Hi, i did the all caps voice question two seconds ago. So it seems that you voice chords according to melody and comfort of your hand. So with that logic a 1,4 ,5 blues in E, the notes would be like for E7=E,G#,B,D, A7=E,F,G,C#, and B7=D#,G#,A, B? WHY IS LIFE SO HARD
A7 usually won't have F unless it is marked A+7, or if F is in the melody. also when in doubt, in 7th chords just stick to the 2 notes that form a tritone. so in E7 that's D and G#. and when in doubt play them in the octave around middle C
