Like some singing out of tune, unstable rhythm, weak sense of melody, unable to get out of the voice, unable to get up the treble, unable to get down the bass, etc., I can solve a series of common singing problems (such as going to karaoke with friends and colleagues, unable to sing well by myself and embarrassed to sing).

Some friends who love singing but can't find singing skills, or need to learn to sing a few songs or a song to cope with an occasion in a short time, etc., I can guide the professor.
