sitar and tabla and braj and kahriboli and khusrau

BRAJ & KHARIBOLI
In the introductiuon towards understanding Amir Khusrau, Dr. Zoe Ansari says Khusrau spent his early child hood in Patyali, which was the area of Braj speaking populace. After his father's death Khusrau frequently visited Delhi. He writes, "Obviously this lad would always be found roaming about the streets, with servants or others in the neighbourhood. This was an area of refined Khari Boli, which he afterwards called Dehlavi or Hindavi. Having a base of Braj, this inquisitve boy must have enriched himself by the knowledge of Dehlavi."

INVENTION OF SITAR, TABLA & DHOLAK
In Amir Khusrau and Hindustani music Abdul Halim Jafferkhan (b.1927 Jaura, Madhya Pradesh recipient of Padma Shree,1970) writes:

"Hazrat Amir Khusrau has been creditied with a number on inventions and innovatins in the field of music--- vocal as well instrumental........the three most important instruments which are usually attributed to Ameer Khusrau are : Sitar, Tabla and Dholak."

MORE ON SITYAR & TABLA
In Khusrau's Musical Compositons, Jaideva SIngh Thakur (b.1893 Gorakhpur, UP recipient of Padma Bhusan, 1974) writes:

"It is generally believed that Khusrau invented the Sitar. But the sitar is only a development of Tritantri Veena of India. There is no proof anywhere that it was invented by Ameer Khusrau..........nowhere in his writings does he mention that he was the inventor of Tabla."

So here we have two opposite views expressed by two musical scholars. And I am as perplexed as ever.
