When you are accompanying someone, you are listening to them the way you listen to a Bach Chorale, where four parts are going on at the same time, all of which are gorgeous melodies, all being played simultaneously. ↗
If you can say the lyrics almost like a poem and they stand up, that's a great thing. Some songs have great lyrics and I don't like the melodies, and vice versa. ↗
But my role is to just apply the skills I've learned over the years: you listen to the guitar, you listen to the vocal melodies, you listen to the rhythm, and you come up with something that helps you take the song somewhere. ↗
In country music the lyric is important and the melodies get a little more complex all the time, and you hear marvelous new singers who are interested in writing and interpreting a lyric and in all form of popular music. ↗
