Whether you are buying an instrument or selling one, you need to make sure you are aware of the price of the instrument. Who better than an appraiser to help you determine the price of the instrument. The pricing of the instrument is hard to determine, and something that requires an understanding of the algorithm.
Here we will discuss the ways in which you can value the instrument and buy/sell one with ease. The two measures that you need to take into account would be the reliability and validity of the instrument. Let’s see how you can measure these two factors- validity and reliability
Validity & Reliability of Instruments
- 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.
- 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
- The criterion validity is somewhat related to the tuning and the scores that are related to the instrument.
- This is slightly different from measuring the validity of the instrument. Let’s dig deeper into what this really means.
- 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
- 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
- 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.
As an appraiser, you need to check for both validity and reliability of the instrument. The time taken to make sure your instrument logs with the standards is real high, which is why most people prefer leaving the instrument with you.
Here’s where the insurance for appraisers plays an important role. In case the instrument that the seller has kept with you gets damaged, you will be made to pay for the same. You can always claim your insurance, and get only half or a quarter percent billed to your account. There are several advantages such as general insurance, medical coverage and even travel insurance covered with the insurance for appraisers.
