Do songs stay in the same key?

Some songs stay in the same key all the way through, and some songs change keys. Or it could start in C major but incorporate chords borrowed from other keys, use melody notes outside of the notes in the C major scale, or it could leave the key of C major entirely at one point, only to return to C major before it ends.

How do you know if songs are in the same key?

Probably the easiest way to determine what key you're in is when the written music tells you the key. In this example, one flat means that the song is in F. F# and Gb are the same key, just with a different name (and different names for each of the notes).

Does every instrument in a song have to be the same key?

If a song is in a certain key, can you add an instrument or vocal to the song / track as long as they are in the same scale of that key. So for example, if a song is in key D major, you can add any instrument/vocal as long as the key is in the D major scale, so E minor, B minor, G Major, A Major, etc, etc.

Can songs be played in any key?

Theoretically you can play any melody and chord progression for a song in any key. But a song will often work best in certain keys and usually the key it was written in for a specific instrument.
