Every ordinance shall be read in meetings of the council on three (3) different days. At each reading of an ordinance, it shall be open for discussion and amendment and may be referred to a committee, and shall be passed to the next reading unless, by a vote of the meeting, some other disposition is made. All ordinances that have been amended shall be engrossed, as amended, by the city clerk after the second reading. On final passage, the ayes and nays shall be called and recorded and a concurrence of a majority of all the members elected to the council shall be required for passage; provided, that three-fourths (3/4) of the members of the council may by aye and nay vote, recorded in the minutes, dispense with the three (3) readings of the ordinance and pass the same at one meeting.
