Learning the piano should follow a certain order. Beginners should first learn basic skills, such as finger posture, strength control, speed control, and practice basic etudes, such as Cherny's piano elementary course. Then learn music theory knowledge, understand notes, rhythms, modes and chords, and deepen the understanding of music works. Then learn playing skills, such as Legato, Jumping, Decorative Tone, etc., to improve the performance level.
