How do I figure out what key a song is in?

Looking through the key signature on sheet music is the quickest and most straightforward approach to determining the key of a song. If its key signature is missing from the sheet music, you will either need to examine the notes used or chords in the song to determine the key.

How do I find the scale of a song?

Consider the song’s notes and attempt to determine if they are from a major or minor scale. The notes used in both scales are the same, although they begin in different locations.

You’ll be able to recognize the scale if you can see bits of one of these scales. You may also focus on the song’s opening and closing notes.

How do you identify key signatures?

The note one-half step (semitone) above that last sharp is the key signature. Major and minor keys may be mentioned in key signatures. Get the name of the major key, then count back three half steps (a tone and a semitone) to find the name of the minor key. Recall that names are impacted by sharps and flats.
