Yes...but the 8KHz that cuts off is one octave...and is probably not the fundamental tone of any musical instrument. If it is present, it adds to the sound of things like cymbals (and possibly stringed instruments?). It would be interesting to use sharp high-pass filtering to cut out everything below 8KHz and see/hear what remained...
