Hire a voice coach that has extensive history in Indian music. A voice coach is an important tool for any singer to have. When learning a language other than the native language of a singer, it's particularly vital to learn the language correctly. You don't want to insult someone's heritage by mispronouncing their message throughout the song.
Select a specific classical Indian song that suits your particular singing voice. A voice coach also helps in selecting a song that is suitable for you because they have extensive training in the voices of people and helping them to discover what ranges and styles they sing best. Listening to classical Indian music can help you to get ideas of the songs you might like to recreate.
Study the history of classical Indian music. Classical Indian music has a very extensive history and is one of the most complex musical systems in music. Having a sound understanding of the notation that classical Indian music uses will really help your ability to sing songs of the genre.
Apply the skills of proper breathing to your singing. The way you breathe is extremely important in singing. Breath control is the practice of singing a constant note and holding the note for the longest possible amount of time without discomfort. In time and through practice, you can build up a higher support system for your breathing.
Practice your song and techniques. Practice is the key to success in any endeavor. The more ready you are for a performance, the better your performance will be. It's important to never over do it; you don't want to ruin your voice by abusing your vocal cords. Proper intake of water and using the proper stomach muscles to amplify your voice will ensure a better result.
