The idea that photography “freezes a moment in time” means what?

You remember the moment it something memorable

It depends on what type of third separates the three notes.for example: if you have two mayor thirds is an "aumented chord"if you have two minor thirds is an "diminued chord"if you have one mayor first and then one minor is a "mayor chord"and inverted is a "minor chord"

That is true  i hope that : )
