In questions and answers on this site, I see a great deal of confusion about directions.
I've seen "lower string" refer to strings that are lower in pitch, and to strings that are closer to the floor (therefore, opposites on a conventionally tuned guitar).
I've seen "up" mean:
- away from the fretboard
- towards the nut
- towards the bridge
... so two different directions on the same axis, and a third perpendicular to that.
... and "down" having the complementary three meanings.
In one conversation I saw
Do you mean you are pulling "down" towards the edge of the fretboard or "up" and away from the fretboard?
... where "up" and "down" are not even opposite directions to each other.
Is there a commonly agreed set of meanings for directions; if not, what can be done to communicate our meaning more clearly when talking about fretted instruments?
