1. First of all, most songs are written after getting the lyrics. Therefore, it is crucial to study the artistic conception of the lyrics first. Some people often fail, such as "June Rain". The melody and lyrics are extremely inconsistent. 2. After studying the lyrics, don’t be too busy trying to spell out the chords. Memorize the words, and when you are inspired, you can even write several versions of music with one word. 3. When you feel inspired, hum a whole paragraph based on a melody. Because if it is always intermittent, it will make a song feel incoherent. And be sure to memorize it, as you may only think of a certain melody once in your life. When memorizing the melody, never follow the pitch relationship of the notes. If so, when you think of it next time, you will remember the pitch relationship but will definitely forget the interval relationship. Memorizing the melody only requires repeating it in your head for a long time. Just like me, I was often scolded by the teacher just for one or two lines of music in class, or I didn't listen to the class and couldn't do my homework, so I had to redo it! But it's still worth it. 4. When the melody is all composed, plan the structure of the entire song. Or interspersed with some RAP, such as those in the middle of "Hair Like Snow". Structure sometimes plays a big role too. 5. Arrangement (accompaniment), which requires some knowledge of chords. This is the only step in the production of a song that requires the use of chords. If it is a piano accompaniment, usually the right hand is played first, and then the left hand is arranged based on the right hand. Don't stupidly make up some four-part combination. If it's a guitar or the like, it's relatively simple. Just figure out the progression of the chords and it's basically OK. The chords should be in harmony with the main melody and the pitch of your own voice. If there are multiple instruments, chords are used more. If you want to find a special and outstanding feeling in the ordinary, it depends on your personal skills and musical accomplishment. As for the detailed issue of chords, it is difficult to explain in one sentence, and I will talk about it later. 6. Harmony, harmony actually plays a role in setting off the main melody. It should be noted that the general harmonies sound very ethereal to me. No, no, there are many harmony parts at the end where two voices are obviously singing, such as "In the Name of the Father", "The Little Blacksmith of Milan" and so on. 7. When you are almost ready, it is time to record. An ordinary recorder will definitely not work. There are many recording software on the Internet that are pretty good. Recommended one: Cool Edit Pro. It is relatively practical and not difficult to operate. I wish you success.
