Usually, courses of 2 adjacent strings are doubled (tuned to the same pitch).

Unlike microphones, the pickups are not affected by adjacent strings or extraneous noise.

By generally playing three notes per string, consecutive picking across adjacent strings occurs frequently throughout the scale.

A course is a pair or more of adjacent strings tuned to unison or an octave and usually played together as if a single string.

Play this with a lot of attack, and don't worry too much about hitting any adjacent strings accidentally.

They face in opposite directions, plucking the adjacent string on either side of the wider gap.

Since the lyra viol is bowed, all chords must be formed using adjacent strings.

Since all the chords must be formed using adjacent strings, scordatura tunings are the rule rather than the exception.

Usually, courses of 2 adjacent strings are tuned in unison.

Double stopping is when stopped notes are played on two adjacent strings, producing a two-note harmony.
