Why was meeting Sabri Mudallal in the Great Mosque of Aleppo so highly regarded by the author of the chapter?

What will be an ideal response?

• "Sabri Mudallal's voice is well known as the ‘first muezzin' [‘first caller'] of the Great Mosque [the Zakariyya Mosque]" where he broadcasts the Islamic Call to Prayer (called Adhan; also called Azan in English). The Call to Prayer is delivered by muezzins at five designated times each day from the minarets of mosques.
• While this is a powerful musical rendering of a sacred Islamic call to prayer; the focus is on the devotional intent of the event, not the musical talent of the reciter.
