If you had a Touch Tone phone, you could hold any button while on a call and the noise would annoy sales callers, or the creepy heavy breathers that would call.
Also, each button was a combination of 2 frequencies, each row and each column had a certain frequency. So, each button was a combination of those two.
But, if you pushed two buttons on the same row, or two buttons in the same column, you could get a single “note”. So, you could play very basic tunes.

That still works with modern phones no?
Cell phones only register a momentary tone. Landlines (POTS) still do this though, yes.
