An Experiment about Estimating the Number of Instruments in Polyphonic Music: A Comparison Between Internet and Laboratory Results
نویسندگان
چکیده
Internet experiments in the fields of music perception and music information retrieval are becoming more and more popular. However, not many Internet experiments are compared to laboratory experiments, the consequence being that the effect of the uncontrolled Internet environment on the results is unknown. In this paper the results of an Internet experiment with 1168 participants are compared to those of the same experiment with 62 participants but previously conducted in a controlled environment. The comparison of the Internet and laboratory results enabled us to make a point on whether the Internet can be used for our experiment procedure. The experiment aimed to investigate the listeners ability to correctly estimate the number of instruments being played back in a given excerpt of music. The participants listened to twelve short classical and pop music excerpts each composed using one to six instruments. For each music excerpt the participants were asked how many instruments they could hear and how certain they were about their estimation.

Assessing Top-Down and Bottom-Up Contributions to Auditory Stream Segregation and Integration With Polyphonic Music
Polyphonic music listening well exemplifies processes typically involved in daily auditory scene analysis situations, relying on an interactive interplay between bottom-up and top-down processes. Most studies investigating scene analysis have used elementary auditory scenes, however real-world scene analysis is far more complex. In particular, music, contrary to most other natural auditory scen...

This research can be considered as one of the studies that seek to explore, in an argumentative way, subtle and solid philosophical concepts in the field of art. The paper provides an analysis of the concept of “extension” in music as one of the most thought-provoking philosophical concepts. The analysis is carried out by interpreting Ibn-Sina’s special conception of musical extension to answer...
متن کاملDecoding auditory attention to instruments in polyphonic music using single-trial EEG classification.
OBJECTIVE Polyphonic music (music consisting of several instruments playing in parallel) is an intuitive way of embedding multiple information streams. The different instruments in a musical piece form concurrent information streams that seamlessly integrate into a coherent and hedonistically appealing entity. Here, we explore polyphonic music as a novel stimulation approach for use in a brain-...
متن کاملA Robust Retrieval System of Polyphonic Music Based on Comparison of Chord Sequences
Retrieval systems for polyphonic music rely on the automatic estimation of the similarity between two musical pieces. In the case of symbolic music, existing systems consider a monophonic reduction based on melody or propose algorithms with high complexity. In this paper, a new approach is presented. Musical pieces are represented as a sequence of chords estimated from groups of notes sounding ...

Recently, numerous successful approaches have been developed for instrument recognition in monophonic sounds. Unfortunately, none of them can be successfully applied to polyphonic sounds. Identification of music instruments in polyphonic sounds is still difficult and challenging. This has stimulated a number of research projects on music sound separation and new features development for content...
