Pure music (idiom in the field of music): Pure music is music without lyrics in the original intention of composition. As pure music, this music mode completely expresses the author's feelings with pure and beautiful music, so it is generally referred to as pure music. Although it has no lyrics, it is perfect with its own beautiful tune. Because of this, the composition requirements of pure music are very high. To make an excellent pure music, in addition to a lot of inspiration to support composition, the author also needs to have deep attainments not only in music theory, but also in life experience, personality and spirit.

Light music: also known as "emotional music", refers to instrumental works in popular music (the accurate concept should be commercial music, that is, music created for profit), excluding music with strong rhythm such as rock music and disco.

Light music interprets music in a popular way, and its source can be original or adapted from classical music, pop music or folk music. Light music is usually played by a small band, with simple structure, lively rhythm and beautiful melody. Light music can create a warm and romantic mood with casual nature. Light music originated in Britain after World War I, reached its peak in the middle and late 20th century, and was gradually replaced by new era music at the end of 20th century, but it still has some influence today.
