Today’s expert Brinda Roy Chowdhury has selected Thaat Bilawal for this week. She has this to say about it, “Bilawal is a basic thaat of Hindusthani Classical music. It has come from the word Veraval, Gujarat. All the notes of this Raga are shuddh. However, while we take up the ragas that come under this thaat, it can have some alterations. That is, they can have the komal or what we call the flat notes in them. I will be taking up six ragas that come under Thaat Bilawal. Also, Thaat Bilawal has become the basic scale of North Indian music from early 19th century.”
Bollywood and Thaat Bilawal: Let us discuss a few ragas belonging to Thaat Bilawal and some Bollywood songs based on them.
- Raga Bilawal – Chhookar mere man ko… Yaraana (1981)
- Raga Alaiyah Bilawal – Bhor aayi gaya andhiyara… Bawarchi (1972), Jana Gana Mana (National Anthem) Here the skeleton of Thaat Bilawal is very much there but with a little alteration of Komal Ni in Avroha.
- Raga Bihaag – Tere sur aur mere geet… Goonj Uthi Shehenai (1959) Again, we see the change with the usage of both the Mas in avaroha. Also in aaroha, Re and Dha are not used.
- Raga Durga – Hum intezar karenge… Bahu Begum (1967) All the swaras are shuddh in accordance with Thaat Bilawal. But Ga and Ni are not sung in this raga.
- Raga Deshkar – Jyoti kalash chhalke… Bhabhi Ki Chudiyan (1961) Ma and Ni are the varjit swaras.
- Hansadhwani – Ja tose nahi boloon Kanhaiya… Parivaar (1956) Ma and dha are varjit.
Others like Raga Shankara, Raga Maand, Raga Pahadi and more also come under Thaat Bilawal.
