Was turned onto this group recently.....liking this group's "soul". In the short time I've been playing, part of my fun has been training the ear to correctly nail down a song's key w/o checking online tab. Am successful much of the time but get stumped now and again. This song is an example.....a simple song with a repeated progression of Gmaj, Fmaj, and Cmaj. My ear says G major with a borrowed Fmaj chord but online sites say C major.....not that it matters really, but I think a budding guitarist ought to at least be able to nail down a 3 chord song. What do you veteran players say.....C major or G major?
