Key Signatures in Music

The colored circle below represents the key signatures in music.  A key signature tells us how many sharps or flats are in a given piece of music.  There are 12 major keys and 12 minor keys for any music instrument and they are all the same.  For example, the orange G circle show that there is only one sharp for that key.

The key of G Major includes F sharp in its key signature.  That means that all F’s within that piece of music would automatically be F sharp every time it appears in the music.

Music Terms and Definitions


A Measure is the distance between 2 bar lines.  The bar line divides space on the music staff into measures.

Music Terms and Definitions

 Music Beat

A Music Beat is indicated by the time signature.  The 4/4 time signature below indicates four beats or four counts of sound per measure.  This example is also referred to as a Time Signature.

If the top number was 3, then there would only be 3 beats or counts of sound per measure of music.
