Here is a Carlos Santana lick from the first solo (not the intro) in the song "Black Magic Woman". It is in the key of D minor, and comes completely out of a D natural minor scale.

The red number is the note that you should use as your guide when playing the lick in other keys. In this case the red note is a D. This lick is in the key of D minor. If you wanted to play this lick in B minor, then you would move everything down 3 frets so that the note in red would be at the 7th fret (B).

Here is the fingering for the D minor scale that this lick is played out of.

The notes in red are the D notes (the root of the scale).

The lick starts out with an Fmaj7 arpeggio, which is a chord that can be build from the D minor scale. Playing arpeggios within a particular scale is a great way get out of the rut of just playing up and down the scale.
