Is famous way of saying تلبية correct? The famous way of how they melodize it & they stop at „لك والملك“ & „والنعمة“ & „ إن الحمد“ Or neither stop nor beautify voice? Also what is meant with تلحين ? For example for Adhān it is said to do تحسين of your voice but not تلحين, what is the difference?

Ustadh AbdulAziz al-Haqqan

Saying it in unison and in the way you described is incorrect, you can just normally say it without any of this.
