You may have read somewhere on this site that Indian Natural Scale is identical to Western Natural Scale.

Now, as we discuss the advance theory of music, we have to find the true ‘Natural Scale’. There is no standard Western Natural Scale, so the comparison makes no practical sense. Although, if one does not wish to look into the soul of music, the comparison and the term itself (natural scale) need no further explanation.
Physics of music is a weird phenomenon. For centuries, musician tuned their instruments to each other. What they perceived natural, was natural. Without knowing the frequncies of various notes, everything was naturally in-tune. Now, when we are trying to tie the music to a fixed octave, the natural scale is mere a term. There is nothing natural about any scale played on an electronic keyboard or piano.
Music is an audible art, based on what we hear. To our ears, perfect harmonics sound pleasing. Thus the ancient musical scales were based on perfect harmonics. There are many ways to construct a harmonic scale. Although by doing so, based on the composition, sometimes a few temporary or permanent interval adjustments are required. That is what music is all about. A professional composer or performer knows how to make his composition sound ‘just right’.
Generally speaking, a scale based on ‘just intonation’ is a natural scale. The notes in this scale are established by multiplying the base note’s value with the following harmonic intervals:

Unison= 1 (starting note)
Major 2nd=9/8
Major 3rd=5/4
Perfect 4th=4/3
Perfect 5th=3/2
Major 6th=5/3
Major 7th=15/8
Octave=2
If a piano is tuned according to the above ratios starting from the middle ‘C’, and one wishes to play D major, the intervals will not work. Having said that however, you can change the ‘keynotes’ in C major to get seven different scales, and they all are perfectly natural (more on this later).
We will slowly explore the physics of music. The point is not to remember the frequencies of notes, the point is to understand the natural musical intervals. Indian musicologists explored these phenomenon long before the rest of world. Around 2000BC, The Indian scales based on harmonics had already established and explained in depth.
Nowadays, the natural scale is not derived from harmonics. It is derived from ‘the twelfth root of two’, which has a value of 1.059463 (approx). When this number is multiplied 12 times, the answer is “2”, that is the value of our octave notes (See the list above, the last ratio is 2:1). This system ignores all other harmonics to get a perfect octave. 12 notes of an octave are placed on equal intervals. Although, the values you get through this system are around the desired values, but these are not perfect. This system of dividing a scale into 12 equal intervals is called an “Equal Temperament Scale.”
A violin player cannot play this scale. Only a tuner can achieve these tunings. Humans (trained) naturally play a ‘just intonation’ scale. Yet many musicians think that ‘just intonation’ scales are outdated. Have a look at how one “music wizard” explains the ‘just intonation’ scale in ‘Google Answers’:
“The archaic natural scale uses whole number ratios multiplied by the base note of the octave to achieve the frequency of the other notes. This is an imperfect or dissonant method of composing scales and usually does not sound right.” Perhaps he is a DJ.

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:
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.
