Abstract
An electronic musical apparatus is designed for using original music contents kept under protection. In the apparatus, an editing section is operable to edit an original music content into a variational music content. A content judging section compares the variational music content with the original music content and judges a degree of difference therebetween to provide a judgment. A transfer control section operates based on the judgment for permitting transfer of the variational music content to an external apparatus beyond the protection. The content judging section operates when a degree of difference is sufficient to remove the protection for providing a positive judgment and operates when a degree of difference is insufficient to remove the protection for providing a negative judgment, and responds to the positive judgment for permitting transfer of the variational music content beyond the protection and responds to the negative judgment for inhibiting transfer of the variational music content within the protection.
