new strings. Intonation problems are often the
result of worn strings. It is often difficult for the
untrained ear to determine when the open note and the fret-
ted note are at precisely the same pitch. Some players find
that comparing the 12th fret harmonic of the string (rather
than the open note) to the fretted note is much easier. A har-
monic is played by plucking the string with the right hand
while touching the string with the left index finger (as lightly
as possible) directly above the 12th fret. The left index finger
is drawn away as quickly as possible after the string is
plucked‚ producing a "chime" effect. This chimed note is
then compared to the fretted note. For greater ease and accu-
racy‚ we recommend one of the many types of electronic gui-
tar tuners that are available from most music stores.
