As a unique national wind instrument, double tone fenugreek is a product of innovative design based on the traditional single tone fenugreek. Its biggest feature is that it is equipped with one or more artificial blow holes and resonance cavity connected with the tube, so that the performer can issue two different sounds at the same time on the same instrument, which greatly enriches the expressive force and musical level of the gourd.
First of all, the double-tone fenugreek tube design expands the vocal range, which can play the main melody and the harmony part at the same time in a piece of music, enhancing the three-dimensional sense and fullness of the music. For the performer, it can not only experience the fun of more complex music arrangement, but also enhance the appreciation and artistry of music performance.
Secondly, the playing technique of double tone fenugreek is improved compared with that of single tone fenugreek, which requires players to have a higher degree of mastery of breath control, finger-coordination and double tone coordination. However, it also provides learners with new challenges and opportunities to break through themselves, which helps to improve their performance level and music literacy.
In addition, double tone hulusi has more space in the adaptation and creation of songs. It can more closely represent some music works that originally require multi-instrument ensemble, so that a single person can complete a colorful musical interpretation.
In general, the design of double tone fenugreek tube is an innovative move, which not only retains the traditional charm of fenugreek, but also gives it a new musical expression, which is a successful attempt of the modernization of national Musical Instruments. For fenugreek lovers and professional players, learning and using double tone fenugreek is undoubtedly a good way to deepen the understanding of traditional music and broaden the horizon of music.
