It seems that for the first century or so in al-Andalus,  were brought west after being trained in Medina or Baghdad. They might also have been trained by artists from the east. In the 11th century the Caliphate of Córdoba collapsed. At that time,  were often trained in Córdoba rather than imported after training. It seems that while female singers still existed, enslaved ones were no longer found in al-Andalus in the 14th century CE.
