If it is for children to listen to, it must be Chinese classical music. Because classical music can indeed promote the development of IQ and EQ. This effect does not mean that children must understand the music or even understand the connotation of the work, but it is formed subconsciously. Also, the classical music has passed the test of hundreds of years, and the reason why it is still widely circulated is the performance of the classics. Music expresses beautiful things. Long-term listening is actually a subtle aesthetic education for children, and their aesthetic standards will be improved accordingly, which is more effective than blind preaching. Of course, all of these are equally suitable for adults. Specifically, you can listen to piano music by Mozart, Chopin, Schumann, etc.
