How to play C#m7 on bass
Low notes close together sound muddy, so bass players spread a chord out and leave notes out. Forms with a 3rd or 7th sound clear from about the E string's 8th fret up, so they start there; root and 5th stays low. These forms put the root on the E string; the same shapes work from the A string.
