I play guitar but I don't even know what you mean by descending E and ascending A and the pentatonic. I'm a "play along with the record" kinda guy. That way, no matter how bad I am, the band tends to bring me up. ;-D
Major Scales
=========
Much of Western music is written in the Major Scale. There are seven tones to a scale, you know them as "do, re, mi...". Any note can be a starting point of the "do, re, mi.. etc." It is knowing where the next notes are depends on where you start the root or "tonic" note. If you start on the "E" string ascending (going up: do, re mi,...), there is a certain pattern. If you start on the "E" string decending (going down: do, ti, la,...) there is a certain pattern, etc.
Petatonic (5 Tone) Scales
==================
Pentatonics are very cool, and you need to learn them if you want to screw around with leads. Any song is written in a what is called a "Key Signature", for example, a song written in the Key of C. Within that key, the chords that may be used and that sound good together are C, F, G (or G7), B7, Am, etc. Pentatonic (5 tone) scale will work across the full set of chords of the Key signature, so you can improvise effortlessly. There are 5 shapes of the five tones (I think: - I'm a rookie learning on my own). So, for example, Up and down the fretboard you can utilize the C pentatonic in 5 different spots in a 14 fret span, using the five different shapes.
Of course, it could all be bullshit, but I think I wrote it right.
