Some things manage to remain virtually unchanged. One of these is the concept of time that guides the playing or singing of the ragas of Hindustani music. Over the last two decades, as thematic festivals become a trend, one hears of morning raga festivals, since the raagas are meant to be performed during the early part of the day are rarely otherwise heard. Is it however, necessary to adhere unwaveringly to the time restrictions in a globalised world? In contrast Karnatik musicians perform ragas without reference (baring a few well-known ones) to the actual time of the day or night since very few guru's now-a-days are even aware that such a thing ever existed. For years I have tried asking every teacher/acquaintance/other music students, searched and most importantly other musically-inclined people (who may not be able to create or play classical music but sometimes have more in-depth technical knowledge about each raga and its construction than even students who learn classical music) without much progress.

Mostly live performances for a *single raga* can be an exhausting and exhilarating one and a half hour performance in Hindustani classical, but some Karnatik performers (nowadays) stop short at 20-30 min, which is further reduced by the latest crop of musicians, which again depends on their style and school of music. A few old school stylists, do keep elaborate aalaps and tani avartanams at their live concerts but organisers cite lack of time and may restrict it to a single (maybe two) piece(s) at the most. Elaborate aalaps and tani avartanams (jugalbandi between the instrumentalists and vocalists and/or the former) are done away with, which is highly disappointing.
As far as recorded CD's go, music companies are out to make a fast buck ... Five-ten minutes per raaga is hardly enough for a listener to get into the skin of the raaga. Also the same raaga rendered by another artist can be poles apart in terms of style, artists treatment, and other intricate nuances. So it all depends (to some extent) on a artist to make or break the particular raag.
