Q: Or it's a feel-along excercise with the theory behind the played voicings being an afterthought to analyze what was done? Upon
  yet ano
 ther revision my last version would be Ab (207.65) and on right hand g(392)-bb-c=eb which would translate to Abmaj7add9, and then for second chord Bb on bass (233) and then on right hand f(349)-bb-c-d. which would be a Bbadd9. Does it sound like a more balanced voicing?
A: that seems great but very much on the high side. your bass notes are around middle C. this is cool, but if you are generally in the meat of the arrangement, your bass notes are going to be an octave lower (probably 2) and the right hand parts would be maybe half an octave lower. i'd say a nice happy range for your first chord (speaking in Hz again, cuz it's the only way to truly say which octaves we're using) Ab 52, and chord would start from Bb233 and up. a good range for the other one would be Bb 58, and C D F starting from middle C and up.
