Q: im confused about note/note chords. would c/e be e c e g (normal c chord with an extra e below it)or e g c (flipped version of c chord)?
A: i would say if your chart says C/E, that means the E note is probably supposed to be a bass note. (so, probably at least an octave away from the rest of the chord. As for whether you think it's necessary to still include another E note in the midrange part of the chord, that's up to you. it can be nice to put the E in the bass and actually just play C and G in the midrange of the chord. that's a pretty nice sound that is found readily all over all types of music you've heard. you'll have to check to see which seems to sound better at that point in the song you're playing, and on the instrument you're using. If the arranger has a specific preference, then they're gonna have to tell you directly or else write out the notes in the chart
