“…We might hypothesize that, given a collection of pitches in shortterm memory, we are able to mentally ''calculate'' or ''feel'' the sensory fit of any current pitch or chord each time it occurs. However, even if bottom-up processes play an important role, it would be implausible to dismiss the impact of long-term memory (the importance of long-term memory has been established in numerous music perception experiments such as Franc猫s, 1988;Lynch, Eilers, Oller, & Urbano, 1990;Trehub, Schellenberg, & Kamenetsky, 1999). For instance, it is likely that certain scales (e.g., the diatonic and harmonic minor) are so commonly used that we learn where the best fitting chords are without having to mentally assess their sensory fit each time.…”
