al-Dîn points out that firstly he determines seven tones in the first
tetrachord on the bamm string of the ûd with ratios of "the second
doubling kind" (9/8x9/8x256/243=4/3 tone-tone-limma), which he calls
"zül-müddeteyn", then as limma-limma-tone 9/8x9/8x256/243=4/3
He doesn't perform the duty to find the others, just points out the names
of tones. The tones he determined is shown on a table of the ûd with
their high in pitch octaves in Kitâb al-Adwâr
and al-Sharafiyyah like this (21):

al-Dîn shows the tunes on the strings after the bamm by giving the
names. However, he tells in his Kitâb al-Adwâr the division
of an octave into 17 intervals in detail |

this manner is carried on in the works of following Adwârs and new
works. (22)
These 17 tones (18 with its octave) are shown depending on their distance
to the starting sound like this: |
