Genetics will play a massive role in your singing ability. The shape and power of the vocal folds, nasal cavities, skull, and facial structure will influence your tone and how your voice is sounding. Singing is often thought to be genetic because your gender can affect your voice. The difference in the size of the larynx will mean that men have deeper voices whereas women have higher, breathier tones. The natural timbre of your voice will be determined by genetics, but you can easily learn to train and develop your voice. Pitch, tune, range, and confidence are all different aspects of singing that can be easily learned and developed.
