1. Thaats in Hindustani Classical Music

The thaat system in Hindustani Classical music is a classification scheme which organizes the various raags based on certain rules (which we will describe in detail). This can be said to be a framework through which the raags can be grouped together under an umbrella definition. It is well understood that raags existed before the system of thaats was developed. thaats were developed and created by Pt. Vishnu Narayan Bhatkhande, who was inspired from the Mela System of Carnatic Music from South India [1,2]. To understand a detailed description of Hindustani Classical Music and the meaning of terms used in Hindustani Classical Music, please refer to [3,4]. Figure 1 shows the various thaats in Hindustani classical music.
The table below shows the various thaats and the notes which are used in them.
Preprints 187704 i001
There are some rules a thaat must follow [1,2,5,6,7].
  • should include a minimum of 7 out of the 12 notes (including komal and teevra)
  • can only have a single aaroh
  • thaats are not raags, but raags are derivatives of thaats.
  • thaats cannot have both pure notes and the komal or teevra of that particular note
We will keep our description of the thaats to the fundamental level and not being extremely detailed. The aim this article is to give an exposure to the fundamentals of thaats and the various raags belonging to the thaats. In our future research, we would definitely like to study each thaat in a more detailed and exhaustive way.

2. Prahar System of Hindustani Classical Music

The prahar system of Hindustani Classical Music is based of the time period of a day. A day is divided into 8 prahars with each prahar being a 3 hour period. Each prahar is based on the mood, energy, feeling and other emotions which someone goes through depending on the time of the day [1,2,5,8,9,10]. The reasoning behind the raags associated with timings is because raags are not just scales or a collection of notes. Every part of the day is associated with a certain emotion due to the sunrise, or start of the day, going towards mid-day, then afternoon and then sunset. The dynamics and nature of each part of the day has a variety depending on the mood of the day, so the raags are allocated timings which bring out those particular emotions. Some raags may be common in multiple prahars because of the various sources we have used. The prahars and their timings are shown in the table below:

3. Conclusion and Future Work

This study is a detailed study of the various thaats and the classification and grouping of raags based on thaats, the timing and the moods of the various time period of a day. The readers of Hindustani Classical Music or even light music should be able to connect with the different aspects of raags through this study. The diagramatic approach makes the information easily accessible to readers because they don’t have to go through multiple resources, including books and the internet.
Our future work is to understand each thaat in more depth and detail along with the respective raags in those thaats. Currently, we are also working towards a deeper and a more fundamental understanding of the thaats and their respective raags.
