The normal, healthy voice of a healthy person is, in principle, suitable for both speech and singing. There are only three differences between a singer and a person who has just started learning to sing: developed ear for music, developed strength, developed skill.
Instructions
Step 1
An ear for music develops in solfeggio lessons. You can hire a private teacher or study on your own, provided that you record yourself on a dictaphone. As an initial exercise, simply sing in a comfortable octave in C major up and down. Then complicate the exercises: do-re-do, re-mi-mi, mi-fa-mi and above until the end of the octave. Then down the same way: do-si-do, si-la-si, la-sol-la. Sing the names of the notes.
Step 2
In continuation of solfeggio lessons, sing one-part numbers from Ladukhin's collection. Later, move on to two- and three-voice (each voice in turn sing, the rest play). And in the performance of the scale, and when singing numbers, record yourself on a dictaphone and listen to understand at what moments you sang out of tune.
Step 3
Vocal strength is developed partly during these exercises, partly during the singing repertoire, partly during breathing exercises. The most popular breathing exercises both among singers and among announcers and actors are the Strelnikov system. Do the exercises every day, first one exercise at a time, adding in a week.
Step 4
Singing skill and selection of repertoire is a question that is resolved exclusively with a teacher. Without his advice, you can fail to guess the technique of performing a complex exercise and plant your voice, take pieces with a repertoire that is unbearable for you or unnatural for your range, make other mistakes that will lead to voice damage.
