An octave is a sequence of 12
notes, given by the recurrence relation:
with and starting from the note
with
.
The following table is an octave table (sequence of pitches) with notes corresponding to frequencies. Each successive frequency is determined by multiplying the previously obtained frequency with .
Note | Frequency (Hz) |
---|---|
![]() | 440.00 |
![]() ![]() | 466.16 |
B | 493.88 |
C | 523.25 |
![]() ![]() | 554.37 |
