What is it about?
In tonal music, particularly Classical music, the music gravitates around a musical "key". The key often changes throughout the piece. This is sometimes referred to in music theory as either a "modulation" or "tonicization". The distinction is often blurry. In this paper, we discuss these terms from a computational perspective.

Why is it important?
The music-theoretical notions of "modulation" and "tonicization" are rarely discussed in Music Information Retrieval and computational work. However, these terms are crucial for defining the classification tasks of machine learning models for music. Tackling these issues from a musical and computational point of view is crucial to increase the value of computational models.
Perspectives
It might be that some "local-key-estimation" algorithms are more inclined to be "tonicization" finders than "modulation" finders. Quantifying these tendencies might provide meaningful insights to computational musicologists.
