5. New frequency = 659.26Hz

6. Interval = 700cents

Did this calculator solve your problem today?

The math behind it

new frequency = start x 2^(semitones / 12). Twelve semitones make an octave (double the frequency).

440 Hz up 7 semitones (a fifth) is about 659.3 Hz.

What is a cent?

1/100 of a semitone, used for fine tuning.
