Lecture 21 Flashcards
What is pitch?
Quality of tones that range from high to low, often organized on a musical scale (associated with melodies)
What is a melody?
the experience of a sequence of pitches as belonging together
What is timbre?
Refers to various qualities of sound that differ across musical instruments
What is harmony/consonance/dissonance?
Qualities of sound (positive or
negative) that emerge when multiple pitches are played together
What is rhythm?
a temporal structure created by the inter-onset interval of
notes (the time between the onset of notes, not the duration of those notes)
Which areas of the brain are activated by music?
- Amygdala and nucleus acumbens (emotion)
- The hippocampus (memory)
- Cerebellum and motor cortex (movement)
- Visual cortex (while reading music, watching performances)
- Sensory cortex (touch feedback while playing instruments)
- Prefrontal cortex (modelling the structure of a piece of music, generation expectations,
etc.)
What is the beat?
Equally spaced intervals of time, which occur when there are no notes
* This creates a framework for other components of music to ‘fit into’ (notes,
rhythm, etc.)
* When people tap their foot, they (typically) tap on the beat
Describe Grahn & Rowe study
Grahn and Rowe (2009) listened to either ‘beat’ or ‘non- beat’ stimuli (beat stimuli included shorter notes that fell directly on the beat, increasing awareness of it)
- Found that basal ganglia activity was greater for beat
stimuli, as compared to non-beat stimuli
Describe Chen study
- Chen et al. (2008) found activity in the premotor cortex increased across three
conditions that involving listening to beat stimuli:
1. Tapping along
2. Listening with the intention of tapping along later
3. Passive listening - Activity increased the most in the ‘tapping along’ condition (followed by the
listening with the intention of tapping along later) - As with the last study, demonstrates a close link between the beat and movement
Describe meter
the organization of beats into bars or measures (often accenting the
first beat in each bar)
Describe metrical structure
can be created by accentuating in various ways (playing that note louder, with a stronger attack, etc.
What is a duple meter?
1234, 1234, 1234, 1234
12, 12, 12, 12
What is a triple meter?
123, 123, 123, 123
