First of all, it depends on how you position yourself. If you want to play and sing, just teach yourself. Let's start with the basic chords. Playing and singing is not difficult. The key is He Xuan. If you are a beginner, you should focus on learning six chords: AM, EM, F, G, C and D at first, because 100% of music is inseparable from these six basic chords, and other chords are also developed on these six chords, such as E7, FM and BM.

If you want to learn fingering further, a musical instrument store is a good choice. You can lay a good foundation and learn some skills. If you are just starting to learn, the price is generally around 60 yuan/hour. For beginners, they should mainly learn to press the strings. Actually, as far as I'm concerned, I haven't been to a musical instrument store, so I just watch online videos and communicate with some guitar friends. Now I mainly practice fingering.

If you want to play the classical guitar, it is necessary to go to a musical instrument store, after all, for beginners. Basic fingering is very important in the performance of classical guitar.

If you decide to study in a musical instrument store, I also suggest that you don't trust the practice steps provided by the musical instrument store, and you'd better contact the practice steps provided by the masters. In this respect, I recommend you to watch the teaching videos of two masters, Lu Jiahong or Liu Tianli (learn more after you form your style). For beginners of guitar, in order to improve their interest, they can try to play and sing by themselves. It is best to choose music from the music score without transverse pressure and gradually improve the training level, because transverse pressure is a difficult point for beginners. If you can't pass, you can't practice guitar well. In order not to die on the horizontal press at first, it is good to use more chords such as AM, EM, G, C and DM to improve the sense of finger force.

Having said that, I hope you can achieve something on the road of guitar (manual typing is tiring, I hope I can add more points after adoption, and the above are all my own summaries of practicing guitar)

Generally speaking, you can know the chords by playing and singing, which takes 3 months.
