Guitar is the same. You can play a simple guitar song or a song with harmony, or you can call it learning. If that's all, a week or two will be enough.
But I think the real way to learn guitar is:
Classical: In addition to the basic introduction of scales and postures, you should also know the staff and play it by fixed roll call. Primary music can find the pressing place by itself according to the score, and carry out parallel and hook tone processing according to the score. In short, teachers can basically cope with primary music without it.
Playing and singing: In addition to the basic introduction of scales and postures, I also know six-line notation, can press basic common chords, can perform basic primary decomposition and strumming according to the music score, can press chords smoothly without dragging, can flatten without noise, and can compose the smallest chord for my own songs. In short, teachers can use the most basic chords and decomposition to deal with a song.
Finger play: It's similar to classical play, but it can only be composed of staff and notation (I still stubbornly believe that staff must be learned), and I can also handle some basic common effect skills of finger play.
Learn guitar within three months, one lesson a week, more than an hour a day, from the overall statistics, almost. However, the individual is different and the time is different. It does not rule out that individuals can play intermediate music in March, nor does it rule out that individuals have basically not learned it for three months.
There are many factors: 1, the foundation of music theory, the perception and inspiration of music, and the persistence of guitar interest; 2. Physiological conditions, such as finger length and shape; 3. Musical instrument quality and feel; 4. Whether the daily practice time and content meet the advanced requirements. If you want to learn things like "City of the Sky" as soon as you pick up the guitar, you don't want to practice scale fingering, and the prospects are basically not good; 5. Whether there is a tutor, the quality of guitar teaching and whether the teacher's teaching plan is scientific; 6. Personal willpower; 7. Resources, such as materials, the surrounding piano learning atmosphere, opportunities for interactive communication and observation; 8, the regularity of the plan, if you want to review the exam, put this month down and other similar things, it will affect the advanced.
