Tarana is the most popular and widely performed form of Indian classical music. A special feature of Tarana that sets it apart from other forms is its use of a sing-along-the-slower technique, which in turn, makes for a profoundly expressive medium. The main vocal technique used in Tarana, the Vibrato, is derived from classical music and resembles popular vocal styles in the West. Vibrato is often used to express melodic ideas, while also providing a background note to the rhythm. Vibrato can be heard throughout the piece and appears especially prominently in the introductory choruses.
Though it is possible to play Tarana using only the fingernails, the fingernail versions tend to lack power, tone, and consistency. To achieve a fluid vocal style that expresses the notes as fully as possible, it is best to learn in a group. Many teachers encourage learners to begin in pairs so that one can practice with another and gauge performance after performance. However, even groups will sometimes find that each member performs a different part of the piece using a different vocal style.
Once you have learned the basics, it is important to keep refining your vocal style. The more you perform Tarana, the more your skills will become refined. However, keep in mind that this is also a highly social art form. As with many musical forms, vocalists tend to be judged not only on their ability but on their performance style as well. If you wish to stand out from the crowd, it is important to be comfortable performing the Tarana.
