"Before playing the following tremolo exercises,
consider your overall technique. I often observe
students wishing to have blazing fast and even
sounding tremolo while their scales and arpeggios
have not been fully studied. How can we play tremolo
if our i-m, m-a, and a-m-i scales are lacking control?
How can we play tremolo if simple arpeggios have not
been brought up to speed? As with any technique, a
fast and even tremolo is reliant on accuracy, control,
relaxation, and a well-rounded technique overall. In all
fairness, a student who can play their scales and
arpeggios well (with all finger combinations) will be able
to play tremolo with ease. That said, tremolo is a
specific type of right hand technique so practicing
these exercises should help organize your right hand."

"Guitar is not a sustained instrument. In plain English,
the note dies out very quickly once it comes out. Piano
is the same. Then there are sustained instruments
such as violin or flute. These instruments can truly play
long notes as written on the scores. But a guitar
cannot create a sustained note (unless you have an
electric guitar with a pedal). So, probably a smart
player at some point thought he or she could use the
fingers repeatedly to create a mandolin-like effect while
plucking accompaniment notes with the thumb.
Therefore, tremolo is an attempt to mimic a sustained
instrument or a singer using a guitar.
In classical guitar, tremolo is typically played P a m i,
which is one bass note followed by three trebles - 4
notes in total. The flamenco tremolo is made up of 5
notes: P i a m i. The key to developing a nice and
even tremolo is to basically do the opposite of what
you do for fast picado. Speed burst, which is extremely
useful for picado speed, is detrimental to
homogeneous tremolo. In complete opposition to the
"twitch" approach of picado, you have to consider
each and every tremolo note as a separate entity that
is governed by a beat (or a fraction of a beat) on the
metronome. Tremolo has to be practised very slowly,
giving each note equal value." in www.atrafana.com
