Hello,
I understand that when someone says "A cello tuning is a 5th apart" means that the strings are a tuned a 5th apart. However, I'm trying to wrap my mind around what this means when applied to composition. I am not a string player and was looking for some direction on this as the cello can obviously play each note in their range. (This would be the same for any stringed instrument.)
Any resource would be great too.
