celiajoy I definitely have favorite inversions of chords. For me it's mainly a sound thing.
For me, some chords just sound better in inversions, & some chords the song will dictate which inversion to use. In some songs, the root or a particular inversion just won't sound "right" to the ear. Sometimes you're playing a chord in the melody, & then it has to be a certain inversion/position.
I do the same with the 7's. It's all how it sounds for me, but I do have my faves. I will always play a D7 with the C on the bottom, but a C7, I'll put the B on top or in the middle. Sometimes I just go with the closest inversion, & leave the 5th out because it will still have that 7 feel. I don't play a lot of jazz, but M7's for me always feel like they do best in root position, but there are some that can be done in inversions.
