Do modern performers have the freedom to interpret music from the past in ways that the music original music composer had not intended? May we use modern instruments?

The correct answer to this open question is the following.

Although there are no options provided or further context, we can comment on the following.

Yes, I consider that modern performers have the freedom to interpret music from the past. The only thing is that these modern performers do it with respect and comply with all the legal requirements of intellectual property, artists' royalties, and author's authorization to perform the songs.

Of course, modern interpreters would like to add their own personal touch or distinctive sound to past songs, and that is ok. Indeed, it is expected. Nobody wants to listen to the same song because that is why an original one already exists.

Modern instruments can be sued to perform songs from the past. It is more than welcome to have new styles, different instruments, that could improve the song or at least, that can be accepted by new audiences.
