First dawr: a melody that may include tarannum or not. When it does not, it is limited to one or two lines of poetry.
Second dawr: a repetition of the first dawr with different lyrics. If the first dawr includes a tarannum, then so does the second one. If the first
dawr does not include a tarannnum, then neither does the second one.
Khāna or māyt khāna: another melody with new lyrics. It can either be equal in length to one of the adwār, or double its length,
thus equal in length to both put together. Also, if both adwār include a tarannum, then this tarannum is repeated at the end of the
khāna‘s melody. If they do not, then a tarannum is composed especially for the khāna, improvised by the performer, or bypassed to go
directly to the khātima (conclusion). Usually, the khāna’s melody allows for responsorial passages between the munshid (performer) and the
biṭāna, i.e. the improvisation resulting from the khāna’s melody followed by the taslīm in repeating part or all of the
khāna as a pre-conclusion.
The khārija: the repetition of the first dawr’s melody –that is the same as the second’s– with new lyrics. The melody is either repeated
in full –which is the usual process–, or repeated partially –in some exceptions– then considered as a conclusion to the piece.
