A review of the differences between musical genres and performing skills in different periods

Playing skill is the basic condition of musical instrument performance, and its level directly influences the timbre and musical expression of the work. In order to make music more appealing, it is essential to improve performance skills. Only by mastering the flute playing skills skillfully, can the work be more vocal, the timbre is soft, and the timbre is more unified, so that the thoughts, feelings and profound connotations of the musical works are more deeply rooted. The generality of music genre, that is to say, can fully show the common principles of music creation in a period of music and the criterion of musical aesthetics. The individuality of the music genre fully demonstrates the individual characteristics of the composer. In the music works in different periods of the musicians, the specific performance we can see the typical character of a music period, different features also can feel different with the composer.

Perceived Competence and Skill Development in Physical Education： The Effect of Teacher Feedback

This study examined the effects of feedback on perceived competence and student performance in physical education. The sample （N = 113） consisted of fifth-grade physical education students, recruited from two elementary schools and randomly assigned into small groups. Participants within each group were randomly assigned to receive positive general, corrective informational, or no feedback and completed pre- and post-task questionnaires. Groups were given a lacrosse shot task presentation and then completed a lacrosse shot pre-test, practice session, and post-test, including a pre- and post-test. During the lacrosse task, teachers administered feedback treatments to participants at the rate of every other attempt for a total of six feedback statements, excluding the control group. Lacrosse experience was found to be 2.45 on a 9-point Likert-type scale, demonstrating that the sample was unfamiliar with the lacrosse skill. Three separate split plot 2× 3 analysis of variance （ANOVA） tests with repeated measures were conducted to determine whether feedback treatment type influenced participants＇ perceived competence, product performance skill, and process performance skill when considering pre- and post-task measures. The findings demonstrated that feedback appears to have a limited effect on perceived competence and performance during unfamiliar tasks in elementary school physical education.
