The Bach cross illustrates with a single written note, the Bach motif, a short melody consisting of the notes Bb, A, C and B natural, which in German classical musical notation is represented by the letters B, A, C and H which form the surname of the Father of music, Johann Sebastian BACH. Although the musical motif was used before his birth, it is likely to have been in homage to one of his ancestors, who were known for their musical talent. This image was devised in the 19th century to pay homage to Johann Sebastian Bach, and as an additional attraction, it uses the calligraphy of Bach's own hand, taken from the scores he wrote. Because of its age the design is already in the public domain, and does not generate intellectual property rights and we are not aware that it has already been used to create an NFT, so this is surely the first in history, a collector's item that will become very valuable as time goes by.
