Qawwali - Musical Structure

Musical Structure

Songs are usually between 15 to 30 minutes long. However, the longest commercially released qawwali runs slightly over 115 minutes (Hashr Ke Roz Yeh Poochhunga by Aziz Mian Qawwal). The qawwali maestro Nusrat Fateh Ali Khan has at least two songs that are more than 60 minutes long.

Qawwalis tend to begin gently and build steadily to a very high energy level in order to induce hypnotic states both among the musicians and within the audience. Songs are usually arranged as follows:

1. They start with an instrumental prelude where the main melody is played on the harmonium, accompanied by the tabla, and which may include improvised variations of the melody.
2. Then comes the alap, a long tonal improvised melody during which the singers intone different long notes, in the raga of the song to be played.
3. The lead singer begins to sing some preamble verses which are typically not part of the main song, although thematically related to it. These are sung unrhythmically, improvised following the raga, and accompanied only by the harmonium. After the lead singer sings a verse, one of the side singers will repeat the verse, perhaps with his own improvisation. A few or many verses will be sung in this way, leading into the main song.
4. As the main song begins, the tabla, dholak and clapping begin. All members join in the singing of the verses that constitute the refrain. The lyrics of the main verses are never improvised; in fact, these are often traditional songs sung by many groups, especially within the same lineage. However, the tunes are subtly improvised within the framework of the main melody. As the song proceeds, the lead singer or one of the side singers may break out into an alap. Nusrat Fateh Ali Khan also popularized the interjection of sargam singing at this point. The song usually builds in tempo and passion, with each singer trying to outdo the other in terms of vocal acrobatics. Some singers may do long periods of sargam improvisation, especially alternating improvisations with a student singer. The songs usually end suddenly.

The singing style of qawwali is different from Western singing styles in many ways. For example, in words beginning with an "m", Western singers are apt to stress the vowel following the "m" rather than the "m" itself, whereas in qawwali, the "m" will usually be held, producing a muted tone. Also in qawwali, there is no distinction between what is known as the chest voice and the neck voice (the different areas that sound will resonate in depending on the frequency sung). Rather, qawwals sing very loudly and forcefully, which allows them to extend their chest voice to much higher frequencies than those used in Western singing, even though this usually causes a more noisy or strained sound than would be acceptable in the West.
