What chords are u barring? I got it right through trial
n error. There isn't a standard way to barre as different
ppl's finger isn't the same.
You may try pressing your left index finger directly on the fret
when u r doing a full F chord. You have to decide exactly which
part of the index finger to land on the strings that make minimum
buzzing.
For other chords, u may try to tilt the whole index finger outward
abit, depending whether u can get a good barre n how comfortable it
is to sustain that barre.
Sometimes, it could be due to the poor workmanship of the
guitar.
Best if i can observe on the spot. then I can pinpoint the
problem.
