Question

Assalamu alaykum wa rahmatullah 

I would like to have clarification about the reading speeds, as per  your recent explanation. What is the relationship between the three speeds your explained and two commonly mentioned reading styles "tartil" and "tajweed?" Are not these two styles too distinguished from their speed?

Answer

Wa alaikum assalaam wa rahmatu Allahi wa barakatuhu.

The terms “tarteel” and “tajweed” are not reading styles but intrinsic parts of recitation, but you have every excuse for thinking they were styles because the Qur’an tape sets often use these misnomers.  Reciting with tajweed means reciting the Qur’an using the rules of tajweed that we are learning here.  The term tarteel comes from the aayah: .  The translation of the explanation of the meaning is: ((And recite the Qur’an with measured recitation)) Al-Muzammil 4.  When Ali, may Allah be pleased with him, was asked about the meaning of “tarteel” he said, “ means tajweed of the letters, and knowledge of the stops.” 
As you can see then, tarteel and tajweed have nothing to do with the speed or style of recitation, instead they are the basics of recitation that all Muslims should apply when reciting the Qur’an. 

The term “tarteel” written on the side of some recitation tapes really refers to  as far as the slowest speed and fine tooth observation of the tajweed rules.  The same can be said about “mujawwad” written on some tapes also.  All known reciters use tajweed since it is the essential make up of reciting the Qur’an.
