Q: These are the tajweed rules I know. Please tell me if they are correct and if there are any more.
Ghunna – Nasal sound
Idghaam Meem Saakin – Nasal sound
Idghaam – Nasal sound
Qalb – Nasal sound
Qalqala – jerk or bounce when stopping at certain letters
Ikhfa Meem Saakin – light nasal sound
Ikhfa – light nasal sound
Does the 2 Ikhfas have to be light or can it be like the others (Heavy Ghunna)?
Idghaam does not always have to be a nasal sound.
Jerk may not convey the exact meaning of qalqalah. You may say that is a rebounding sound.
The other explanations seem to be correct.
And Allah Ta’ala (الله تعالى) knows best.
