Metal is a lot different today than it was in the ’80s. Back then, things were brutal. If you didn’t know how to solo, you weren’t even looked upon as a
Many guitarists can play an A minor pentatonic scale, but how many really know all five pentatonic “boxes”? They’re presented in Ex. 1, with every appearance of the root, A, circled. Box 1—by far the most popular of the bunch—starts at the 5th fret, and each new box starts one scale tone higher up the neck. Once you’ve learned all five patterns, I suggest putting yourself through my Pentatonic Workout, which goes like this: Ascend through Box 1, then descend through Box 2, then ascend through Box 3, and so on. Once you’ve gone through all five boxes, do the whole process in reverse going down the neck. (Remember that you can also play Box 5 an octave lower in the second position.)
The next step is adding variations to the Workout. For instance, instead of only using alternating picking, try playing the scales legato, where each picked note is followed by a hammer-on (ascending) or a pull-off (descending). Then, employ different pitch sequences, such as the rising six-note triplet pattern in Ex. 2 (which you should also practice descending) and the “ascending while descending” approach in Ex. 3, moving each new pattern through all five boxes. The whole point of the Workout is to develop fretboard visualization, because the most important thing when improvising is being able to see the entire neck as a whole. The more you practice these five boxes, the more they will begin to merge into one giant box.
