DATA ANALYSIS PHASE
Select a repertory (one composer, one genre)
Encode several pieces
Parse them into five elements of musical grammar
… Statements
… Preparations
… Extensions
… Antecedents
… Consequents
Discover and store “signatures” (identify “earmarks”)

SIGNATURES IN THE SPEAC GRAMMAR
Are relatively short (2-5 events)
Are shorter than themes
Are stored with approach and departure info
Are described by intervallic relationships
Are not described by key or mode

COMPOSING NEW WORKS
User selects a composer
User selects a genre
User selects a key and mode
User selects a meter
Emmy generates one (or many) new work(s)
User discards what he does not want

WAYS OF EXPERIENCING EMMY
Listening to MIDI performances
Listening to live performances
Viewing the notated music
Performing the music

REACTIONS TO EMI
From MIDI files
“mechanical”
Too fast
Too slow
Too soft
Too loud
Not human
From live concerts
That’s by a computer?

COMPUTER MODELS OF MUSICAL CREATIVITY
Initiates process of signature capture from interactive user responses
Evolves its own lexicons
Models broader processes of grammatically-founded processes including
… Speech
… Poetry
… Lyrics

HIDDEN STRUCTURE
Takes comprehensive view of 20th-century analytical concepts
Makes them available for compositional algorithms
… Post-tonal music
… Generative algorithms
