Musical Tuning Calculation

Calculates the height of notes of an instrument that is tuned with a defined musical tuning. The tuning describes the pitch of a reference tone, generally it refers to the concert pitch A4. The pitch of all other tones is derived directly from this one tone. For example, an octave difference means a doubling or halving of the pitch.
The normal tuning is 440 hertz for the standard pitch A4. Often, the tuning is 442 hertz, in former times, 435 and 415 were used or sometimes values notably higher than 440 hertz. Enter a tuning frequency and choose a note from the list or enter a norm frequency. The norm frequency is the height of a note respective to the 440 Hz of A4. The frequency for the chosen tuning will be calculated.

The formula for the calculation is: frequency = norm frequency * tuning / 440 Hz

Example: C6 has a norm frequency of 1046.5 hertz. At a tuning of 420 hertz, this has a frequency of 998.93 Hertz.

Instruments don't have to be tuned to 440 hertz, but can also have a higher or lower pitch. Historical tunings are often lower. Lower tunings often sound darker or more serious, while higher tunings are perceived as more cheerful and upbeat. Therefore, tuning instruments lower is also common in modern music to achieve a corresponding effect. However, tuning is only one aspect of the perception of music, there are many others, like scales for example.
Another aspect of tuning, not considered here, is the spacing of the playable notes on an instrument. There are a wide variety of options here, the tuning systems. Well-known tunings, for example, are well-tempered tunings, which make all keys of the circle of fifths playable.
