The first music technology I feel is most applicable is the art of producing music, specifically in the recording aspect. A performer has to be able to record themselves for multiple reasons. The most important, in my opinion, is to produce a CD that may get them a job. Since I am going into performing, recording and editing my own CD's will be very important in the future.
Music notation is definitely on the list of the top 3 music technologies. As a performer, it is important to know how to read music (obviously) and interpret music. But to fully understand why certain songs sound the way they do, a musician should know how to write music and create their own songs. Without that knowledge, musicians can only get so far.
The final music technology I feel is most applicable is networking and communicating with other people. If you keep to yourself, you will get nowhere in life. It is important to establish connections, to put your music out there in the world. But in order to do that, you need to know how. This is an important part of becoming a full-time musician, and should be considered a very important part of music technology.
