Fair use for Timpani

This audio clip, Bartók - Sonata for two pianos and percussion - Assai lento - Allegro molto (clip).ogg, is being linked here; though the recording is subject to copyright I (– flamurai (t)) feel it is covered by the U.S. fair use laws because:

1. it is an excerpt of a longer work;
2. it is used to illustrate the sound of the instruments;
3. it is used to illustrate a concept specifically mentioned in the text (the timpani glissando);
4. a free recording of high enough fidelity and performance quality to appropriately illustrate the sound of the instruments in this work could not be found.

Fair use rationale for Sonata for two pianos and percussion and Béla Bartók

I believe this file is fair use in the article Sonata for two pianos and percussion because it demonstrates the sound of the work, it cannot be sold commercially to violate the original copyrights, and it cannot be replaced with a free version. The same is true for its use in Béla Bartók. Graham87 02:07, 11 March 2008 (UTC)
