[seqfan] Re: Arabic Poetry Sequences

[Ali Sada]

Hi All,

 

Dr. Khashanhas published a book about the subject. https://www.goodreads.com/author/show/6949449._
 In thisvideo, there are some basic graphs that show his work.

Dr. Khashan’sideas came from the fact that Al-Farahidi divided the rhythms into five circles, in a fashionclose to mathematical sequencing. I will study these circlesand try to write a paper about them for the Journal of Mathematics and the Arts,as Dr. Allouche suggested. You can see the circles in this video: 
https://m.youtube.com/watch?v=cBYHHNZSewM

The basic ideais that, for example, there are 4 rhythms that come from the “circle” below. Ifwe start with 110, we get a rhythm. If we start with 10, we get another rhythm,and so on.

110 10   110 1010   110 10  110 1010  

 

By the way,Al-Beiruni mentioned, in the 10th century, that Indian scientists had used “numeralprosody.” This was a fascinating discovery for me. It would be great if anIndian scholar on the SeqFan list could provide me with more information orresources on this subject on my personal email (pemd70 at yahoo.com.)

 

On the Matthew Effect, in middle school westudied  “Al-Karaji Triangle” instead of “Pascal Triangle.” Obviously, the triangle is older than both great scientists, but this is how things work. BTW, my middle school was calledAl-Farahidi!

 

Thank you all again and again.

 

Best,

 
Ali

Has Khasan published on this topic in a book or journal article? Have you?
It sounds like if people are likely to look this up in the OEIS (if at
all), they might be more likely to use Khasan's system than yours.

And Khasan's system might have the benefit of standing out better among
fewer sequences of 1s, 2s, 3s and 4s than yours would among sequences of 0s
and 1s.
