recorded live) and a start_at manual annotations (skipping applauses, instrument tuning or other artefacts);
• each work contains descriptive metadata such as opus numbers, detailed titles, composer names and dates, tonality and a link to Wikipedia.

Each work, or clique, is mostly recorded with the same instrumentation despite rare examples such as Jean-Philippe Rameau: Suite en sol in G major "Nouvelle suite" - 6. Les sauvages played either by a harpsichord or a piano; and the same tonality or very close ones such as in Ludwig Van Beethoven: Symphony No.5 in C minor, Op. 67 in a range of about 1 tone away from C due to historical and artistic considerations.

Here is an example of a work in this dataset.

This dataset contains 100 of such works. Here are a detailed field description:
• rdb_id_piece (100/100): This is the unique piece ID of this work in Rondo DB. If you prefix it with https://www.rondodb.com/piece/ you will reach its official page on Rondo DB.
• name (100/100): The raw name of the piece. As most of classical pieces don't have titles, this is in general the form of the piece, like here: "Symphony".
• number (37/100): Applicable to pieces with numbering. Only 32 of them in this dataset. Otherwise the field is absent.
• piece_full_name (100/100): Generally accepted name for the given piece. Contains catalog information, subname and tonality.
• piece_full_name_with_composer (100/100): Same as piece_full_name but prefixed with composer first name and last name and a semi column.
• catalog_number (79/100): This is the full information of how this piece is generally catalogued. Despite the name of the field, this is not a number but a textual information, such as "Op. 37"
• tonality (57/100): A full tonality (key and mode) of the given piece. Flats and sharps are writen like "E-flat" or "C-sharp".
• composition_year (91/100): The year on four digit of the composition of this piece.
• wikipedia_url (82/100): The full URL of the English Wikipedia page describing this work.
• rdb_id_movement (26/100): The ID of a movement on Rondo DB. By prefixing this ID with URL https://www.rondodb.com/movement/ you will go to the unique movement page on Rondo DB. A "movement" can also be a "part" in a piece edited with several parts, like a book of preludes, études, or arias in an opera.
• movement_full_name (26/100): The name of a movement, which can contain the number of the movement, like in "5. Andaluza". The movement name is part of the piece_full_name and piece_full_name_with_composer as described above.

composer (100/100) is a nested object and contains the following fields:
• rdb_id_people (100/100): The Rondo DB ID of this composer. By prefixing this ID with URL https://www.rondodb.com/people/ you will go to the unique composer page on Rondo DB.
• birth_date (100/100): The date of birth in format YYYY-MM-DD.
• death_date (100/100): The date of death in format YYYY-MM-DD.

recordings (100/100) contains a like of five recording objects. Each recording contains the following fields:
• is_live (500/500) indicates if the recording has been performed live or not. When recorded live, it indicates that it can contain applauses before/after the recording, tuning orchestra, noises during the performances...
• start_at (500/500) the time where the piece is actually starting at, in seconds. Will roughly starts in less than a second after this point. The instruction given to the annotator was: "place the cursor just before the piece actually starts".
• url (500/500) the full URL of the Youtube video. At the time of the creation of the dataset, all recording were publicly available.
