Many people ask questions like "If we want to sing Film songs, why should we learn Classical Music"?
Classical Music is a well stuctured music, which ranges over lots of other subcategories, giving an exposure to students to newer and advanced dimensions of music. With regular Riyaaz, one can shine outstanding. Vocal Classical Music is like Vocal gymming. Like by regular gymming one develops very good muscles, similarly with regular riyaaz, characteristics of voice improve, like depth, tone and texture of voice, ability to reach higher and lower notes easily and sustain there for long, also jumping across notes with ease. etc.
Since learning classical music gives your voice overall improvement and also knowledge about swaras which is very essential when it comes to rendering film songs, once should learn Classical Music even if their calling is for Playback.
