    <subfield code="a">&lt;p&gt;The &lt;strong&gt;Synth-salience Choral Set&lt;/strong&gt; (SSCS) is a publicly available dataset for voice assignment based on pitch salience.&amp;nbsp;&lt;/p&gt;

&lt;p&gt;The dataset was created to support research on voice assignment based on pitch salience.&amp;nbsp;By definition, an &amp;ldquo;ideal&amp;rdquo; pitch salience representation of a music recording is zero everywhere where there is no perceptible pitch, and has a positive value that reflects the pitches&amp;rsquo; perceived energy at the frequency bins of the corresponding F0 values. In practice, for a normalized synthetic pitch salience function we assume a value equal to the maximum energy (salience), i. e., 1, in the time-frequency bins that correspond to the notes present in a song, and 0 elsewhere. We obtain such a synthetic pitch salience representation directly by processing the digital (MusicXML, MIDI) score of a music piece, using the desired time and frequency quantization, i. e., a time-frequency grid.&amp;nbsp;&lt;/p&gt;

&lt;p&gt;To build the SSCS, we collect scores of four-part (SATB) a cappella choral music from the &lt;a href="https://www.cpdl.org/wiki/index.php/Main_Page"&gt;Choral Public Domain Library (CPDL)&lt;/a&gt;&amp;nbsp;using their API. We assemble a collection of &lt;strong&gt;5381 scores&lt;/strong&gt; in MusicXML format, which we subsequently convert into MIDI files for an easier parsing.&lt;/p&gt;

&lt;p&gt;&lt;br&gt;
Each song in the dataset comprises five CSV files: one with the polyphonic pitch salience representation of the four voices (*_mix.csv) and four additional files with the monophonic pitch salience representation of each voice separately (*_S/A/T/B.csv). In both cases, the asterisk refers to the name of the song, which is shared between all representations from the same song.&lt;br&gt;
Besides the pitch salience files, we provide a metadata CSV file (sscs_metadata.csv) which indicates the associated CPDL URL for each song in the dataset.&amp;nbsp;Note that this dataset contains the input/output features used in the cited&amp;nbsp;study, i.e., salience functions, and not audio files nor scores. However, the accompanying&amp;nbsp;metadata file allows researchers to access the associated open access scores for each example in the dataset.&lt;/p&gt;
