Although many people aren't aware of this, the fingerboard also vibrates with the instrument. This may or may not contribute to the overall sound characteristics. However, by tuning a fingerboard to a specific frequency that matches/couples with one of the primary body frequencies, it is possible to greatly enhance the "feedback" that the musician receives from the instrument.

The images shown span from the top of the scroll to the end of the fingerboard. So, in the images, at approximately 1/4 the length you will see a small black line which denotes the beginning of the fingergboard and with that in mind, it's fairly easy to estimate the point at which the fingerboard leaves the neck and extends over the belly of the instrument.

These animations also help us to understand why an instrument may feel quite different after having the fingerboard dressed.

The role of the tailpiece is often underestimated and yet, it too is vibrating and either enhancing or detracting from the musician's experience. The following animations show the tailpiece vibrating at various frequencies.

The black line seen on the screen denotes the location of the tailpiece saddle. Changing the tailpiece will obviously change the vibrational feel of an instrument.
