Automatic Music Transcription (AMT) is a task that detects and recognizes musical note events from a given audio recording. In this paper, we focus on reducing the latency of real-time AMT systems on piano music. Although neural AMT models have been adapted for real-time piano transcription, they suffer from high latency, which hinders their usefulness in interactive scenarios. To tackle this issue, we explore several techniques for reducing the intrinsic latency of a neural network for piano transcription, including reducing window and hop sizes of Fast Fourier Transformation (FFT), modifying convolutional layer's kernel size, and shifting the label in the time-axis to train the model to predict onset earlier. Our experiments demonstrate that combining these approaches can lower latency while maintaining high transcription accuracy. Specifically, our modified model achieved note F1 scores of 92.67 % and 90.51 % with latencies of 96 ms and 64 ms, respectively, compared to the baseline model's note F1 score of 93.43 % with a latency of 160 ms. This methodology has potential for training AMT models for various interactive scenarios, including providing real-time feedback for piano education.

Until the late 19th century, $\ulcorner$Gagogwonryu(歌曲源流)$\lrcorner$ was a collection of songs which had powerful influence on Gagog tradition. However, its role on Gagog(歌曲) tradition since then is less well known. Generally, it is presumed that Gagog tradition might disappeared by giving way to modern song genre. So this article question that $\ulcorner$Gagogwonryu$\lrcorner$ became extinct rapidly between the late 19th century and early 20th century, and follow $\ulcorner$Gagogwonryu$\lrcorner$ tradition of early 20th century. Gagog instruction for beginner had a clue to answer this question. This instruction was written by Ha Son-il(河順一) who was a teacher and singer in a private music institute. named 'ChoyangGurakbu(調陽俱樂部). Accordingly, this article has processed two phases in order to find out this question. First of all, this article analyzed Gagog instruction that Ha soon-il edited. As a result, it found out that Gagog instruction included the whole $\ulcorner$Gagogwonryu$\lrcorner$'s contents in the 19th century and was transmitted actively until the early 20th century. Second, this article found out $\ulcorner$Gagogwonryu$\lrcorner$ tradition of the early 20th century by analyzing character of ChoyangGurakbu. And also this article discovered ChoyangGurakbu had been managed by an vigorous aid association. Gagog instruction for beginner written by Ha Son-il had spreaded from strength to strength in the early 20th century.

In many respects, the current music education contents are learned, based on results and also, education of rhythm, which is an important component of music, is mostly implemented using scores that are based on existing results. In this study, two rhythm education contents were extracted using the number of cases in mathematics, which is a principle of the process of creating a rhythm. First, 16 rhythm education contents were extracted by calculating the number of cases to include a note and a rest in a beat except triplet Rhythm. Second, two-beat 225 rhythm education contents were extracted by calculating the number of cases to connect this one-beat contents. Rhythm education was applied to music majors in their early twenties using these two rhythm education contents and the effect was proven by the rhythmic ability test. As stated above, this study suggests advanced education contents using existing principles, which appear by going back to the basics of rhythm.
