Ascending and descending

Question: "In "Guitar Playing and how it Works" where you say "Placement of the LH fingers ascending" and "Placement of the LH fingers descending", in which dimension "ascending" and "descending" are you referring ? Is it touching and releasing the strings?" - Paulo, Sept, 2006
Answer: By "ascending" I mean ASCENDING the scale, going UP in pitch. By "descending" I mean descending the scale, going down in pitch.

We always use general musical conventions where possible. Every instrumentalist can play an ascending scale, each instrument will have a different set of movements required to do that.
