1. In fact, you only need to know a little music theory to compose music. Of course, regardless of the level of composition, you can know that three harmonies, one, four and five harmonies can form a complete harmony trend of a song, such as C key, that is, C-F-G-C, which is a simple harmony trend that can pave the way for the song. You can write your own music according to every harmony trend. Of course, the premise is that you should be able to play the basic guitar and have a good sense of rhythm.
2. Music theory is of course important, because a good knowledge of music theory can enrich the harmony trend of your guitar, but there are also wild ways, that is, as 1 said, just make a simple harmony trend and add something by yourself, but without a good music theory, it is difficult to make music move and express it richly.
3. First of all, you will understand why after reading what I said in 1 and 2 questions. I listened to one of her songs, a simple pattern: 1-6-4-5, and then I fixed the music in my heart with this routine. Of course, I have to say that she has her own understanding of music, that is to say, she has music in her heart.
Guitar can express all scales. If you only play melody, you can play whatever you want. The process of composing music is basically divided into two categories: 1 is to make a harmony mat first, make a harmony routine and rhythm by yourself, and then add something to it. I don't agree with this, which limits the space for original music. 2. Hum your own tune, simply write it down according to your own words, then arrange music on it and rotate the accompaniment. This is called arrangement, which is the soul mode of composition, but it needs higher music theory as the foundation.
Seeing this, I realized that the answers to the first three questions are meaningless. In other words, congratulations to the landlord, you are a person with great musical talent. I suggest you stick to it and study hard so that you can make the music you want. This part involves some knowledge of music theory, so it is not convenient to talk for too long. Let me say it briefly. First of all, you need to know what each harmony is commonly used in each mode and what its function is. The first harmony of each mode is the main harmony, which should be used at the beginning and end of the song; Then you need to know what is major harmony and spin, what is minor harmony and spin, and what is the relationship between harmony and spin? There are many contents. I suggest reading a book. There are not thousands of chords, one mode has six commonly used triad spirals, and the other seven chords, increase and decrease and spirals are all changes on this basis. If you want to compose music and rotate notation, I can only give a simple example to illustrate it: for example, if your music is in C key, what are the notes in the first bar? If it is 1, 3, 5, then your music is in C major, your first chord is in C key, and the ending is also in C key. I only say triad. If it's 6,3, it's a minor, so use Am. The mood in major and minor is different. Next, what is the tonic of the next bar? Which chord is more appropriate? Which one to use? Speaking of which, you need to know, know the definition of each chord, and which notes are major or minor. These are just the simplest chord matching methods. I haven't read this kind of book for a long time. Recommend a better book I have read, Guitar Self-study March Pass, which seems to be the name. In fact, beginners' books will all talk about how to score and spin music.
6. I'll drink some water first. . . Well, I think the question I answered above is in vain again. Hehe, you already know how to match and spin! Let me talk about my composing experience: I often have some melodies in my mind, and then I perfect them in my mind. I don't audition because I already know what the scale in my head is, and I don't write it down because I have difficulty remembering music. Hehe, next, I picked up my guitar to arrange music. First, I decided the mode and which key, and then I arranged it with the conventional harmony rotation and the simplest accompaniment. The next step is to improve the arrangement: add some additions and subtractions to transition or replace some harmony, and improvise and add some colors in some places. My classical guitar has passed the 10 level, so I know every note on the guitar fingerboard like the back of my hand, so it's easy. Finally, I added a prelude interlude, on the one hand, to highlight the melody of the prelude, on the other hand, there is a beautiful harmony to follow, which is also an improvisation part. Finally, I improved the rhythm and added some guitar fingering skills, such as playing the board. . .
Having said so much, I wonder if I can help you. Composing this thing, don't have too much purpose, don't compose for the sake of composing, you must have feelings to have satisfactory works. Therefore, composing music has nothing to do with guitar, but a feeling formed in your mind and heart. What the guitar needs to do is to arrange the music, and how to show it more richly. We need a good theoretical foundation here, so let's stop here. Have the opportunity to communicate more. .
