MUSICAL INFORMATION RETRIEVAL USING MUSICAL PARAMETERS
Kjell Lemström, Pauli Laine · University of Michigan Library Repository · 1998
The application domain for automatical retrieval of melodic excerpts in musical collections is wide; e.g. it would facilitate the work of music researcher trying to find specific features in music.In this paper we consider several parts of the retrieving process.We present our representation for musical data.This inner representation is converted and established from MIDI-files.For the matching we use a particular encoding (two dimensional relative code), which is formed out of the inner representation.This encoding can be interpreted differently depending on the way the key is given.Furthermore, in the matching phase we use an efficient indexing structure, well-known in string pattern matching, called suffix-trie.
