Ibn Sina and Farhat

Danny,

For your enjoyment and edification, I just posted p. 1047 from my
book _Musical Mathematics: A Practice in the Mathematics of Tuning
Instruments and Analyzing Scales_. This pages shows a comparison of
interval ratios as found on Ibn Sina's ud and in Hormoz Farhat's
book: _The Dastgah Concept in Persian Music_, 1990. Cambridge
University Press, Cambridge, England.

Cris,

Thanks for the link, and also for showing how ibn Sina
derived some of the interval ratios as intervals above
or below others (as implied by the multiplications and
divisions).

Did ibn Sina describe his actual tuning procedure in
full?

Regards,
Yahya

For Michael Zapf -- Re: [tuning] Ibn Sina's mujannab

Dear Michael,

Here are the eight ratios on the Bamm (the lowest string) of Ibn
Sina's `ud:

Open: 1/1

Fret 1: 273/256

Fret 2: 13/12

Fret 3: 9/8

Fret 4: 32/27

Fret 5: 39/32

Fret 6: 81/64

Fret 7: 4/3

Farmer's English translation of Ibn Sina's `ud tuning description
appears in:

First and Second Series_. Longwood Press Ltd., Tortola, British
