So I've been using the metronome to focus on chord changes and playing scales. How do I use the metronome to learn a certain song? lets say I know the song is 145 bmp. Take this tune for example : https://www.youtube.com/watch?v=NW2lQV6z05M . How does one use a metronome to learn that tune? how would I break up a song and learn it with a metronome?
