Many people often say that music is a bridge for communication between people and people. Even if the language is difficult, you can experience the feelings that the performer wants to express according to the tune of the music. Because of this, there are many changes in the speed of speech, intonation, and voice in music. If it is always the same from the beginning to the end, without any rhythm changes and strong and weak transitions, then this song must sound bland and cannot impress others.

As a time art, what we should think of at any time is contrast and change, so that such sounds can effectively stimulate the auditory organs of the listeners, thereby arousing emotions, and producing joy, anger, sadness, and joy with the changes of music. , worry and other emotional resonance, this should be the soul of music. Therefore, the change of strength is a necessary means of performance. There are several methods in practice: weak and strong, strong and weak, weak and strong and then weak, strong and weak and then strong and so on. In the actual performance of cucurbit flute, the strong tone of cucurbit flute is generally not very strong, usually it can only reach mf (medium strong), and less tones can reach f (strong) treble area usually only has a p (weak), or it can be To mp (medium weak), therefore, when playing, you can try to weaken the sound to form a contrast. Generally, at least three changes of intensity are required, namely: p (weak) - mp (medium weak) - mf (medium strong). Some friends can be weak to pp (very weak) and strong to f (strong), which is equivalent to the comparison of five strengths, namely: pp (very weak) - p (weak) - mp (medium weak) - mf (medium and weak) Strong)—f (strong), the effect of changing the intensity of such music will be very rich.
