Concept:Every raga in Hindustani classical music belongs to one of the ten basic thaats (parent scales). Raag Yaman is a heptatonic raga that derives from the Kalyan Thaat.
Explanation:According to Vishnu Narayan Bhatkhande, the ten thaats are Bilawal, Kalyan, Khamaj, Bhairav, Poorvi, Marwa, Kafi, Asavari, Bhairavi, and Todi.
In Kalyan Thaat, all notes are shuddha (natural) except the fourth note (Ma), which is teevra (sharp).
Raag Yaman uses all seven notes: Sa, Re, Ga, Ma (teevra), Pa, Dha, Ni — exactly matching the scale of Kalyan Thaat.
Therefore, the thaat of Raag Yaman is Kalyan.
