Interaction of motor practice and memory training in expressive piano performance: expanding the possibilities of improvisation.

This paper aimed to investigate the influence of motor practice and music performance experiences on musicians' auditory memory, the effect of auditory distinctiveness on melody recognition, and the differences in the working memory of classical and jazz pianists. The study was conducted among 26 jazz and 24 classical music students at Shenyang Conservatory of Music. To achieve the goal set, a melody recognition ability was analyzed after listening, performing without sound, and simultaneous listening and performing using computer recordings and pianist-taken notes. The study was conducted following repeated measures mixed design. The within-group variable was the learning condition. As the within-participant variable, the number of melody practicing trials was chosen. The type of influence on auditory memory was chosen as a between-group variable. The dependent variables were auditory recognition score, motor imagery ability, and auditory imagery ability. Students' recognition of the heard melodies was assessed by means of a 3-point Likert scale. Pearson's correlation coefficient was calculated to investigate the relationship between working memory and other student characteristics. The study outcomes unveiled that pianists are much better at recognizing tunes they generate themselves in auditory-motor practice than auditory practice alone. It was pointed out that the ability to recognize melody in auditory-motor learning is influenced by its acoustic characteristics. Hence, melodies that are slow in tempo and regular in time and intensity are easier to recognize than more variable pieces.
