Without a sense of music, you can't make excellent music; Without theoretical knowledge, how can you turn the music chapter presented in your mind into music that others can enjoy?
Everyone should have some musical feelings, because sometimes, due to various moods, they may think of some songs. Perhaps music has produced a * * * sound in their mood, and gradually they can sometimes hum some small tunes that they feel good. This should be the feelings of music. Without this, how can they create?
However, most people may often stop here and cannot move on. I'm afraid it's because they don't study music rationally. He doesn't know whether this little tune is the main theme or the introduction, and what instrument is used? What style? How to add accompaniment and harmony? All these require rigorous music theory study to learn slowly.
Moreover, arrangement is an independent subject, which takes a lot of time to study.
If you have already started to learn, I suggest that when you listen to songs, you should not only listen to what people are singing, but also listen to the rhythm of the drum behind him, what his accompaniment instrument is and what he is doing. Listen to the prelude again. What is the relationship between the episode and the main melody?
On the question of guitar, according to your question, I feel that you have learned electric guitar, and you should know something about the way and method of playing guitar. Compared with folk acoustic guitars, electric guitars should have similar performance, because they all accompany songs, unlike classical guitars, which mainly play music.
But the skills of electric guitar are much richer than folk songs, and it takes time to learn and practice. Usually, you can watch the various performances or how to play the electric guitar in blues music, and maybe you will have a deeper understanding of this instrument.
Although the skills of folk songs are not particularly rich, the stringed sweeping of xylophone is widely used in today's pop music, some of which are xylophone solos and some of which cannot be imitated by electric guitars. For example, many songs of Xu Wei.
Therefore, skills are not overwhelming. If you have time, energy and conditions, you might as well learn and practice.
