Hidden principles of improvisation

N-gram Modeling of Tabla Sequences Using Variable-length Hidden Markov Models for Improvisation and Composition

Directed Improvisation

We introduce "directed improvisation," a new paradigm for human-computer interaction (HCI). Users direct computer "characters" with abstract instructions and constraints. The characters improvise behaviors that follow the directions, express their personal styles, and meet other objectives. We illustrate directed improvisation with our current testbed application, a Computer-Animated Improvisat...

Control Improvisation

We formalize and analyze a new automata-theoretic problem termed control improvisation. Given an automaton, the problem is to produce an improviser, a probabilistic algorithm that randomly generates words in its language, subject to two additional constraints: the satisfaction of an admissibility predicate, and the exhibition of a specified amount of randomness. Control improvisation has multip...

improvisation of blues melodies

A computer program has been written which composes blues melodies to fit a given backing chord sequence. The program 1s compri sed of an analysis stage followed by a synthesis stage. The analysis stage takes blues tunes and produces zero, first and second order Markov transition tables coveri ng both pitches and rhythms. In order to capture the rel at ionship between harmony and melody, a set o...

The relation of improvisation in music & Social character of improviser

This research investigates the relation of social practices and behavior of the musician or singer with the quality of his improvisation in the field of music. Using analytic method and field study, it explores the views of two groups of interviewees in the form of two separate statistical communities. The first sample consists of outstanding teachers of music in sixties and nineties which deal...
