Our breath has a tone

Although I cannot say for sure that it is a completely easily distinguishable tone, but yes – our breath has ‘a tone!’
I tested this theory, using a recorder.
The findings are as follows:
I selected a testing group and asked each person to play the same melody using a recorder. When comparing the playback recorded sounds, I found that even though each test subject used the same instrument and played the same melody, every tone varied with each individual.
As a result, it can be determined that the breath has a tone.
Breath comes out from the body passing through the lungs, the bronchi, the glottis, the laryngeal ventricle, the piriform recess, the pharynx and the oral cavity.
Exhaled air is different with each person, depending on the body’s varied qualities of the above tissues such as shape, size, length, weight, hardness or angle.
These differences affect the tone of our breath when blowing into the recorder.
The main factors that influence voice tone production are not only the five resonance chambers, but also exhaled air.
It’s true – in all over the world, no one has the same voice.
