TL;DR: Contrary to common practice, this work proposes to record and utilize sound samples containing not one, but short sequences of pitches, so that natural pitch transitions are preserved and phrases appear to be much smoother, despite using very limited set of performance rules.
Abstract: Sound synthesizers are a natural element of a musician's toolset. In music arrangement, samplers can often produce satisfactory results, but it requires a combination of manual and automatic methods that may be arduous at times. Concatenative Sound Synthesis reproduces many of natural performance- and expression-related nuances- but at a cost of high demand for processing power. Here, another method of musical phrase synthesis aimed at music arrangement is presented that addresses these and other related issues. Contrary to common practice, we propose to record and utilize sound samples containing not one, but short sequences of pitches. In effect, natural pitch transitions are preserved and phrases appear to be much smoother, despite using very limited set of performance rules. The proof-of-concept implementation of the proposed method is discussed in detail along with attempts at optimizing the final sound effects, based on auditory tests. The limitations and future applications of the synthesizer are also discussed.

TL;DR: A comparative study of music features derived from audio recordings, i.e. the same music pieces but representing different music genres, excerpts performed by different musicians, and songs performed by a musician, whose style evolved over time is presented.
Abstract: The paper presents a comparative study of music features derived from audio recordings, i.e. the same music pieces but representing different music genres, excerpts performed by different musicians, and songs performed by a musician, whose style evolved over time. Firstly, the origin and the background of the division of music genres were shortly presented. Then, several objective parameters of an audio signal were recalled that have an easy interpretation in the context of perceptual relevance. Within the study parameter values were extracted from music excerpts, gathered and compared to determine to what extent they are similar within the songs of the same performer or samples representing the same piece.

TL;DR: An algorithm is presented that uses the Kalman filter to combine simple phrase structure models with observed differences in pitch within the phrase to refine the phrase model and hence adjust the loudness level and tempo of qualities of the melody line.
Abstract: In this paper, we present an algorithm that uses the Kalman filter to combine simple phrase structure models with observed differences in pitch within the phrase to refine the phrase model and hence adjust the loudness level and tempo of qualities of the melody line. We show how similar adjustments may be made to the accompaniment to introduce expressive attributes to a midi file representation of a score. In the paper, we show that the subjects had some difficulty in distinguishing between the resulting expressive renderings and human performances of the same score.
