Enlightenment of Children”s Songs and Instrumental Music Performance is a simple collection of music for beginners of musical instruments, including Erhu, Guzheng, Pipa, Yangqin, Bamboo Flute, Piano, Bass, Guitar, Ukulele, Saxophone, Drum Set, a total of 11 volumes. The repertoire of each volume is composed of about 60 children”s songs that are familiar to children, and they are sorted by playing skills from simple to difficult. Each sub-volume strives to select the same batch of repertoire, so that each sub-volume is relatively independent and related to each other. The biggest highlight of this set of books is that each track is equipped with two versions of audio: one is a high-definition accompaniment version for performances; the other is a low-voice vocal version for practice. The faint vocals play the role of reminding the melody of the song without interfering with the practice of following the accompaniment.
