Q: really interesting conversation starting about this stack voicing/dense chord topic. okay so here's a voicing that I personally think sounds quite alright when stacked on top up an octave (keep in mind needs to be played in the mid/upper range of the keyboard). the voicing is A-B-D-F#. what different notes would you add to reinforce this boy here?
A: you didn't tell me exactly what octave that's in. every octave is completely different, if you're talking about chords (multi-note)
