There are two distinctive types of classical guitar technique.
General and Specific.
The dictionary defines general and specific this way : Gen-er-al \ 'jen-(e)rel\ adj.
: not confined by specialization or careful limitation Spe-cif-ic \ spi-'sif-ik\ adj.
: restricted to a particular situation or effect free from ambiguity General technique is only slightly enhanced by the physical act of playing "Pieces of Music".
I'll repeat this because it bears repeating.
General technique is only slightly enhanced by the physical act of playing "Pieces of Music".
The discussion of open or closed right hand position, for instance, is a discussion revolving around general technique and the circumstances around interpretation of pieces of music.
It is the overall skill level, "in general" as in, can one easily play sixteenth notes at MM 80 or is it a struggle at MM 120.
"Specific" Technique is what I refer to as the skills required to play a given "passage" in a particular piece of music.
Every piece has one.
A measure or two, perhaps a long passage that presents unique, never to be seen again, challenges to ones "general" technical skills.
Be very careful to keep the two pursuits separate.
One student played the Giuliani Arpeggios endlessly, developed dystonia, and then couldn't play for several years.
He was hoping that they would skyrocket his General Technique.
They didn't! The Giuliani Arpeggios, contrary to popular belief, are "Specific " exercises and only slightly improve ones "General" technique.
In fact, I found that only a few of them have real merit, and as it turns out, they only have merit to the extent that they only improve the "Specific" techniques required to play Giuliani's own Guitar Compositions! Surprise, Surprise! So, if you want to play some of Guiliani's Warhorse pieces that Bream recorded so brilliantly, practice the Giuliani Arpeggios.
One should use them not as Right Hand Exercises but rather as Left Hand Exercises.
If you know them, you're thinking, Left Hand ? Why, they are just a simple stationary "C" chord that the Right Hand then arpeggiates across the strings.
I think Giuliani missed his own boat when he wrote them as Right Hand Exercises.
To Your Music and To Your Success!
