"How to Perceive Sound and Enter the Temple of Music" — Let your ears become the gateway to your soul, listen to the shape of sound, and delve into the depths of music.
When you think of Taipei, what's the first thing that comes to mind?
Is it the hustle and bustle of traffic, or the familiar "beep beep" announcement before entering the MRT station?
Sound is not just noise or background music; it leaves a tactile texture on the eardrum, forming an imprint of memory.

Professor Kuo Mei-Nu, a teacher training committee member from National Taitung University who has been deeply involved in the Taitung area for many years, led students in a special lecture on "How to Perceive Sound and Enter the Temple of Music" to re-enable them to listen to and perceive every subtle change in sound and delve into the depths of music.

In his book *The Sound of Discovery* (Il Suono Ritrovato), Italian music educator Ferri Rita points out that "the meaning of listening is that sound is like an 'imprint through the ear,' and the eardrum is like the tactile function of the hand. Because of the eardrum's 'tactile' perception of sound, the sound leaves an imprint in auditory memory, such as a rough or dry sound." When a sound is locked onto by the ear or "seen" by the ear's perception, we begin to want to understand the sound more closely; in words, we use our ears to "contact" the sound.

Professor Kuo Mei-Nu, a teacher training committee member from National Taitung University who has been involved in interdisciplinary aesthetic projects for many years, guided students in a special lecture on "How to Perceive Sound and Enter the Temple of Music" during a teacher training program. She taught students how to listen to sound and perceive music, and discussed the relationship between sound and noise, helping them understand that music is a kind of audible symbol that conveys messages; it can express ideas and has the function of conveying messages.

In our living environment, sound encompasses both "noise" and "musical sound." Advances in electronic technology have significantly transformed and impacted our understanding of music and how we experience sound. Today's noise may even become non-noise, because cultural definitions are not static, and aesthetic standards change over time and space. High technology directly influences people's lives and values, and diverse technological devices offer boundless possibilities for auditory and visual translation.

Music, in every subtle change of sound, produces various forms and colors, whether soft or sharp contrasts, and these are always interconnected. The value of aesthetic education lies not only in the acquisition of knowledge, but also in guiding students to be keenly aware and cultivating sustainable thinking and action. How to cultivate keen hearing and perception is the most urgent and fundamental issue that needs to be addressed in the arts curriculum.
