Learning To Read Music Tutorial 2

Description

If a piece of music (or a whole section) is in one key signature and changes to another there is a proper procedure to follow to indicate this change.

First, a double bar line is drawn. Next, the new key signature is indicated before any other notes happen. In the example, we are in the key of G major with its one sharp indicated on the F line. But then we change to F major which is indicated by a flat symbol on the B line (since the only accidental in the key of F major is B-flat).
