256 Hz

B

64 Hz

C

32 Hz

D

512 Hz

Text Solution

Verified by Experts

The correct Answer is:
d
A series of notes arranged in such a way that their
fundamental frequencies have definite ratios is called a
musical scale. In 1588, Zarlino constructed a musical scale
by introducing six notes between an octave. These eight
notes constitute major diatonic scale. The first note or the
note of the lowest frequency is called keynote and ratio of
the frequencies of the two notes is called inerval between
them . It means two octaves higher means four times the
given frequency.
` therefore` Required frequency `= 4 xx 128 = 512` Hz
