picking pattern when playing scales?
So I've always wondered whether there is some agreed method of how to efficiently pick scales moving from string to string, or if it's all a matter of preference.
When ascending for example a simple Am pentatonic would you (assuming I'm moving down the strings from 6th to 1st):
DU, DU, DU, DU, DU, DU; or instead: UD, UD, UD, UD, UD, UD (I feel this movement could be more economical in the sense that on the down stroke your hand is moving in the direction of the string below it, but I know this can also affect the sound by means of your attack, correct?).
Refering to the previous scale would a decending pattern just be(going from the 1st string to 6th):
UD, UD, UD, UD, UD, UD? or DU, DU, DU, DU, DU, DU?
& When ascending three note per string scales, for example a G Maj, would one:
DUD, DUD, DUD, DUD, DUD, DUD; or DUD, UDU, DUD, UDU, DUD, UDU (is the first pattern just economy picking and the second alt.? )
These might be no brainers, but I'm really trying to get a set method of practicing my picking movement down and some clarity in this area would help immensely.
