“…The polishing of students' minds can be seen as a way to overcome many psychological problems in their growth and lay the foundation for healthy development [17][18]. By providing students with a stage to showcase their individuality, students' desire for communication and expression is well realized, and it also promotes the formation of a healthy campus culture, enabling students to better plan their next academic life according to their developmental needs [19][20]. The influence of good habits on personal development is not only to improve student's quality in a certain aspect but also to promote their regular life and self-discipline.…”

This paper uses an adaptive differential evolution algorithm to handle multiple conflicting optimization objectives by randomly generating uniformly distributed values corresponding to the upper and lower bounds so that the variance vectors are crossed over. A diversity metric measures the degree of uniformity of distribution between solutions, using a pre-given interval of static variables and introducing a special differential mutation pattern for iteration. The highest value of the adaptive differential evolution algorithm piano performance time was 13.5 s, and the highest value of the teaching quality situation was 0.864. With the adaptive differential evolution algorithm, the piano teaching content can be enhanced, students' interest in folk music can be nurtured, and folk music can be inherited and promoted.

“…At a second stage, pair-wise alignment of chroma-based representations of the detected vocal segments is performed and groups of similar phrases were formed using a frame-centric clustering scheme. A more recent work [21], follows the following approach: Automatic transcriptions are segmented into phrases by exploiting certain musical properties typically encountered in folk songs. Then, all pair-wise melodic distances among the detected subsequences are computed, resulting in a distance matrix.…”

Flamenco is a rich performance-oriented art music genre from Southern Spain which attracts a growing community of aficionados around the globe. Due to its improvisational and expressive nature, its unique musical characteristics, and the fact that the genre is largely undocumented, flamenco poses a number of interesting mathematical and computational challenges. Most existing approaches in Musical Information Retrieval (MIR) were developed in the context of popular or classical music and do often not generalize well to non-Western music traditions, in particular when the underlying music theoretical assumptions do not hold for these genres. Over the recent decade, a number of computational problems related to the automatic analysis of flamenco music have been defined and several methods addressing a variety of musical aspects have been proposed. This paper provides an overview of the challenges which arise in the context of computational analysis of flamenco music and outlines an overview of existing approaches.

“…Flamenco is a rich oral music tradition from southern Spain, which attracts a growing community of enthusiasts around the globe. The computational analysis of flamenco melodies, which has mainly been carried out in the MIR community, has revealed algorithmic challenges due to its high degree of ornamentation and improvisation [9,19,14]. We propose a geometric method to approximate the melodic template inherent to a set of flamenco performances.…”

The term melodic template or skeleton refers to a basic melody which is subject to variation during a music performance. In many oral music tradition, these templates are implicitly passed throughout generations without ever being formalized in a score. In this work, we introduce a new geometric optimization problem, the spanning tube problem, to approximate a melodic template for a set of labeled performance transcriptions corresponding to an specific style in oral music traditions. Given a set of n piecewise linear functions, we solve the problem of finding a continuous function, f * , and a minimum value, ε * , such that, the vertical segment of length 2ε * centered at (x, f * (x)) intersects at least p functions (p ≤ n). The method explored here also provide a novel tool for quantitatively assess the amount of melodic variation which occurs across performances.
