The final results reported are the average f1-score of the three metrics. We will compute the f1-score of COnPOff, COnP and COn on each song. However, COnP only requires the two notes to satisfy (1) and (2), while COn only requires the two notes to satisfy (1). Two notes should satisfy all three conditions above to be considered as “correctly transcribed” in COnPOff metric. The offset difference is less than the threshold defined by max(50ms, 0.2* duration of groundtruth note) in this competition. The pitch difference is less than the threshold (50 cents in this competition).ģ. The onset difference is less than the threshold (100ms in this competition).Ģ. Three rules are utilized to determine if two notes are matched with each other:ġ. Each note in groundtruth can only be matched with one transcribed note, and vice versa. These metrics compute the maximum number of groundtruth notes that are corrected transcribed. We will use Python package “mir_eval” to evaluate the accuracy of a transcription by computing COnPOff, COnP and COn metrics described in. We strongly suggest participants to use this dataset as training set (if your algorithm is data-driven), since the property of Cmedia training set is close to Cmedia hidden set. We will release 100 of them as the open set for training/validation (training set), and use the other 100 as the hidden set for test. This dataset consists of 200 Youtube links of pop songs (most of them are Chinese songs), together with their groundtruth files of vocal transcription. 3, 5, 8, 10, 23, and 66) with multiple singers (the melody part is not monophonic), the remaining 94 songs can be used for this task. The database is available at, and the annotations are available at. RWC-MDB-P consists of 100 songs and annotations in MIDI format (AIST annotation). We can use the “Popular Music Database” part of RWC database for this task. RWC Music Database : Popular Music (RWC-MDB-P) Two datasets can be used to construct and evaluate a model for singing transcription: Therefore, to make the name more specific, we call the task that “transcribing polyphonic music that contains only monophonic vocal into notes” as singing transcription from polyphonic music. Some researches regard this term as the task of “transcribing polyphonic music into notes”, but other researches seems to regard this term as the task of “transcribing monophonic signals without accompaniment into notes”, since both of them created monophonic datasets (without accompaniments) for “automatic singing transcription”. This task is different from “audio melody extraction”, since the target of melody extraction is to determine pitch for each frame, while singing transcription is aimed to determine notes of vocal part in music.īesides, it's worth noting that the definition of “singing transcription” is not quite specific. Algorithms that directly perform singing transcription on mixed audio are also welcome. However, this is not a necessary part of a singing transcription algorithm. Therefore, to deal with this task, algorithms that separate vocal part from audio may be considered as a preprocessing step. The vocal part is monophonic, but the accompaniments are not.

The input of this task is a music recording (mostly pop music) that contains a vocal and some accompaniments, and the output is a series of notes. The goal of this task is to transcribe the vocal part of polyphonic music into a series of notes, each note is denoted by three numbers, onset, offset and the score pitch. 2.1 RWC Music Database : Popular Music (RWC-MDB-P).This point-against-point conception is opposed to "successive composition", where voices were written in an order with each new voice fitting into the whole so far constructed, which was previously assumed.

In all cases the conception was probably what Margaret Bent calls "dyadic counterpoint", with each part being written generally against one other part, with all parts modified if needed in the end. Also, as opposed to the species terminology of counterpoint, polyphony was generally either "pitch-against-pitch" / "point-against-point" or "sustained-pitch" in one part with melismas of varying lengths in another. Baroque forms such as the fugue, which might be called polyphonic, are usually described instead as contrapuntal. Within the context of the Western musical tradition, the term is usually used to refer to music of the late Middle Ages and Renaissance. Polyphony In music, polyphony is a texture consisting of two or more simultaneous lines of independent melody, as opposed to music with just one voice or music with one dominant melodic voice accompanied by chords.
