Listening to music
- Music listening is sequential and involves multidimensional processing.
- We hear streams of sequential data
- The streams suggest hierarchical relationships both internally and
amongst parallel dimensional streams
- Hierarchies are perceived by a process of comparison and reduction
- These relationships occur simultaneaously at differing scopes from
local to global
- The sequences are information rich often involving multidimensional
- These dimensions can be independent or they can influence other dimensions
- Dimensions can be mutually influential
Contexts and prediction
- Listening to music involves context building
- Contexts involve memory
- Memory has a dynamic nature of its own - it can be short or long
term, and can decay at variable rates and over varying time spans.
- Memory conditions how we understand the present and, in turn, how
we predict the future
- Contexts are used to predct the next elements in the sequence.
The temporal nature of music complicates the issue...
- Although musical information is sequential, listening associates
a temporal dimension to the sequence
- A listener notonly predicts what will occur next, but also
when it will occur
- Simple periodic patterns are used by listeners to organize the temporal
- These metric groups direct the prediction of when
- The sequential event influences the preference of a given metric
organization over others. This means that metric organization and prediction
are mutually influential.
