The concept of similarity is central to perception. It underlies processes such as object recognition, comparison, memory retrieval, classification, problem solving, and inductive reasoning, which are crucial to much of human cognitive processing. In the domain of music, similarity plays a vital role in perceptual and cognitive processes such as grouping, segmentation, musical variation, genre recognition, and expectancy. Furthermore, memory and schematization processes in real-time listening rely on the recognition of small figures, or cues, which again is based on the notion of similarity (Deliège, 2001). Therefore, it is evident that understanding of the basic processes underlying perception of musical similarity is necessary for acquiring a deeper comprehension of music perception in general.
The articles published in this issue, although dealing with the common topic of similarity, comprise a diversity of different approaches and methodologies, and to provide a synopsis of them is an arduous task. We asked Geraint Wiggins to take on this job, and he was brave enough to agree. In his article, he compares the different approaches presented in this issue, and provides a summary of them in particular in light of crucial issues of modeling such as knowledge and data representation as well as the distinction between explanatory and descriptive models.

How similar is similar?
Cambouropoulos, Emilios (2009)In the first part of the paper a theoretical discussion is presented regarding the fundamental concept of similarity and its relation to cue abstraction and categorisation. It is maintained that similarity is by definition ... -
Modelling experts notions of melodic similarity
Müllensiefen, Daniel; Frieler, Klaus (2007)In this article we show that a subgroup of music experts has a reliable and consistent notion of melodic similarity, and that this notion can be measured with satisfactory precision. Our measurements enable us to model ... -
Themes as prototypes: Similarity judgments and categorization tasks in musical contexts
Ziv, Naomi; Eitan, Zohar (2007)Similarity judgments and corresponding categorizations often differ, as the former does not predict the latter (Keil, 1989). Prototype-based models suggest that categorization emphasizes features which distinguish ... -
Alien plants and recipient habitats in the Mediterranean Basin: How similar they are?
Arianoutsou, Margarita; Delipetrou, Pinelopi; Celesti-Grapow, Laura; Basnou, Corina; Bazos, Ioannis; Kokkoris, Yannis; Blasi, Carlo; Vilá, Monsterrat (Open Science Centre, University of Jyväskylä, 2018)Biological invasions have become one of the most critical issues related to global change. The aim of this work was to investigate alien plant species invasion levels in different habitats and alien species traits by ...
