To speak of the pipe organ is to speak of Bach, and it undoubtedly owes much of its development and importance to Bach's dedication to it as a means of moving the souls of the faithful. This piece, the little prelude and fugue in D minor, is the first organ piece by the father of music to be made into a NFT, so it will soon form part of the collection of a true connoisseur of the classical art. In addition, this NFT contains the only copy of the performance of the work. The file will be destroyed after mining, to make this NFT an absolutely unique piece.
