Subjects listened to a standard six-tone melody, followed by a comparison melody. The comparison melody was always transposed up four semitones from the standard, and this transposition was either exact or it was inexact while maintaining contour. Subjects judged whether or not the comparison melody formed an exact transposition of the standard. It was found that repetition of the standard melo...

This extended abstract is for the “Audio Melody Extraction” contest of MIREX2009. We describe an algorithm that estimates the melody line from a music audio signal. The algorithm is comprised of two stages: melodic component enhancement and melody line tracking. Only a few researchers used this approach because of difficulties of the melody enhancement. Our enhancement algorithm focuses on temp...

BACKGROUND Transannular patch (TAP) repair of tetralogy of Fallot often results in significant right ventricular outflow tract (RVOT) dilation and distortion. We hypothesized that insertion of Melody valves into the proximal right and left branch pulmonary arteries (PAs) would reduce pulmonary regurgitation fraction (PRF) in an ovine model of pulmonary insufficiency and dilated RVOT. METHODS ...

This paper considers a melody extraction algorithm that estimates the melody in polyphonic audio using the harmonic coded structure (HCS) to model melody in the minimum mean-square-error (MMSE) sense. The HCS is harmonically modulated sinusoids with the amplitudes defined by a set of codewords. The considered algorithm performs melody extraction in two steps: i) pitch-candidate estimation and i...

This paper describes a melody morphing method that generates an intermediate melody between a melody and another melody with a systematic order according to a certain numerical measure. Conventional music sequence software only operates on the surface structure of music, such as its notes and rests. The time-span tree, which is acquired from the music surface by using a music theory called GTTM...

A melody recognition system with a voice-only user interface is presented in this paper. By integrating speech recognition and melody recognition technology we have built an end-to-end melody retrieval system that allows a users to do voice controlled melodic queries and melody generation using a dial-in service with a mobile phone.

This paper considers the proposed algorithm submitted to the Music Information Retrieval Evaluation eXchange (MIREX) 2010 “Audio Melody Extraction” task. The proposed melody extraction algorithm can be divided into three steps: (1) a spectral analysis using a variable length window, (2) a pitch candidate estimation, and (3) a pitch sequence identification. In the first step, the short-time Four...

A melody-based retrieval of music, which is one type of the content-based retrieval, is proposed in the paper. Every fragment of a melody is represented as an appropriate N-dimensional vector, called a feature vector. A feature vector consists of values corresponding to intervals and rhythm of a melody. Depending on the distance between every fragment of a melody in the music database to the en...

The purpose of this study was to investigate the perceived similarity between a melody and the exact and inexact transpositions of that melody. Exact transpositions, which preserve the interval structure of the original melody, were formed by manipulating the variables key-distance and pitch-distance. Inexact transpositions, having a different interval structure than the original melody, were c...
