The Time theory of Raags is an ancient theory. Every Raag has a three-hour time slot in the day. One slot is called a “Pehar”. There are 8 Pehars in a 24 hour day. A Raag performed in its time slot has the most effect on the listener and the performer. Through the ages though, many Raags have been modified, and their allotted time slots do not match with their flow of notes. This incompatibility has created a lot of confusion about this theory. However, if a student knows the basics of the Time Theory, the proper alterations can be made.
At first look, the time theory of Raags alludes many. It seems random, there are formulas however. It is directly connected to the notes used in a Raag. Every Note, when used with certain other notes, has a different effect. That creates certain moods. Based on that, we can divide Raags into three categories:
1. Raags with ‘Komal’ ‘Re’ and ‘Dha’ (second and sixth flat)
2. Raags with ‘Shudh’ ‘Re’ and ‘Dha’ (second and sixth natural)
3. Raags with ‘Komal’ ‘Ga’ and ‘Ni’ (third and seventh flat)
1. Raags with Komal ‘R’ and ‘D’ (second and sixth flat)
These Raags are called ‘Sandhi-prakash’ (dawn/dusk or twilight) Raags. As the name suggests, these Raags are sung in the early morning and early evening. ‘Ma’ (the fourth) note plays a very big role to separate the morning Raags from the evening Raags. In the morning Raags, ‘Ma’ is usually natural and in the evening Raags it is usually sharp. Another thing to remember about these Raags is that the third note (‘Ga’) is always natural. If ‘Ga’ is flat, then the Raags will go in the third category. Importance of Komal ‘Dha’ (sixth) is not as high as Komal ‘Re’. If ‘Re’ is Komal and ‘Dha’ is natural, the Raag will still come under this category. But if it is the other way around, then it will go to the second category.
2. Raags with ‘Shudh’ ‘Re’ and ‘Dha’ (second and sixth natural)
These Raags are sung right after the ‘Sandhi-Prakash (twilight) Raags. So their time slot is around 7-10 a.m. and p.m. Again these Raags must have a Shudh ‘Ga’ (third natural), otherwise they will go under the next category. ‘Ma’ (fourth) plays a big role in these Raags too. The same rule applies here, the ‘a.m.’ Raags have natural ‘Ma’ and the ‘p.m.’ Raags have Tivar ‘Ma’ (fourth sharp).
3. Raags with Komal ‘Ga’ and ‘Ni’ (third and seventh flat)
These Raags have the next time slot in both day and night. In these Raags, the position ‘Re’ or ‘Dha’ does not matter. However, these Raags must have Komal ‘Ga’ (third flat). Importance of komal ‘Ni’ (the seventh) is not as high as the position of the ‘Ga’ (third).
The above categorization is very useful to memorize a Raag’s appropriate time. As I stated earlier, this division is not perfect though. Indian music theory is over 5000 years old. Along the way it has acquired its fair share of exemptions. There are a few other things, which may or may not overrule the above categorization. Raag ‘Yaman’ (name) is an evening Raag. Nevertheless, it is always the first Raag in a performance, regardless of the time of the day. Similarly, no matter it is day or night, Raag ‘Bhairavi’ (name) is the last Raag performed. A few other Raags occupy bigger than a 3-hour time slots and a few are only sung during a special season. Read more about this in the next post.
Murdung is also called Murdungum or Mridungam. It is a very ancient drum and is mentioned in the oldest scripture available (Rigveda 5.33.6.). In ancient times it was called ‘Pushkur’. Pushkur was the favorite drum of Gods. All Godly dances were performed on the rhythms of Pushkur. There are thousands of ancient statues and carvings that give Murdung a very long history.
As shown in the picture, Pakhavaj is made from the one piece of the wood. The bass side is bigger than the treble side. Pakhavaj’s Bayan (left side) is not inked and dough is used to get the bass sound. Higher or lower notes are achieved by putting more or less dough on the head. Because Pakhavaj is one piece, so hitting one side makes both sides ring. That ring distinguishes Pakhavaj’s all over sound from Tabla. The ring is especially obvious when a Thaap (all four fingers flat like ‘Te’ sound in Tabla) is played. A lot of Thaap sounds are used in Pakhavaj, where in Tabla lots of individual fingers are used to get different sounds.
Tabla is tuned with a special hammer. Although any small hammer can be used, but this thing is specially made for this task. It has a blunt head to tune it, a sharp head to fix it and the other side is designed to get the rawhide belt over the wooden blocks. This special hammer is a very cheap tool and it is mostly sold with a new Tabla. A new one can be bought for a buck or two.
Normally a Bayan (the left part) is not tuned to any note. It is just tighten until sounds pleasant by hitting the crown. But some players do tune it to the bass keynote (lower ‘Sa’ or bass fifth (lower ‘Pa’). Some players don’t use an ‘inked’ Bayan. They use wheat dough to get the bass sound. If you have this kind of Bayan, then don’t tighten it before using the dough. It sounds very high without the dough. The other thing to remember about dough Bayans is that the dough should be fully scratch off after every use. Otherwise it is bad for the head. Store your dough Bayan in a mice free zone because if they found it, they will shred it. The dough Bayans are commonly used in the Quwali style playing and are known as ‘Dhamas’.
Some old paintings have been found of a drum which sort of looks like a Baya (left) side of a Tabla, but the modern Tabla is not that old. Most scholars and researchers now agree that a Sufi poet and musician Amir Khusro made Tabla in the time of Emperor Alaudin Khilji (1296 – 1316 AD). He cut the Murdung (or Pukhavaj, an ancient rhythmic instrument, still popular in the southern music) in the middle and put the two pieces side by side. Later developments were made from that design. Some people say that word Tabla, evolved from Middle Eastern word ‘Tubbel’ drum. This much is sure that today Tabla is the most famous Indian drum in and out side of India.
The right side is the sharper side of Tabla. It is made of wood that gives it a distinguished sound. It is available in many sizes, depending on where you want to tune it. The Tabla heads are made from goatskin. A prepared skin is called ‘Pudi’. That is why sometimes ‘Dayan’ is also known as ‘Puda’. A Pudi’s edge has a crown which has 16 holes. A rawhide belt goes through these holes and 8 wooden blocks are inserted under the belt. Dayan is tuned by these wooden pieces.
Please pay attention to the picture and see where these parts are. All the sounds are made by hitting the different parts of Tabla with different kind of strokes. If a Tabla is recklessly hit or tuned, it may take hours to fix it back. It is a very delicate instrument. Although it is moderately loud instrument, but it is the technique not the force, that makes a Tabla sound good.
accordingly. You will see that all the 4/4 patterns you play or hear are not all the same after all. Their accents make them sound different. The sub-sections create a flow and this flow separates a disco beat from a reggae beat. Once you master this concept you will get another creative choice to make to create new patterns.





There are a few notation systems in India but the most famous one in northern music is the one invented by music Pundit Vishnu Narayan Bhatkhande. This is simply called the ‘Bhatkhande notation system’. I will refer to it as the Indian notation system, as this is the only one you will ever have to learn. This is the only system used by Northern Indian classical and pop musician all around India and the world.
