One of the underrated features of the BYU experience is listening to the Carillon Tower play at certain times of day. A friend of mine had access to it and showed us the tower where the carillon is--it is impressive and would take some skill to play.
Mormonism is deceptive and false. Do not add to the bible and teach that stuff to unsuspecting people. John Smith and people called prophets up to this day in the mormon church are false prophets. There is no secret knowledge in the mormon church, just ear tickling dangerous doctrine that takes away from the fact that Jesus Christ payed it all on the cross and works will not get us into heaven but a personal relationship with him in faith and repentance.
The bells often play a line from the Mormon hymn 'Come, Come Ye Saints' on the hour.
