Question

Choose the correct options of staff notation system of the following: \[ \text{A. The sign of flat note } \sharp \] \[ \text{B. The sign of sharp note } \flat \] \[ \text{C. The sign of crotchet } \quarternote \] \[ \text{D. The sign of Semibreve } \bigcirc \] \[ \text{E. The sign of double sharp } \times \]

• A. C, D and E only
• B. A, B and C only
• C. B, C and D only
• D. A, C and D only

Hint:

Sharp sign is \(\sharp\), flat sign is \(\flat\), and double sharp is commonly shown by \(\times\).

Answer 1

The Correct Option is A

Concept:
In Western staff notation, every note and accidental has a specific symbol. Flat and sharp signs are different.

Step 1: Check flat sign.
The flat sign is: \[ \flat \] But statement A gives: \[ \sharp \] So, A is incorrect.

Step 2: Check sharp sign.
The sharp sign is: \[ \sharp \] But statement B gives: \[ \flat \] So, B is incorrect.

Step 3: Check crotchet, semibreve and double sharp.
Crotchet is represented by a quarter note symbol. Semibreve is represented by an open oval notehead. Double sharp is represented by: \[ \times \] Thus, C, D and E are correct.

Step 4: Final conclusion.
The correct statements are: \[ C,\ D,\ E \] Hence: \[ \boxed{\text{(A) C, D and E only}} \]
