(1)_____________________________________________________.We have covered several centuries in a very short time.Much too short to do the music justice, of course,but then this year is the survey course.From now until the end of the term,we’ll be talking about and listening to electronic music.You probably already know that it was in the 1950’s that musical computers and synthesizers first appeared in university.The first commercial synthesizers were sold about this time, too.(2)_________________________________________________.Some alarmists believe these new instruments will bring an end to classical music or they already have.You know I don’t share this view,but I do agree we are in the midst of a revolution in instrument design.This, however, is not the first such revolution in musical history and probably not the last one either.Remember we’ve already studied a similar case in the early nineteenth century when the piano replaced the harpsichord and modern brass and wind instruments came into being.One of the most important reasons for the great popularity of electronic instruments is of course their relatively cheap price.Well, just look at it.Only about 400 dollars for an electronic keyboard compared to nearly 3 000 dollars for a piano.Naturally, this has done a lot to increase sales of electronic instruments.(3)______________________________________.
We are rapidly near the end of this course in the history of classical music.
This synthesication in compasity have now increased to point thay can do almost any kinds of sounds.
But I do not think even the most artists supportors of the electronic intrument expect them completely place akustic intrument.
