There is no fixed time standard.
There is no fixed time standard for music enlightenment. Parents can consciously guide their children to feel the charm of music in their daily lives, so that children can thrive under the influence of music.
The voice of nature
The Sound of Nature is a good beginning of music enlightenment. Let children listen to nature, feel harmony and life, and cultivate their perceptual ability.
Observe the rhythm of music in life
Guide children to observe the rhythm of music in life and exercise their observation ability. Patience and companionship are the key. Don't interrupt the child's interest easily.
