Consider the following statements in the context of Khayal or Khyal music: 1. The musical compositions of khyal are called qawwalis. 2. Poorabi is the slower variety of khyal and the Punjab style is the faster variety of khyal. 3. Origin of Khayal was attributed to Amir Khusrau. Which of the statements given above is/are correct?

Khyal and qawwali are two distinct musical forms. Khyal is a genre of classical Hindustani music that emerged in the late 18th century, while qawwali is a form of devotional music performed by Sufi musicians. Poorabi and Punjab are two different styles within the khyal genre, but their distinction is not based on tempo. Both styles can be performed at different speeds depending on the composition and the artist's interpretation. The distinction between Poorabi and Punjab styles lies in the melodic patterns, ornamentation, and overall aesthetic approach.
