... or from anyone who has an insight before I get lost. I've been practicing a "Key of the Week" (which has become a key every three weeks) and one of the things I have been doing is working through voicings of the chords within the key: I chord, ii chord, iii, chord...etc. Simple enough. I am also practicing jumping from the 1357 voicing to a closed voicing (7935). So here is what I'm noticing: when I voice the 1357 of the minor chord, the Abm7 in Gb, B and E for example, it voices the same way as a ii, iii, or vi. But when I voice it as a 7935 the added ninth can be different (????).
