It is very
important to keep your piano in tune. Recommended tuning for
most pianos is having them tuned every 6 months.
Here are a
few specialty tools I normally use when tuning a piano.

When tuning,
to save time, I also use a lap-top with an electronic tuning
device - but fine tuning is always done by ear because I have
found that my ear is more sensitive to higher pitches.
There are many
different forms of playing a piano. You may be a concert pianist
or just play for your local church. Some of you may be new students.

From the layman's standpoint, two tunings a year should be
sufficient. ..."
