It's too general to take music hobbies to a higher level. I'll take "improving the ability of piano improvisation" in your supplementary explanation as your goal. More specifically, she has the ability to "tell you her favorite singer in a bar, so she goes on stage to play a song." So, what you need to practice is: singing. Find a song, listen to the melody, and then listen to the harmony. If it is a song with pure piano accompaniment, just listen to the accompaniment directly. Of course, most songs are complicated, so it is necessary to rearrange the accompaniment into a piano solo, which will be discussed later. Singing requires a lot of practice to improve yourself in two ways. One is difficulty, the other is speed: from two tigers, to kissing goodbye, to chrysanthemum terrace; From one song a day, one song an hour, to one song every 1 minutes. After stripping a certain amount, with the improvement of these two abilities, you will find that the harmony routine of Chinese pop songs is really not too complicated. While listening to a song and remembering the melody lyrics, you will basically hear the harmony and remember it. Even you will find common Chinese pop music harmony/bass routines, such as 17654325 and 25147366, which is beside the point. At this level, basically according to the speed, rhythm and rhythm of the song, choose the corresponding accompaniment texture and chord transposition, with the melody/sub-melody of the right hand, and you can cover the general song. The first time the main song uses column chords, the chorus uses arpeggios, the second time the main song uses incomplete arpeggios, and the second time the chorus uses complete arpeggios. At the same time, pay attention to adding reinforced chords when the climax is repeated, and so on, which are all commonly used techniques. Note that at this stage, you can pick up some pop songs accompanied by pure piano to experience how to use the texture change of piano to reflect paragraph contrast. The same harmonic progression, how to express the first paragraph, how to express the second paragraph, and what to change the texture and AB paragraph have both differences and exercises, and at the same time reflect the sense of hierarchy. For example, it's dark and dark, such as Someone like you, and don't rip off Teacher Lin Hai's Empty City, which is abusive to hands and hearts. As for impromptu adaptation, impromptu solo and the like, they all belong to professional player projects. You're a joke if you don't lay a good foundation and force yourself on the horse. Beginners should first practice the above well, so that they can remember the harmony, melody, rhythm and texture after listening to the general pop songs twice and three times. They can improvise and sing the lyric songs of Tao Zhe, Jeff Chang Shin-Che, Sandy Lam and Fish Leong without pressure, and even if they have a basic grasp, they can ask a literary girl out.
