The harp is a long-established European woodwind instrument, used since the Middle Ages. It originated in Italy in the 15th century and flourished in European countries from the 16th to 18th centuries. The harp has a beautiful, mellow sound and is an important wind instrument in Europe, as well as a standard solo instrument in the Baroque era. The harp is playing a great role in the developed countries of the world, both in professional music performance and in general music education. From the Vienna Conservatory of Music and other world-renowned music schools to primary and secondary schools, this elegant and popular instrument can be seen everywhere. Professional harp ensembles and harp research societies also abound. Harp competitions are often held in various countries around the world, and harp music is often broadcast on radio and television stations around the world. The harp has become one of the most popular musical instruments in the world today. The sound of the harp is pure and clear, soft and light, and has been called "the soft flute" and "the flute that sings like a bird". It can be played with the strength of a natural breath, so it is easy for people to obtain a beautiful sound from the very beginning.

The harp is usually an eight-hole instrument in a series, and there are five types of harps commonly used for playing: the soprano (Sopranino), the soprano (Soprano or Descant), the alto (Alto or Treble), the tenor (Tenor), and the bass (Bass). These recorders can be used in an orchestra to play a wide variety of music.

The "six-hole harp" is a combination of the harp and the traditional Chinese bamboo flute, and the fingering is quite different from that of the "eight-hole" harp.

The harp is also a twelve equal-tempered instrument, which can be transposed at will and has a range of more than two octaves, making it extremely expressive. Therefore, learning the harp, like learning any other Western musical instrument, can effectively cultivate the concept of fixed pitch and effectively improve one's professionalism in music. In many countries, the harp has become a popular instrument with the largest number of learners, and this is also true in China.
