1 Li Bai: Yan, dream broken

The poem "Ancient Meaning" written by the Tang Dynasty music poet Chang Jian, "Singing and dancing in the blue clouds, the flute boiling beads and foil". The word "boiling" in the poem is wonderful, and the boiling of water is used to describe the flute, which is novel in technique and skillfully transfers and connects the hearing to the vision and touch.

But the breeze stirred by butterfly wings is still rippling in the forest, with a faint fragrance of wood leaves. Suddenly, there is a flute sound-

Suddenly, there was silence in the forest, and even cicadas and birds suddenly disappeared. In the slightly flowing air with the fragrance of leaves, only the intermittent flute is hovering low, and all the sudden passing time seems to fluctuate between the fingers of the piper.

This is beautiful and moving music ... TaBaFeng froze again. ...

The flute again.

Describing the sound of musical instruments is generally called "resonance", and the word resonance is widely used; In order to clarify the difference, I will describe Xiao's difference in sound effects from three aspects.

1 resonance

Refers to the simultaneous occurrence of multiple overtones (frequency doubling overtones) of Xiao sound, which controls the depth (strength) change of overtones.

Bass is called "fog sound"

The treble is called "underwater sound"

Non-resonance is pure tone

2. Aeroacoustics

Refers to the change of wind resistance caused by wind and blowing angle. Big air sounds can be hoarse, and small air sounds can purify the flute.

Step 3 diffuse

Refers to the effect that the sound of the flute resonates with the flute body (bamboo), which is also called resonance in general musical instruments.

The eagle struck Xiao Yang.

Excuse me, Mr. Wen Song, can you still blow the underwater sound above 1? If so, which sounds should it resonate with?

Wen Song

Every flute is different. Generally, the sound of water is not obvious in the ultra-high range, and its resonance overtone is very small, which is obvious in the gas harmony of the mouthpiece. If you make a flute with high brightness, you can still make the ultra-high pitch have higher harmonics to resonate. The sound of water will appear.

The eagle struck Xiao Yang.

Then only a flute that can play high-pitched overtones can play ultra-high-pitched underwater sounds. Hehe, thank you, Mr. Wen Song!

Bamboo flute is not interested in singing, but human taste is pure joy.
