Question

A rhythm pattern is given as "^56 v25 Mn". Which of the following is the correct beat emission pattern?

(A) 56 25
(B) 5625
(C) 56x25
(D) 56:25

Answer 1

The correct beat frequencies when notes A and C are played together is 44 Hz, and when notes D and F are played, it is 55 Hz. When all four notes are played together, both these beat frequencies along with other combinations would be present.

Step-by-step explanation:

Beat Frequency

To determine the beat frequencies when musical notes are played together, we subtract the frequencies of the two notes. The beat frequency is the difference in the frequencies of the sounding notes, which can be heard as a pulsation or beating in the sound.

• (a) For notes A (220 Hz) and C (264 Hz), the beat frequency is 264 Hz - 220 Hz = 44 Hz.
• (b) For notes D (297 Hz) and F (352 Hz), the beat frequency is 352 Hz - 297 Hz = 55 Hz.
• (c) When all four notes (A, C, D, F) are played together, the beat frequencies present would be the absolute differences between each pair, namely 44 Hz (between A and C) and 55 Hz (between D and F), as well as the other possible combinations resulting from the mixed frequencies.
