How to tell which key a piece of music has modulated to?

Question

In a piece of music, when the key changes in the middle of the piece, how do you tell which new key this is?

Answer 1

because all keys have their relative keys. so for example. c has g and e etc.

i know the theory, but i need this funny oval graph to explain it :P there are acceptable key-changes within a key, unless you make some sort of industrial-music transition.

Answer 2

If you're listening to the music usually the dominant seventh of the new key is played before the shift. But not always. Often, the transition is a sudden thrust after a pause.

If you're reading the music you will see a double bar in the measure and then the new key signature.

Answer 3

The question could no longer be less demanding. And the respond can't be extra elusive. the least confusing answer could be to have a duplicate of the conductor's score and easily look at it. the subsequent least confusing technique is to (already) have a powerful experience of relative pitch and "meditate" on the recent tonal center. you will desire to be waiting to %. it out particularly without put off forward. each and every so often it facilitates to have an device or tone reference around to confirm your effect. yet there are additionally situations whilst song seems to modulate, nonetheless the composer will save the unique key, in simple terms which contain the fundamental accidentals. that's often achieved temporarily sections (like a bridge) of under a dozen measures and then the song returns returned "from whence it got here." ... I actually have a tough adequate time writing modulations, no longer to indicate reading them.
