What creates a key change in music?

What are key changes in music?

A key change is often the climax in a song, and thus usually comes into play later on, after the listener has heard the chorus in its original key a few times.

What is it called when a piece changes key?

Modulation, in music, means that the music changes key. A piece of music might, for example, be "in the key of C major" (meaning that it uses the notes of a C major scale, and the C sounds like the "home key" or "tonic" as it is called in music theory).

How can change of keys be identified in music?

The way to change keys with the chromatic scale is to walk up (or down) until you reach the root note of the new key. So if you want to change the key from G major to B major, you can use this walkup: G – G♯ – A – A♯ – B.
