It is meant to be a beautiful, melodic and spiritual start to the day.
But the morning calls to prayer by some of Istanbul's muezzins and imams have had locals plugging their ears rather than reaching for their prayer books.
The problem is such that following a flood of complaints by locals, special classes for the tuneless culprits have been set up.
Imam Mehmet Tas, one of the school's first pupils, said he was already feeling the benefits.
"I have so much more self-confidence now in my abilities to do all five calls to prayer in their correct tempos," he said.
The improvement scheme was put together by Mustafa Cagrici, the city's head of religious affairs, who is determined to make sure all of the city's 3,000 mosques produce a beautiful call-to-prayer each morning.
"For some reason, these imams were hired even though their voices are not good, they just can't sing!
"We're doing our best to help our imams and muezzins to improve their singing."
He says that since lessons started, complaints have dropped from hundreds a month to just dozens, an improvement that can be credited to the singing teacher, Seyfettin Tomakin.
"I personally find a badly sung azan [call to prayer] very disturbing," he said.
"The azan is music, beautiful music that brings people to God, that's why it's so important to sing it well.
"Sure, there are some people who find it harder than others, that's why some come here for a year. But my job is to find their voice to enable them to sing."
Sadly, for some, no amount of teaching will ever be enough.
"There are some people who can't improve - no matter how much training you give them," said Mr Cagrici.
"So we connect their mosque, by radio, to a central mosque where there's an imam who can sing."
uhhmm...teringat kisah Bilal bin Rabah di zaman Rasullullah S.A.W...anyone willing to share..?coz xbape igt jalan criter..maybe boleh jadi kn iktibar utk kita...
kalau kat malaysia buat mcm tu jgk bgus laa...azan tu kalau di laung sebaik baik nya merdu sgt..tapi kebanyakan bilal2 kat surau2 alahai..macam surau kat rumah aku ni..kalau buat teguran satgi leh jadi pergaduhan..silap2 kena pulau..dah la x sedap kuat pulak tu..subuh2 tu agak2 laa.ini dia on mic ja terkejut weh...kena hormat org bukan islam jgk..apa pun bunyian yang pakai sistem bunyi ni kalau kuat sgt akan jadi gangguan walau azan sekalipun...kalau yang islam tu faham la kan bagi yang bukan islam macam mana..x kan nak paksa suruh dia org dgr gak azan..
azan yang sedap di dgr menyaman kan jiwa so elok la sesiapa yang jadi bilal belajar azan cara yang betul dan lenggok yang betul..
bila la nak buat kat msia...kepada yang sumbang tu, nak tegur salah, nanti orang cakap menghina azan lah pulak...at least imam kat kariah aku ni ade la juga kemajuannya, surah pun dah lagu al afasy sekarang ni...
yang penting tajwid betul baru makna tak lari, kalau setakat sedap kat telinga tapi makna sebenarnya tak betul nak buat apa? azan tu memanggil org2 yg beriman utk ingat Allah bukan sekadar nak sedap didengar. kalau betul tajwid insyaAllah sedap didengar. Yang x sedapnya kalau tajwid x betul
masa aku kat sek menengah, ada sorg brother ni, selalunya dia amik turn azan solat subuh, masyALlah, mendayu-dayu...sooodaaap sgt sore dia...
tp dia dah jd arwah masa umor 30 thn, meninggal dlm tido..heart attack doc cakap....al-fatihah utk abg aku tu...
