If you listen to the singing produced by someone who is tone deaf for an extended period of time, there is a possibility you too will display some slight qualties of that recently heard tone-deafness and/or miscalculate rhythm. This is commonly referred to as the mirror effect. Which is when an individual unconsciously mimics style or qualities of actions, recently seen or heard. Any type of music or sounds you hear and surround yourself with may have a heavy influence in your own sound production.
(For example, your singing is better if you listen to good singing and your singing is worse if you listen to bad singing)
I researched and conducted an experiment to document how the rhythm and tonal qualities in vocalization change in a person who is not tone deaf, before listening to and after listening to an individual sing who is tone-deaf. I measured the range of scale while speaking naturally and vocalizing through singing of the person who is not tone-deaf. Then had them listen to tone-deaf singing, measured again and compared the statistics. These are the following results and changes I concluded, surrounding the phenomenons in the case of post-listening to the singing of an individual who is tone-deaf.
1:The High-pitch sounds are out of pitch
2:Difficulty and struggling to vocalize in the high register
3:The omohyoid muscle became stiff
4:The thyroid cartilage got into a deep position
5:The voice became slightly hoarse
6:The voice flipped into a falsetto
7:The voice displayed new signs of trembling
8:Breathing techniques drastically changed, and it was more difficult to take and hold a long breath
If you are the type of person who is affected easily by someone else`s singing, please be aware of this problem. My studies show that 50%-65% of all people can be unconsciously affected by the mirror effect. This rate will vary based on these factors, the length of time you are presented with tone-deaf sounds and the degree of intensity of the tone-deaf sounds heard.
Note1:No wonder why listening to good music is good for pregnant women in prenatal training. If the fetus only listens to the singing of bad singers or bad music, they may lose or be slow in the comprehesion of rhythm, have lessened ease in learning and/or less of a chance of displaying future musical talents.
Note2:Individuality and style characteristics are not necessary in the early stages of vocaliztion and are acquired after comprehending and producing accurate rhythm and tone. Tone-deafness can improve with through practice, studying and patience throughout the process.
Please listen to a lot of good music and great singers. This will have a positive influence on your singing voice.
