Chapter 6 Flashcards
rhythm
time pattern created by notes as music unfolds over time
- onsets determine rhythm, not note durations
- based on relative time, stay constant even when tempo changes proving its based on relative time
tempo
the rate at which music unfolds
serial ratio
the ratio formed by 2 adjacent time spans
categorical perception
a tendency to treat a range of values along a physical continuum as if they were the same until one reaches a point at which the percept abruptly changes
grouping occurs
0-200 ms
300-infinity beats per minute
discontinuity occurs
1000-1200 ms
60-50 beats per minute
meter
number of beats in a bar
two components of meter
- beat
2. cyclical nature of meter
entrainment
one rhythmic pattern acheives and maintains synchrony with another pattern
- people time their attention to events in the world by adapting an internal rhythm
clock counter model
tone onsets trigger the initiation of a counting process
- clock ticks while a subconscious process counts them
- clock ticks like spontaneous neural spikes, which could be the neural mechanism
when a participant imagines regularly tapping the areas of the brain activated are
sensorimotor and parietal cortices that are equivalent in rate to the imagined rhythm
simpler rhythms brain activity was in
motor cortex and cerebellum
when participants retained complex rhythms brain activity was in
prefrontal cortex as well as cerebellum and motor cortex
