Structured Polyphonic Patterns
نویسندگان
چکیده
This paper presents a new approach to polyphonic music retrieval, based on a structured pattern representation. Polyphonic patterns are formed by joining and layering pattern components into sequences and simultaneities. Pattern components are conjunctions of features which encode event properties or relations with other events. Relations between events that overlap in time but are not simultaneous are supported, enabling patterns to express many of the temporal relations encountered in polyphonic music. The approach also provides a mechanism for defining new features. It is illustrated and evaluated by querying for three musicological patterns in a corpus of 185 chorale harmonizations by J.S.Bach.

Temporal Patterns in Polyphony
This paper formally characterizes the expressiveness of three approaches for polyphonic pattern representation and matching: R (relational patterns); H (Humdrum); and SPP (Structured Polyphonic Patterns). Relational networks have the highest expressiveness but H and SPP admit faster matching algorithms. It is shown how H and SPP can be cast as different restrictions of R, both providing an expr...
متن کاملPosition Indexing of Adjacent and Concurrent N-Grams for Polyphonic Music Retrieval
In this paper we examine the retrieval performance of adjacent and concurrent n-grams generated from polyphonic music data. We deploy a method to index polyphonic music using a word position indexer with the n-gram approach. Using all possible combinations of monophonic sequences from polyphonic music data, “overlaying” word locations within a document are obtained, such as needed with polyphon...
متن کاملTree structured and combined methods for comparing metered polyphonic music
Identifying copies or different versions of a same musical work is a focal problem in maintaining large music databases. In this paper we introduce novel ideas and methods that are applicable to metered, symbolically encoded polyphonic music. We show how to represent and compare polyphonic music using a tree structure. Moreover, we put for trial various comparison methods and observe whether be...
متن کاملMelodic Pattern Segmentation of Polyphonic Music as a Set Partitioning Problem
In polyphonic music, melodic patterns (motifs) are frequently imitated or repeated, and transformed versions of motifs such as inversion, retrograde, augmentations, diminutions often appear. Assuming that economical efficiency of reusing motifs is a fundamental principle of polyphonic music, we propose a new method of analyzing a polyphonic piece that economically divides it into a small number...
متن کاملEfficient Learning of Harmonic Priors for Pitch Detection in Polyphonic Music
Automatic music transcription (AMT) aims to infer a latent symbolic representation of a piece of music (piano-roll), given a corresponding observed audio recording. Transcribing polyphonic music (when multiple notes are played simultaneously) is a challenging problem, due to highly structured overlapping between harmonics. We study whether the introduction of physically inspired Gaussian proces...
