One of the most distinctive ideas in Hindustani classical music is that raags belong to times. This is samay — the doctrine that each raag has its proper hour of the day (and sometimes season), and sounds truest then. The day is divided into eight watches, or prahars, and raags are assigned across them.
Morning raags carry a fresh, devotional air; evening raags like Yaman glow at dusk; late-night raags like Darbari are deep and serious. The placement is tied to which notes a raag emphasises — the tradition groups raags partly by their treatment of Re and Dha.
At Saarey the home page even arranges listening by the clock — "Raags For Now" — reflecting this living tradition. Samay is theory honoured in spirit: a guide to mood and authenticity rather than a rigid rule, and you can hear any raag at any time you like.
