So everyone knows you have to practice inorder to be good with your instrument. Since this is going to be very important next campaign, here below is the chart describing how long you have to not practice an instrument in order for your skill score to drop, assuming no magical interference (note: since no one is playing a music-based race, none of you get any natural bonuses to stave off depreciation).

Those with experience with musical instruments, tell me if this seems reasonable

To go from a 22 to a 1 takes a little over 11 years. I know it ain't perfect, so critique this so we can get it to some semblance of reality.

Newly gained skill depreciates differently.
