Web1 jun. 2024 · In music theory, the usual definition is 12 notes in each octave, going up an octave doubles the frequency, and A4 is defined as 440 Hz. It is also important to note that the notes are spread evenly in an octave. Using this definition we can write a function that when given a frequency returns the note and the octave. WebThe range between 40 and 80 Hz and the range between 4000 and 8000 Hz both constitute an octave. The same interval can be expressed as a ratio in two different ways, but the higher figure is always the high tone. If, for example, the ratio of a fifth is expressed as 3/2 instead of 2/3, the cent value becomes negative ( one fifth down , or -702). chris weerts tucson az
