Abstract In this thesis the field of Musical Information retrieval was introduced in order to provide the setting for the main subject of the thesis: ´´Instrument Detection in Music”. A spectrogram alike quantity was developed using a Constant Q Transform, to facilitate the investigation of harmonic content of music signals, and to form the basis components used in one of two methods being developed. A classification framework consisting of two methods, namely Sparse Nonnegative Matrix Factor 2 dimensional Deconvolution and reduced Kernel Partial Least Squares, were implemented and applied to Instruments detection. Samples of a philharmonic orchestra were used to construct several test sets, produced in a software sequencer. Experiments showed that the proposed methods are suitable for the task of Instrument Detection in Music.
