Even trained musicians have great difficulty detecting deviant melodic patterns under transposition

Evidence

However, when healthy adults are required to detect rare deviant melodic patterns in a sequence of randomly transposed standard patterns they perform close to chance. Musically experienced participants perform better than naïve participants, but even they find the task difficult, despite the fact that musical education includes training in interval recognition. — Dijk, Pim van, Physiology, Psychoacoustics and…, 5260

Categorization

• QUESTION: Why does interval recognition training fail to transfer to this deviant-detection task? What is the mismatch between the trained skill and the experimental demand?
• XREF: Connects to the broader literature on relative pitch being easier in recognition (melodies in different keys) than in discrimination tasks; parallels findings on absolute vs relative pitch and categorical perception.
