I was watching this video of I've got no strings.
I was wondering if I'm correct in thinking that the song's verse is in G major but then modulates to its relative minor, E minor during the "Hi-ho the me-ri-o That's the only way to go" that happens in 0:15 of that video.
sadder more serious all of a sudden and that's why I think there's a modulation even though it still uses the same notes. One could say the Em chord is just the 6th diatonic chord of G major, but I'm thinking it's a modulation to E minor because the character of the song changes. Is it in fact a modulation to E minor and how could you tell?
