Question

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). \[ \text{Assertion (A): Stable Swara instruments like Harmonium, Piano, Organ etc. cannot be tuned by the equally tempered scale.} \] \[ \text{Reason (R): Whole Saptaka is divided in 12 equal parts in the equally tempered scale.} \] Choose the most appropriate answer from the options given below:

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A)
• B. Both (A) and (R) are correct but (R) is not the correct explanation of (A)
• C. (A) is correct but (R) is not correct
• D. (A) is not correct but (R) is correct

Hint:

Equal temperament divides the octave into \(12\) equal parts and is commonly used for fixed-pitch instruments.

Answer 1

The Correct Option is D

Concept:
The equally tempered scale divides the octave into 12 equal semitones. This system is widely used in fixed-pitch instruments like piano, harmonium and organ.

Step 1: Check Assertion (A).
The assertion says that stable swara instruments like harmonium, piano and organ cannot be tuned by the equally tempered scale. This is not correct. Such fixed-pitch instruments are commonly tuned using the equally tempered scale.

Step 2: Check Reason (R).
The reason says that the whole Saptaka is divided into 12 equal parts in the equally tempered scale. This statement is correct. \[ 1 \text{ octave} = 12 \text{ equal semitones} \]

Step 3: Final conclusion.
Assertion is incorrect, but Reason is correct. Hence: \[ \boxed{\text{(D)}} \]
