Thaat in Hindustani Music6 min read

10 Thaat in Hindustani music are the ten parent scales from which most ragas are derived.
A thaat in music is a group of seven notes arranged in ascending order that forms the foundation for many ragas.

In simple terms, thaats are like “families” of ragas. Each raga belongs to a thaat based on the notes it uses.

What is Thaat in Hindustani Classical Music?

In Hindustani classical music, a thaat is a framework of seven notes (Sa, Re, Ga, Ma, Pa, Dha, Ni) arranged in order. The concept of the 10 thaat system was introduced by musicologist Vishnu Narayan Bhatkhande to organise ragas in a systematic way.

Each of the 10 thaat has a specific combination of natural (shuddh), flat (komal), or sharp (teevra) notes. From these parent scales, many beautiful ragas are created. For example, Raga Yaman comes from the Kalyan thaat.

Why is the 10 Thaat (Parent Scale) System Important?

• Creates Structure in Learning
  The 10 thaat system helps students understand how ragas are grouped and organised.
• Builds Strong Musical Foundation
  When children learn thaats, they understand note variations clearly.
• Improves Raga Recognition
  Knowing the parent thaat helps students identify ragas more easily.
• Develops Listening Skills
  Children start hearing the difference between shuddh, komal, and teevra notes.
• Encourages Logical Understanding
  Instead of memorising ragas randomly, students learn them through patterns and relationships.

List of 10 Thaat in Hindustani Music

Below are the ten parent scales recognised in the Bhatkhande system.

1. Bilawal Thaat

All seven notes are shuddh (natural).

Example: Raga Alhaiya Bilawal

Bilawal is considered the base scale and is similar to the Western major scale.

2. Kalyan Thaat

Ma is teevra (sharp), all other notes are shuddh.

Example: Raga Yaman

Kalyan thaat sounds bright and uplifting.

3. Khamaj Thaat

Ni is komal (flat), all other notes are shuddh.

Example: Raga Khamaj

Often used in light classical music like thumri.

4. Kafi Thaat

Ga and Ni are komal.

Example: Raga Bhimpalasi

Kafi has a soft, expressive feel.

5. Asavari Thaat

Ga, Dha, and Ni are komal.

Example: Raga Asavari

This thaat creates deep and serious moods.

6. Bhairav Thaat

Re and Dha are komal.

Example: Raga Bhairav

It is often sung in the early morning and has a devotional mood.

7. Bhairavi Thaat

Re, Ga, Dha, and Ni are komal.

Example: Raga Bhairavi

Very popular and widely used in classical and semi-classical music.

8. Poorvi Thaat

Re and Dha are komal, Ma is teevra.

Example: Raga Puriya Dhanashree

This thaat creates a serious and intense sound.

9. Marwa Thaat

Re is komal, Ma is teevra.

Example: Raga Marwa

It creates tension and is usually sung in the evening.

10. Todi Thaat

Re, Ga, and Dha are komal; Ma is teevra.

Example: Raga Miyan ki Todi

Todi has a very distinctive and emotional character.

10 Thaat and Their Note Structure

In Hindustani classical music, a thaat is a parent scale consisting of seven notes (swaras) arranged in ascending order. Pandit Vishnu Narayan Bhatkhande classified ragas into 10 primary thaats based on their note structure.

*Although Khamaj thaat includes Komal Ni, many ragas use Shuddha Ni in ascent and Komal Ni in descent.

How to Practise 10 Thaat 

Understanding thaats is easier when children practise actively instead of only memorising.

For Beginners at Home

• Start by learning the seven basic swaras.
• Clap and say the note names while ascending.
• Listen to one raga from each thaat and identify the mood.
• Use comparison: Ask your child, “Does this sound bright or serious?”
• Avoid rushing through all ten at once. Learn 2–3 first.

Parents do not need musical training to help. Just listening together and discussing the mood builds understanding.

For Singers

• Sing the aroha (ascending scale) slowly for each thaat.
• Focus on identifying which notes are komal or teevra.
• Practise with a tanpura or shruti box for correct pitch.
• Compare two thaats (e.g., Bilawal vs Kalyan) and notice the difference in Ma.
• Sing simple alankars using each thaat.

For Instrument Players (Piano, Guitar, Ukulele, Keyboard)

• Play each thaat as a scale slowly in ascending order.
• Identify the altered notes on your instrument.
• Practise switching between two similar thaats to hear differences.
• Use a drone note (Sa) while playing.
• Try creating a simple melody using notes from one thaat only.

Common Mistakes with 10 Thaat & Quick Fix

• Mistake: Memorising without understanding note changes
  → Quick Fix: Always identify which notes are komal or teevra.
• Mistake: Confusing raga and thaat
  → Quick Fix: Remember, thaat is a parent scale; raga is a melodic form.
• Mistake: Ignoring pitch accuracy
  → Quick Fix: Practise with a tanpura or keyboard reference.
• Mistake: Learning all ten at once
  → Quick Fix: Learn gradually in small groups.
• Mistake: Not listening to real examples
