While some factors are genetic, Rutkowski says that growing up in a musical environment strongly influences whether someone sings well and confidently. The natural timbre of your voice is determined by genetics, but you can learn to train and develop your voice. Tone, range, tuning and confidence are all aspects of singing that can be learned and developed. A genetically good singing voice does not necessarily mean that a person can sing well, he has to learn to sing correctly, which requires musical aptitude.
However, you can also say that a person who has never learned to sing well or who has never given him a fair enough chance does not know how “genetically” good his singing voice is, or may be. Many people will tell you that to become a singer you will have to have natural talent or that you must sing in the blood. The study is quite in-depth, so I'll try to simplify it, its main goal was to eliminate other factors that could come into play and focus only on a small number of families, 73 exactly, that had singing in their genes. What researchers in the field of genetics are doing to determine if singing is in someone's genes is by measuring their absolute pitch, measuring actually I mean that the test subjects are giving a score on their absolute pitch.
This means that everyone can be born with the biological characteristics to sing, but some people struggle to control their vocal cords and produce the tone, resulting in what is considered a “bad voice”. There are a lot of people who have to force themselves to sing higher notes, the problem for them is that they just can't stretch and lengthen their vocal cords, that's just how they were born and they can't alter their vocal cords without surgery. There are gifted and talented singers, who choose not to follow the path of becoming singers for one or more reasons. While the results obtained to date are promising, a more thorough investigation of musical ability is warranted, including a more accurate characterization of musical phenotypes to identify their genetic basis.
I didn't know how to read music, I didn't know anything about harmony, counterpoint, phrasing or interpretation, I had no rhythmic control, I had no idea how to practice or learn music. Watching singing contestants on talent shows, it's hard to believe that everyone has the ability to sing. This is a strictly personal opinion, with no scientific backing or anything, but I think that people who were taught to sing or learn music as children (before puberty) often grow up and have much better voices. Once the genetic basis of a trait has been established using some of the methods mentioned above, the next step is to perform linkage analysis to map the possible genetic loci that predispose to the trait.
We've all heard from some random person that to be a good singer you have to have good genes while having good genes, in fact, will make the journey of becoming a singer much easier, but it's not necessary. Singers who have good singing genes but are not nourished in a way that they love to sing, then their chances of actually becoming singers or even wanting to become singers are quite low. People who tend to have good genetics for singing are often considered to have excellent vocal cords for singing, although this also depends on the type of music they are singing.
