=Explanation= 
The tuning tables on this page are specifically designed for the tuning system of the [[qanun]] (see the link for details on the system of tuning and playing a qanun with "mandals/orabs").

The whole table covers roughly the range of a fourth (the range where the ajnas - maqam tetrachords - reside). Each row corresponds to one string of the qanun. In the first column stands the basic (relative) tuning of a string while the following columns indicate possible intervals that can be reached via lowering the mandals/orabs.

The first table contains the cent values and the second the just intervals, sometimes differing between ascending and descending ratios.

Any given configuration of mandal/orab positions, resulting in a certain set of pitches that can be played at a given time
(base for a maqam tetrachord) is represented by a choice of one cell in each row.

Inequal subdivision of the [[2187_2048|apotome (2187/2048, 113.7 cents)]] into 7 parts (8 mandals/orabs), in the following manner:
* Subdivision into one [[81_80|syntonic comma (81/80, 21.5 cents)]], one [[25_24|Zarlinian semitone (25/24, 70.7 cents)]] and another syntonic comma.
* Further subdivision of 25/24 into 65/64 (26 cents), 144/143 (12 cents) and 55/54 (32 cents).
* 65/64 and 55/54 are each split into two.

This gives the following interval positions of the mandals: 22, 13, 13, 12, 16, 16, 22 cents.
