I find most of my chord progressions just by doing a Google search with the name of the song followed by “chords” but if that is not helpful I use an app called Chordify. You can search YouTube and it will analyze any song there and display the chords in a logical progression that lets you know how many beats etc.
Owen, thanks for that tip about chordify. I’m going to give it a try. I hear songs I like on YouTube often and since I’m still new to the music scene, I have trouble identifying the key and the chords.
