Qalqalah (قلقلة) literally means "shaking" or "disturbance." In Tajweed, it refers to the slight bouncing or echoing sound that is produced when one of the five Qalqalah letters carries a sukoon. The five Qalqalah letters are memorized using the phrase قُطْبُ جَدٍّ: ق، ط، ب، ج، د. These letters share the characteristics of being voiced (Jahr) and having a strong, plosive quality (Shiddah), which causes a natural rebound when they are stopped abruptly.
Qalqalah is classified into three levels based on the position of the letter in the word. Qalqalah Sughra (القلقلة الصغرى, minor Qalqalah) occurs when a Qalqalah letter has a sukoon in the middle of a word, such as يَقْطَعُون (the ق has sukoon). Qalqalah Kubra (القلقلة الكبرى, major Qalqalah) occurs when a Qalqalah letter is the last letter of the word and you stop on it, such as stopping on الفَلَق. The major Qalqalah is more pronounced and noticeable than the minor one.
Some scholars also identify Qalqalah Akbar (القلقلة الأكبر, greatest Qalqalah), which occurs when a Qalqalah letter at the end of a word carries a shaddah and the reciter stops on it, such as stopping on الحَقّ or أشَدّ. In this case, the Qalqalah sound is the strongest and most noticeable.
A common mistake is adding a vowel sound to the Qalqalah — for example, making the ق in يقطعون sound like "qa" instead of a clean, short bounce. The Qalqalah should be a brief, clean echo of the letter without any discernible vowel. Our course provides extensive audio examples and interactive exercises to help you produce a clean, authentic Qalqalah at each level.
