I can't understand the second chapter of the basic music theory course. Just notes and rests. You can write notes, but you don't know how to use rests.

First of all, you should remember the duration from full stop to 64-minute stop. Its duration relationship is 2: 1, that is, a full stop equals two binary stops, a binary stop equals four-minute stops, and so on. A rest or note with dots will increase the duration of the rest or note itself by half or half. For example, an additional four-point pause equals four-point pause plus eight-point pause, and if an additional four-point pause is added, a sixteen-point pause is added after the result of the additional four-point pause. The conclusion is that attaching a quarter note equals to a quarter pause plus half of it (quarter pause), and attaching a quarter pause equals to a quarter pause plus half of it (quarter pause). When you say half, you should subtract one-half (half) of the duration of the pause or note, and double is to increase one-half (half) of the duration of the pause or note. The same is true for other questions, but only if you remember the above. First of all, we must do more in the future until we see how many are equal. It's detailed enough anyway. If you can't say that, it's no use for Yin Zhong's theory professor to sit in your stomach. Just kidding, classmate, did you give me too little reward? Hey! I can't add it if the level is not enough. If you trust me, please tell me your email address. I will send it to you in word, and I will help you for the sake of being a good scholar. But to be honest, such a simple thing is very difficult to learn, and the modal analysis behind it is enough for you. I didn't mean to hurt you.
