The classical music form Dhrupad consists of how many structural parts, and how many parts does the Dhrupad proper song contain?

Explanation

2, 4. A Dhrupad performance is structured in 2 main sections (Alap and Song), while the song (Bandish) traditionally contains 4 parts: Sthayi, Antara, Sanchari, and Abhoga. Unlike Khayal (Amir Khusro, 13th Century) which has 2 parts, Dhrupad was patronized by Raja Mansingh Tomar in the 15th Century and reached its peak under Tansen (1506–1589) in the Mughal court.
