1 C(Sa), F(Ma), G(Pa), were called “Chatushshrutik” meaning have 4 shruti distance before them.
2 D(Re), A(Dha), were called “Trishrutik” meaning they have 3 shruti distance before them.
3 E(Ga) & B(Ni) were called “Dwishrutik” meaning they have 2 shruti distance before them.
4 It appears Dweepta type of shruti have position at centre of dividing chord into two parts like Sa (C tone ) , Ma (F tone ) , Ga 1st shruti (D# tone) , & Ni 1st shruti ( A# tone)
5 One shruti distance was understood as one shruti up called Mrudu or soft by 80/81 ratio One shruto down or ayata shruti or extended by (81/80) as seen in difference in positions of “Fifth tone of SaMa singing system which is A tone” on Mrudu being on 5/3 & Sharp being on 27/16 so 81/80 or 80/81 being one shruti called “Pramana shruti” or “ratio distance taken as unit for measurement”.
6 there were three scale described within an octave called three gram system
षड्जपंचमभावेन षड्जे ज्ञेयाः स्वराः बुधैः । ( C – G ratio was taken for knowing of tones in Shadja gram by knwoledgable people )
गनिभावेन गांधारे मसभावेन मध्यमे ।। ( E – B ratio was for understanding Gandhara gram meaning E# & B# in Gandhar gram & “F – C ratio” with corresponding “G – Octave C” ratio for knowing tones of Madhayam Gram )
यात रिषभ धैवत यांचा उल्लेख नाही कारण “षड्जे, गांधारे, मध्यमे ’’ यांचा रोख ग्रामांकडे आहे. Meaning there is no mention about tone D & A as these mentions C , E , F tones as here this is description of gram system of Indian Music.
मध्यम ग्रामे तु श्रुति अपकृष्टः पंचम कार्यः पंचम श्रुति उत्कर्षात अपकर्षात वा यद अंतरं मार्दवात आयतत्वात वा तत् प्रमाण श्रुति ( भरत ना.शा. अ.२८ पृ. ३१८ ) ( हिं.सं.प. अ.२ पृ. २२ ) This is usually mistaken as mention of pancham as fifth tone but here one has to understand that these descriptions are as par Sama gayan system where it is mentioned that “fifth tone is Dhaivat or A tone” and not fifth tone or G tone as interpreted by people !
So as par C-G ratio system we get C on 1/1 then G tone comes on 3/2 from G on 3/2 we get on 3/2 ratio (on 9/4 tone octave D#) so on 9/8 D# from D# on 9/8 so we get on 3/2 from there on 27/16 A# tone this is the fifth tone mentioned in Sama Gayan Here we note that position of A is on 5/3 ratio as per shloka सपयोः मध्यदेशे तु धैवतस्य श्रुतिः भवेत Meaning in the centre of C-G ratio which would be on 5/3 as F – Octave C so F on 4/3 F & 6/3 octave C so 4/3 – 5/3 – 6/3 is the position of A tone & Ratio between A# on 27/16 and A tone on 5/3 is the “Pramana Shruti” ratio of 81/80 so when you move Fifth tone A from its position 27/16 by one shruti distance 80/81 one gets Madhyam gram A on 5/3 by making it softer which is meaning of word मार्दवात आयतत्वात वा Mardavat is softer & Ayatatvat meaning extended by 81/80 on 27/16 Here we also understand meaning of terms described as types of shruti !
षड्जः चतुःश्रुतिः ज्ञेय ऋषभः त्रिश्रुतिः स्मृतः । व्दिश्रुतिः च अपि गांधारो मध्यमः च चतुःश्रुतिः ।। चतुःश्रुतिः पंचमस्यात त्रिश्रुतिः धैवतः तथा । व्दिश्रुतिः तु निषादः स्यात षड्जग्रामे स्वरांतरे ।।
व सामगानात पाच सूरांचा वापर होत असे व रेध हे षड्ज–पंचम भावात ठेवले की परिणाम तसा होतो
य सामगायनाः प्रथम स वेण्णो मध्यम स्वर । ( In SaMa singing First was F tone (called Ma)
यो द्वितीय स गांधार तृतीय ऋषभ स्मृत ।। ( The second one was E tone & third was D tone )
चतुर्थः षड्ज इति आहुः पंचमो धैवतो भवेत् । ( fourth tone was called C with fifth being A tone)
षड्जे निषाद विज्ञेय सफ्तम पंचम स्मृत ।। ( Sixed was known to be B tone and seventh was G tone)
म्हणजे म – ग – रे – सा – ध – नि – प या क्रमाने सात सूर लावले जात हे स्पष्ट आहे. ( This means tones were expressed in order F – E – D – C – A – B – G )
साम गायनात स्वर अवरोही क्रमात होते हे स्पष्ट वर्णन केले होते अवरोहणात प्रतिषड्ज म्हटलेला पंचम सां-नि-ध-प चतुर्थ येतोच
दीफ्तायता तु करुणानाम् मृदुमध्यमयोस्तथा ।
श्रुतीनाम् यो अविशेषज्ञो न स आचार्य उच्यते ।।
दीफ्ता मंद्रे द्वितीये च प्रचतुर्थे तथैव तु ।
अतिस्वारे तृतीयेच कृष्टे तु करुणाश्रुति ।। ( ना.शि.कं. 7, 9-10 पृ.40-41)
“Dweepta” obtained by “dividing into two” Also Karuna (situated on 16/15 resembling smallest moon after No moons day ! after full moon day of dweepta the brightest tone !) In between being Madhyama or centre position ratio 15/16 from 9/8 which is 135/128 the position & before it mrudu position 80/81 of 135/128 being 24/25 or 25/24 ratio which is ration distance between two shruti positions of E tone or Gandhar of the two E being situated on 15/16 from 4/3 F tone which is dweepta so E is Madhyma shruti where as D# tone which is 1st shruti of Gandhar is Dweepta as it is centre of C & G so on 5/6 ratio !
