Barrees are used throughout the entire guitar world, rock, acoustic
and classical alike and constitute an important part of the classical
guitarist’s technical armoury. There are basically 2 fundamental
types of barree, half or partial and full (leaving aside more complex
areas such as hinge and cross-fret for the time being).
Half Barree
The term half-barree is slightly misleading given that it is used
to denote the coverage of 5 or less strings by the left-hand index
finger for right-handed players, whilst the term full-barree is
reserved for the full coverage of all 6 strings on a standard classical
guitar.
Full Barree
The barree is commonly denote by the letter C followed by the position
at which it is to be laid (i.e. fret number counting from the head
down to the body of the guitar) and the number of strings covered
(sometimes). The letter C is short for cejilla, also commonly called
a capo in flamenco guitar to change down the tuning of the opening
strings without the need to retune all 6 strings of the guitar i.e.
at second fret E on the 1st string becomes f-sharp etc.
The secret to obtaining good barrees is slow, methodical and patient
practise. Many players play with too much tension in the index finger
of the barrees (and similarly in all areas of right-hand technique).
The main objective is to apply just sufficient pressure to ensure
a clean, buzz-free barree is achieved. To do this gently lay the index
finger (say at the 5th or 6th fret-remember just behind the fret not
on it or else this will cause a buzz-effect too) and key gently applying
pressure over all 6 strings until a clear sound is achieved.
Similarly, the thumb should sit comfortably behind the neck of the
guitar, without any pressure being apply in the opposite direction.
It will take some practise and experimentation, not least given the
differing finger shapes and sizes of guitar-players, but is a technique
which must be mastered and one must be comfortable with to play classical
guitar effectively.
A means of practising full barrees, for example, is to play one octave
scales (apoyando and tirando) up and down the fret board, whilst holding
the barree in place. You can do this with half-barrees too.
Slurs
There are 2 types of basic slur, the ascending slur or hammer-on
and the descending slur, or pull-off, often the latter is more troublesome
for many guitarists where tonal consistency is concerned.
Ascending
These can be likened to a quick finger snap, descent onto the string.
Initial starting distance from the string should not be excessive,
around 1-2cm or 0.5-1 inch max.-tone coming from the speed of the
descent and accuracy of the finger on the string (believe me it
is possible to skew from this distance in fast slur passages!) You
should release some of the string pressure immediately after hitting
the string to avoid retaining excess tension in the finger, however
some pressure is obviously required to avoid string buzzing.
Descending
Descending slurs, the troublesome cousin in many guitarist’s
experience, but not insurmountable. Where many guitarists go wrong
is to pull the string upwards, no the string should be pulled down
in the direction to the next adjacent string on the fretboard (obviously
if on the 1st string then not possible but the motion is still basically
the same). This takes some practice to achieve evenness and clarity,
but practice makes perfect. Find out more about scale playing by visiting

There are many combinations of slurs available 2-3-4 notes, hammer
ons onto non-playing strings, but 2 note slurs should be mastered
first as a key basis of your technical armoury.
