Which ancient Indian text is considered the foundation of Indian classical music?

  1. Rigveda

  2. Samaveda

  3. Yajurveda

  4. Atharvaveda


Correct Option: B
Explanation:

The Samaveda is one of the four Vedas, the sacred texts of Hinduism. It contains melodies and chants that were used in ancient Indian rituals and ceremonies.

What is the mathematical concept that underlies the structure of Indian classical music?

  1. Fibonacci sequence

  2. Golden ratio

  3. Pythagorean theorem

  4. Pascal's triangle


Correct Option: C
Explanation:

The Pythagorean theorem, which relates the lengths of the sides of a right triangle, is used to determine the intervals and scales in Indian classical music.

Which Indian mathematician and astronomer is credited with developing the concept of shrutis?

  1. Aryabhata

  2. Bhaskara II

  3. Brahmagupta

  4. Srinivasa Ramanujan


Correct Option:
Explanation:

Bharata Muni, the author of the Natya Shastra, is credited with developing the concept of shrutis, the 22 microtones that form the basis of Indian classical music.

What is the mathematical ratio that defines the perfect fifth interval in Indian classical music?

  1. 3:2

  2. 4:3

  3. 5:4

  4. 2:1


Correct Option: A
Explanation:

The perfect fifth interval, known as the 'pancham', is defined by the mathematical ratio of 3:2. This ratio is found in many natural phenomena and is considered pleasing to the ear.

Which Indian musical instrument is known for its intricate mathematical design and construction?

  1. Sitar

  2. Tabla

  3. Mridangam

  4. Veena


Correct Option: D
Explanation:

The Veena, a string instrument, is known for its complex mathematical design. The placement of the frets and the proportions of the instrument are based on mathematical principles to achieve specific musical intervals and tones.

What is the mathematical formula used to calculate the frequency of a note in Indian classical music?

  1. f = 2 * pi * sqrt(T)

  2. f = v / lambda

  3. f = 1 / T

  4. f = sqrt(T)


Correct Option: A
Explanation:

The frequency of a note (f) is calculated using the formula f = 2 * pi * sqrt(T), where T is the period of the wave.

Which Indian mathematician and astronomer developed the concept of the 'melakarta' system in Carnatic music?

  1. Aryabhata

  2. Bhaskara II

  3. Brahmagupta

  4. Srinivasa Ramanujan


Correct Option:
Explanation:

Venkatamakhin, a 17th-century musician and musicologist, developed the 'melakarta' system, which categorizes the 72 fundamental scales used in Carnatic music.

What is the mathematical relationship between the tonic and the dominant notes in Indian classical music?

  1. 4:3

  2. 5:4

  3. 3:2

  4. 2:1


Correct Option: B
Explanation:

The tonic and the dominant notes in Indian classical music are related by the mathematical ratio of 5:4. This ratio is known as the 'shadja-pancham' relationship.

Which Indian musical instrument is known for its logarithmic scale, which allows for precise tuning?

  1. Sitar

  2. Tabla

  3. Mridangam

  4. Sarangi


Correct Option: D
Explanation:

The Sarangi, a bowed string instrument, is known for its logarithmic scale. This scale allows musicians to tune the instrument precisely to different pitches.

What is the mathematical concept that underlies the rhythmic cycles in Indian classical music?

  1. Fibonacci sequence

  2. Golden ratio

  3. Pythagorean theorem

  4. Pascal's triangle


Correct Option: A
Explanation:

The Fibonacci sequence, a series of numbers where each number is the sum of the two preceding ones, is used to determine the rhythmic cycles in Indian classical music.

Which Indian mathematician and astronomer developed the concept of 'grahas' in Indian music?

  1. Aryabhata

  2. Bhaskara II

  3. Brahmagupta

  4. Srinivasa Ramanujan


Correct Option:
Explanation:

Bharata Muni, the author of the Natya Shastra, also developed the concept of 'grahas', the seven notes of the Indian musical scale.

What is the mathematical ratio that defines the perfect fourth interval in Indian classical music?

  1. 3:2

  2. 4:3

  3. 5:4

  4. 2:1


Correct Option: B
Explanation:

The perfect fourth interval, known as the 'madhyama', is defined by the mathematical ratio of 4:3. This ratio is found in many natural phenomena and is considered pleasing to the ear.

Which Indian musical instrument is known for its use of just intonation, where the intervals between notes are based on whole number ratios?

  1. Sitar

  2. Tabla

  3. Mridangam

  4. Tampura


Correct Option: D
Explanation:

The Tampura, a drone instrument, is known for its use of just intonation. This tuning system produces pure and harmonious intervals.

What is the mathematical relationship between the tonic and the subdominant notes in Indian classical music?

  1. 4:3

  2. 5:4

  3. 3:2

  4. 2:1


Correct Option: A
Explanation:

The tonic and the subdominant notes in Indian classical music are related by the mathematical ratio of 4:3. This ratio is known as the 'shadja-madhyama' relationship.

Which Indian mathematician and astronomer developed the concept of 'jati' in Indian music?

  1. Aryabhata

  2. Bhaskara II

  3. Brahmagupta

  4. Srinivasa Ramanujan


Correct Option:
Explanation:

Bharata Muni, the author of the Natya Shastra, also developed the concept of 'jati', the seven basic melodic structures in Indian music.
