About Dhwani (Sound) in Hindustani Music
In Hindustani Music, the concept of Dhwani (Sound) is the foundation of all musical creation. Not all sound is considered musical. The study of Dhwani involves understanding the distinction between general noise and the specific vibrations that create melody.
1. Definition of Dhwani
The word ‘Dhwani’ is derived from the Sanskrit root ‘Dhwan’, which means to sound or to echo. In general terms, anything that is heard by the ears is called Dhwani. It is produced by the vibration (Kampan) of an object.
2. Types of Sound
Broadly, sound is classified into two categories based on its nature and utility in music:
- Kolahal (Noise): Irregular, jarring, and unpleasant sounds that do not have a fixed pitch. These are not useful for music.
- Naad (Musical Sound): Regular, steady, and pleasant vibrations that have a definite pitch. This particular type of Dhwani is the basis of music.
3. Key Concepts
| Term | Meaning | Relevance |
|---|---|---|
| Vibration (Kampan) | Rapid movement of an object | Cause of all sound |
| Frequency | Number of vibrations per second | Determines pitch |
| Ahat Naad | Sound produced by striking | Used in practical music |
| Anahat Naad | Unstruck, eternal sound | Spiritual/Yogic concept |
