[Ali Sada]

Hi Everyone,

 

Pleasesee below the "sequences" of classic Arabic poetry. Do you think they should beadded to OEIS?

 

Best,

The "sequences" (called “buhour,” Arabic for “seas.”)were discovered in the 8th century by the great Iraqi scholar Al-Khalil ibn Ahmad Al-Farahidi, who was a linguist, philologist,cryptographer, lexicographer, musician, and grammarian.  



The bahar (sea) has one main sequence. Sometimes these sequences get replaced by "lighter" versions. 

 

Each Arab poem consists of few to hundredsof verses. The verse is called bayt, which is Arabic for house. Each bayt couldbe written as a string of “on” and “off” type of symbols. The “on” sign means “moving,”and the “off” sign means “static.” The original signs used by Arabic scholarsare “/” and “o,” so it is perfectly logical to use 1 and 0 instead.

 

There are 28 Arabic letters, 3 of them arelong vowels (“ɑ” as in bath, “u” as in moon, and “i” as in seen.) There arealso 3 harakat (plural of haraka, which means movement in Arabic.) Theseharakat are actually short vowels (“ɛ” as in pet, “ʊ” as in put, and “ɪ” as inpit.)

 

The structure of the Arabic rhythms is basedon these three rules:

 

i)                   A constant sound that is not associated with any vowel sound is called“saken, which means static.) It is represented by a “0.” For example, the “t”in the word “put” is static, and in poetry it is represented by a “0.”

ii)                  A constant sound that is associated with a short vowel is considered one“moving” part. For example, the sound “p” and the sound “ʊ” in the word “put”are considered one moving part. So, the representation of the single word “put”is 10.

iii)                A constant sound that is associated with a long vowel is considered“moving,” and the long sound is considered static. So, the representation ofthe word “pa” is 10.

 

 

Examples:

Paton= moving “p,” static “y,” moving “t,”and static “n.” 1010

Josephine= moving “j,” static “o,” moving“z,” moving “f,” static “ee,” and static “n.” 101100
