 - Number of Sections (NS): controls the number of sections in the entire melody. This can be used to create a sense of structure and coherence within the melody, as different sections can be used to create musical themes or motifs. It counts on several symbols that are commonly used in ABC notation and can be used to represent section boundaries: ***\[|***, ***||***, ***|\]***, ***|:***, ***::***, and ***:|***.
 - Edit Distance Similarity (EDS): controls the similarity level between the current section and a previous section in the melody. 
 
-To ensure consistency and standardization among the ABC tunes in the dataset, we first converted them all into MusicXML format and then re-converted them back into ABC notation. In order to focus solely on the musical content, we removed any natural language elements (such as titles, composers, and lyrics) and unnecessary information (such as reference numbers and sources).
