Appraisers are an
important part of the music chain, along with recording studios, instrument
sellers and even musicians. The appraisers are the ones you will contact when
you are in desperate need to get your instrument replaced. They are the ones
who will tell you the worth of your instrument, and what is the maximum amount
you might get from selling it. They understand the instrument; have the right
tools and techniques to measure the instrument’s value in the current market.
If you are an
appraiser or, want to be an appraiser, the two terms that actually connect with
you are validity and reliability. From the end user’s point of view, these are
mere terms that you use to value the instrument. Here we will talk about how
appraisers actually measure the value and why there is a need for insurance
for appraisers.
What do validity and reliability of the instruments
imply?
Validity is the
degree to which an instrument aptly plays or sounds like it is supposed to be.
Here we will see how to measure the validity of the tones, the sounds and even
the bass of the instrument.
o
The
content validity is the first measure, which represents how adequately &
accurately the instrument plays the sound. You will obviously need to see if it
can be toned and tuned to match the needs. You can always check with the
subject matter expert in case you have your doubts
o
The
criterion validity is somewhat related to the tuning and the scores that are
related to the instrument.
Reliability is
slightly different from measuring the validity of the instrument. Let’s dig
deeper into what this really means.
o
There
is a scale to which every music instrument is measured. There are standards
that these instruments need to adhere to. This is where you will need to check
for internal consistency reliability of your music instrument. You will need to
check if every aspect of the instrument meets the standard scale determined by
some institute. There is the difficulty level of the instrument, size etc. that
comes into question at this point
o
You
need to check for consistency within the different scores determined for the
same instrument. This includes taking up several tests for the same instrument,
and determining if the results are consistent. If there is too much of
variation, the instrument probably requires a check and is not too reliable
o
Finally,
the tuning and toning of the instrument needs to be reliable. It should not
take too much of effort to tune, and when tuned, it should not affect the
instrument’s capability in any way. The reliability in terms of tuning is very
important from selling perspective.
When you interact
with an appraiser, you will notice that they check the combination of the two
before mentioning the actual value of the instrument. This entire process takes
a considerable amount of time, which is why most people leave the instruments
with the appraisers.
As the appraiser
has to handle these instruments at the store, it is important that they invest
in the insurance for appraisers. It will protect their store, the instruments
people leave behind as well as their best interests.