तर करुणा ही अतिस्वारे वा ध व तृतिय म्हणजे रे आणि पंचमात (कृष्टे) यातच असतात This means Karuna type is seen in Atisware rone which is fifth tone comming after Shadja or C tone in SaMa singing , also in third tone which is C# tone or 1st shruti of Re or D tone called as C# & also in G tone called Krushte meaning one which is in attraction or consonant with C tone with though 1st shruti of this G tone. Its Karuna as it is on 16/15 ratio from Dweepta shruti of tone F !
This indicates that This Jaati or type lable of shruti positions is linked with positions of tones as well as planets & Pythagorus had knowledge of this as this knowledge was universal !
यातूनच वादी संवादी साकारतात असे जाणवते रे–ध , प–रे , म–सा , ग–नि इत्यादि.
हे श्रुति जातीचे ज्ञान असले तरच तो आचार्य संबोधला जातो. If Teacher has knowledge of these positions of shruti system then only he was called Acharya meaning worth following him !
याप्रकारे हे श्रुतिंचे ज्ञान असले की मगच त्यास आचार्य संबोधता येते.
याप्रमाणे ग्रामांप्रमाणे श्रुति स्थानांचा तक्ता सध्याच्या 1/1 सा 1 श्रुति करून असा होतो
षड्ज ग्राम ( सारेगम – पधनिसां ) षड्ज –पंचम भाव

Here C or Sa Tone starts
One can see after every third tone calculation calculation a correction of 81/80 becomes applicable to correct the tone to positions comming as per sanskrit shlokas giving ratio proportions these are C – G – D – A – E – B – F# – C# – G# – D# – A# – D# – B – F – C
Why C was kept on 240 in Indian music ? Answer is Circle is 360 degree & from 360 on 2/3 ratio is the frequency of 240 & 360 degree if divided 1/3 then it is 120…. So 120 degree three parts form three parts of day from morning 8 to 12 am then afternoon being from 12 to 4 pm & then from 4 to 8 pm being evening This was concept of trikal or threee parts of day & further 3 parts of night from 8 to 12 mid-night then 12 mid night to to 4 am midnight time & from 4 am to 8 am early morning like wise musical Classical Raag system was divided to suit the times & was played all over world on the gates of villages & Temples This classical music was called “Marg Sangit” or Music indicating the direction in which you are travelling ! Apart from this their was “Desi Sangit” or locally popular music ! Over a period of time people forgot rules of Classical music & local music became popular dividing world by music in addition to local languages ! As people stopped understanding sanskrit nobody could answer questions about shruti -swara- Raga system ! This is attempt to demystify the same ! C – G – D – A – E – B – F# – C# – G# – D# – A# – D# – B – F – C when we start 1 st tone on C on 1/1 then G tone comes on 3/2 on 17th shruti ! Then rom G tone on 3/2 from this G on 3/4 is 9/8 which is ratio of D tone on 7th shruti ! from this D tone on 9/8 , on ratio distance of 3/2 is 27/16 which is A tone on 20th shruti ! After this rom A tone on 27/16 if you see on ratio 3/4 we get 81/64 which is E tone 303.75 but 4 th A tone or Shuddha Dhaivat which comes on 405 is correctd by 80/81 so on 400 then this A on 400 is the 19th shruti of A tone ! This A tone or Dhaivat is 19th shruti of A tone or Dhaivat ! After this 5 th E tone or Teevra Gandhar gets automatically correctd by 80/81 so from 303.75 to 300 then then from this E tone on 300 we get on 3/2 ratio B tone on frequecy 450 which is 22nd shruti ! we start from reverse end 23 rd shruti Octave C on 480 so on 2/3 is F tone or Shuddha Madhyam on 320 is 10th shruti ! then from this F tone on 320 on ratio of 4/3 is 10 th
