The mirror effect of voice means that your singing is better if you listen to good singing, and your singing is worse if you listen to bad singing. Basically what type of music you hear and surround yourself with can influence your own sounds.
When you listen to a good voice sing, talk or even just music with no vocals … your vocals will be mirroring that good quality. In contrast, when you listen to bad vocals or poor sound quality you will also mirror that poor sound.
In an experiment which analyzed the above circumstances, when comparing people who listened to noisy sounds from a construction site to people who listened to classical music for the same amount of time, people who listened to noisy sounds were observed to have (acquired) more of a rough voice than the classical listeners.
In another experiment, the tester asked some people to listen to ‘only one’ (specific) musical instrument that played classical music for 2 months.
As a result, when listening and reviewing their voice after the experiment, they displayed and produced obvious similar sound qualities of that specific instrument that they heard so often.
I believe this happened, because their voice and mind absorbed the tones of the musical instrument they were constantly hearing. Although, the length of time the sounds were heard and the repetition of those sound qualities also impacted the resulting ability and level of the mirroring.
These supporting facts of positive influence can surely have advantages, if utilized properly and consistently, to target a specific vocal quality and make your voice sound better.
Note: I have been asked, if there is a way to learn the mirror effect of voice which displays a high degree of being exact and precise.
Keep in mind, the mirror effect is not completely exact and precise – I’ll explain as follows:
It is only possible to mirror style, effect and quality. Understand that extreme vocal range changes cannot be mirrored. Be aware and recognize the characteristics of your voice. It is impossible if you have small larynx like a small instrument (for example a flute) and you want to mirror and produce big (like a contrabass) sound.
If your goal is to copy your favorite singer or musical performance in voice, you don’t need a loud voice to mirror those sounds, just use sound repetition by listening as well as singing over and over again.
It’s not easy, but you can duplicate an original/specific sound if you practice enough.
If you can record your voice and check its progress over time, you can expect and hear more observably distinct improvements.
