We have seen in the previous lesson al the major triads in close (or closed) position. As already stated if these notes of the triad (or ‘voices’) are contained within an octave we call it in ‘close’ or ‘closed’ position, as opposite as ‘spread’ position (more than an octave). Just watch the video where I go through all the most popular shapes for the latter.
Just like for the close position, it is really simple to find other (minor, augmented, diminished) triads from the major triad.
Major triad – R,3,5 – C,E,G
Minor triad – R,m3,5 – C,Eb,G (Lower the 3rd one 1/2 step)
Augmented triad – R, 3, #5 – C,E,G# (Raise the 5th one 1/2 step)
Diminished triad – R,m3,dim5 – C,Eb,Gb (Lower both the 3rd and 5th one 1/2 step)
