Hi @angelo, thanks for writing!
The following applies to the 1357 system you’re using, as well as the other common left hand voicings.
If you move the chords in 25s (or in cycle of 5ths in general) with good voice leading (meaning voices stay put or move mostly in half/whole steps),
they tend to move downwards. They key is, once you move too low, you can jump up few inversions, depending on what kind of sound you’re looking for, and/or what the right hand is doing.
Have you checked out the following left hand voicings?
In general, you need just these voicings to survive almost any musical situation, as if one inversion goes too low, you have the other one to use! Also these voicings have little more color in them that supports the color of the 251 (major or minor).
Also, please check out Hayden’s awesome course on left hand voicings:
Thanks, let me know if you have any further questions,
