Since my article on the above appeared, additional information has come to hand which appears to be of sufficient merit to be recorded, more especially because this old music of the Moors is gradually disappearing. At the invitation of the Egyptian Government, I attended a Congress of Arabian Music which was held in Cairo during March and April, 1932, where I had the honour to preside over the Commission of History and Manuscripts. During this congress I had the opportunity of studying, at first hand, the practical as well as the theoretical art. The best native orchestras from Arabic speaking lands were in attendance, and among them were three from Morocco, Algeria, and Tunisia. These latter included in their répertoires the old Maghriban melodies from the ṭubū', naubāt, or ṣan'āt. At these auditions, and from conversations with the musicians, but more especially through information obtained from Sīdī Ḥasan 'Abd al-Wahhāb the Governor of Mahdia, and Sīdī Muḥammad al-Manūbī al-Sanūsī of Tūnis, I had confirmation by eye and ear of that which hitherto had only been known to me by script.
