Nigger, how do you form the different seventh chords from major, and what's the difference between each type?In all srsness, a seventh chord of any type differs from a major or minor in that it necessarily has at least four notes (I-III-V-VII) rather than a triad (I-III-V).
A regular seventh chord is tonic, major third, perfect fifth and diminished subtonic. In other words, I-III-V-VIIo. G-B-D-F would be a 7th chord.
A major 7th (not the same) would be tonic, major third, perfect fifth and diminished octave. This would be I-III-V-Io. In the key of G, this would be G-B-D-Gb.
Finally, a minor 7th would be tonic, minor third, perfect fifth and diminished subtonic. This would be I-iii-V-VIIo. In the key of G, this would be G-Bb-D-F.
Note that it's more common to play a chord as I-V-VII-III rather than the value in order of size on guitar, which is essentially a major chord without the root's octave, instead replaced with a diminished 7th. If that makes any sense. As such, played on guitar, a regular 7th would be G-D-F-B, a major 7th would be G-D-Gb-B, and a minor 7th would be G-D-F-Bb.
