A Technique for Regular Expression Style Searching in Polyphonic Music
نویسنده
چکیده
This paper discussed some of the ongoing investigative work on integrating these two systems conducted as part of the NSF/JISC funded OMRAS (Online Music Retrieval and Searching) project into polyphonic searching of music. It describes a simple and efficient “piano-roll” based algorithm for locating a polyphonic query within a large polyphonic text. It then describes ways in which this algorithm can be modified without affecting the performance to allow more freedom in the how a match is made, allowing queries which involve something akin to polyphonic regular expressions to be located in the text.

A Relational Database Approach to Polyphonic Music Search Systems Using Regular Expressions
We present a model for a database of multi-track polyphonic songs searchable via regular expressions and stored in a relational database. The database is a standard off-the-shelf SQL-based relational database management system. The regular expression format used is of our own design, but could be replaced by any equivalent format. Songs are culled from non-analog sources such as MIDI and decomp...
متن کاملPROMS: A Web-based Tool for Searching in Polyphonic Music
PROMS, a computer-music service under development at the University of Bonn, Germany, aims at designing and implementing PROcedures for Music Search. This paper discusses an eÆcient algorithm for searching a music pattern, e.g., a melody or a sequence of chords, in a large database of polyphonic music, given in a score-like format. Our algorithm is a variant of the now classic inverted le index...
متن کاملProblems of music information retrieval in the real world
Although a substantial number of research projects have addressed music information retrieval over the past three decades, the field is still very immature. Few of these projects involve complex (polyphonic) music; methods for evaluation are at a very primitive stage of development; none of the projects tackles the problem of realistically large-scale databases. Many problems to be faced are du...
متن کاملCharacteristics of Polyphonic Music Style and Markov Model of Pitch-Class Intervals
For the purpose of quantitatively characterising polyphonic music styles, we study computational analysis of some traditionally recognised harmonic and melodic features and their statistics. While a direct computational analysis is not easy due to the need for chord and key analysis, a method for statistical analysis is developed based on relations between these features and successions of pitc...
متن کاملStyle Imitation and Chord Invention in Polyphonic Music with Exponential Families
Modeling polyphonic music is a particularly challenging task because of the intricate interplay between melody and harmony. A good model should satisfy three requirements: statistical accuracy (capturing faithfully the statistics of correlations at various ranges, horizontally and vertically), flexibility (coping with arbitrary user constraints), and generalization capacity (inventing new mater...
