Note Ratio

Calculates the ratio of the tone pitches of two notes at an equal temperament.Then, an octave has twelve notes with equal sized half step distances from each other. The equality of the steps refers to the ratio, not to absolute values. The pitch ratio of two neighboring tones ist the twelfth root of two. Between any two tones, the ratio is ¹²√ 2ⁿ , where n is the interval size.
The frequency of a tone can be taken from the tuning calculator. Please enter an interval and select, if the calculation should be done upwards or downwards. Optionally, enter a frequency. The ratio will be calculated and, if a frequency is given, the new frequency.
