[[Al-Farabi]], Persian scholar of the 10th century, distinguished tonal duration. In one of his four schemes, in his two-volume ''[[Kitab al-Musiki al-Kabir]]'' (''Great Book of Music'') he identified five classes, in order of ranking, as follows: the human voice, the bowed strings (the ''rebab'') and winds, plucked strings, percussion, and dance, the first three pointed out as having continuous tone.

[[Ibn Sina]], Persian scholar of the 11th century, presented a scheme in his ''Kitab al-Najat'' (Book of the Delivery), made the same distinction. He used two classes. In his ''[[Kitab al-Shifa]]'' (Book of Soul Healing), he proposed another taxonomy, of five classes: [[fret]]ted instruments; unfretted (open) stringed, [[lyres]] and [[harps]]; bowed stringed; wind (reeds and some other woodwinds, such as the flute and bagpipe), other wind instruments such as the organ; and the stick-struck santur (a board zither). The distinction between fretted and open was in classic Persian fashion.
