Beat Frequency: How Does it Change With Pure Tone Increase?

[T@P]

if i play two pure tones together, i create a beat frequency. if i increase, any of the two pure tones, what happens to the beat frequency?

heres my logic as to why the beat frequency can go either way: Fb = F1-F2, so if you increase F1 it increases and the opposite if you increase F2.

how wrong am I?

T@P,

you are correct.

In other words, it is a matter of whether changing the frequency of one note moves the frequencies close together or further apart.
