You want to write about the development of electronic music.

We can develop from classical music to modern music and then to electronic music.

Then, on the basis of the event, talk about your experience about the change of music from ancient times to electricity. Do you think it is progress or retrogression?

Then say, why do you think it is retrogression (or progress)? If you have another view, such as progress on one hand and retrogression on the other, you can also describe it clearly.

It is best to sum up and say whether the development of electronic music is a trend or a retrogression, and so on.

I don't know about you, so I can't write for you. ...

Can only say my opinion!
