1. Introduction Many of us have seen this almost reflexive scene in movies and TV shows: the electrocardiogram (ECG) on the monitor suddenly becomes a straight line; the atmosphere freezes, the doctor shouts, and the defibrillator is brought in; "Clear!"—after the shock, the ECG waveform miraculously returns to normal…
1. Starting with the Black and White Keys: The Smallest Structural Unit of the Musical System. In a previous article (see: The Awakening of Sound - Basics (Part 1): Pitch Structure and Auditory Stability), I mentioned an important fact: the fifth interval describes the auditory proximity or distance between pitches. For example, C and…
1. The immediate reason for writing this article, when stability begins to require maintenance, is that a cross-border transit service provider I've relied on for a long time (which I've always considered the most technically professional) recently went bankrupt, causing my access architecture, which had been running stably for years, to suddenly fail. This change forced me to…
1. A Huge Pitfall Encountered When Logging into Telegram on a New iPad Recently, considering I no longer needed mobile work, I sold my unused M1 MacBook Pro and iPad mini 6 on Zhuanzhuan (a second-hand marketplace app): Then, I added some money and exchanged them for cellular versions with national subsidies…

Although I don't use it regularly, every time I do need to use it, I find that I've completely forgotten the relevant knowledge and have to go through it all again. This is because I've learned a certain knowledge point without reinforcing it through writing…
1. From Pitch Names to Solfège: Why Singing Requires a Different Perspective In a previous article (see: The Awakening of the Voice - Basics (Part 1): Pitch Structure and Auditory Stability), I introduced a fundamental fact of the modern vocal system: sound does not exist randomly. Starting with overtone structure, a certain…
1. Why did I write this article? The purpose of this article is not to create a vocal tutorial, nor is it a complete overview of music theory. It's more like a record of my own reflections—an attempt to answer a simple yet complex question: What am I actually listening to? And why are these sounds perceived by me in this way…
1. Why do we find a song pleasant to listen to? Sometimes I ponder a very simple question: why does a song sound "pleasant"?
