Hi karin.lam69,

When you're changing chords, the strings stop ringing. I'm not entirely sure what that means, but if you lift your fingers off the strings to change into another chord, then yes, the sound of that previous chord will stop ringing.

Gary has a great lesson on chord changes right here: https://www.guitartricks.com/lesson.php?input=28910

Let me know if that helps!
