Which pair of Tal has open 'Bols'?

Question

Accepted Answer

The correct option is 3:
Students, this question tests your foundational knowledge of *Tal* and the distinct sounds (*Bols*) used for different drums. The phrase "Open Bols" (*Khula Bols*) specifically refers to the resonant, booming, and non-muted strokes played on the *Pakhawaj* or *Mridangam*. The Taals traditionally associated with the *Pakhawaj*, which were used to accompany instruments like the *Rudra Veena* and the *Dhrupad* style of singing, are known for having exclusively open *Bols*. Both **Teevra Taal** (7 beats) and **Sooltal** (10 beats, or *Soolfak*) fall into this historical category of *Pakhawaj*-based Taals. Their constituent *Bols* like 'Dha', 'Din', and 'Kita' are struck with full, open hand contact, creating a powerful, open-air resonance, which is the defining characteristic of this group. This makes the pair the correct representation of open *Bols*.

The incorrect option is 1:
The pair Iktal and Keharwa is incorrect because they are quintessential *Tabla* Taals, and while they do contain some open *Bols* like 'Dha', they also prominently feature "Closed Bols" (*Bandh Bols*) that are muted or soft, such as 'Tin' and 'Kat' in Iktal. Iktal, with its 12 beats, is a major *Tabla* Taal used for classical compositions. Keharwa is a simple 8-beat *Tal* used widely in light music; although its *Bols* are mostly open, it is not paired with a Pakhawaj *Tal* and does not form a pair of purely open-bol *Taals* like Teevra and Sooltal. The mixed nature of their *Bols* and their *Tabla* origin invalidates this option.

The incorrect option is 2:
Tilwada and Deepchandi are both strongly associated with the *Tabla* and the accompanying styles of music, such as *Khayal* and *Thumri*. Tilwada is a 16-beat *Tal* used for slower *Khayal* compositions and is structured almost identically to the standard *Tintal*, heavily relying on closed *Bols* like 'Tin' and 'Kat'. Deepchandi is a 14-beat *Tal* that uses soft, lyrical *Bols* which are mostly closed, fitting the emotional context of *Thumri*. Therefore, neither of these is a true open-bol or *Pakhawaj*-based *Tal*, making them an incorrect selection.

The incorrect option is 4:
The pair Khemta and Rupak are incorrect because they are fundamentally *Tabla* Taals that primarily use closed *Bols*. Rupak *Tal*, a 7-beat cycle, is particularly famous for beginning with *Bandh Bols* ('Tin Tin Na'), which means its structure explicitly relies on soft, muted drumming strokes. Khemta is a 6-beat *Tal* which is often used interchangeably with *Dadra* and is also a *Tabla* *Tal*. Since both of these *Taals* are defined by the prevalence of closed or muted *Bols* and are played on the *Tabla*, they fail to meet the "open Bols" criterion.
