A quite few people believe that if a person was major in music at music conservatories or university, he must be a specialist in music; have deep knowledge about music, history; have advanced skills of performance or composition, and etc. Of course, this is not the case most of the time.
Let’s imagine a person, a 23 year old newly graduate in economics from a famous university. Do you consider this person as a economist? Probably, no, right? Imagine another person, a 23 year old newly graduate in biology. Do you consider this person as a bio-specialist? Again, no, right? Now, imagine a person, a 23 year old newly graduate in music from a famous music conservatory. Do you still consider this person as a specialist in music? ...Well, no...
As far as the knowledge is concerned, there is not much difference in any major at undergraduate level. So, a music student would know a bit more about music than economics student, and a business student would know a bit more about business than a music student. This is the reality.
The true value of university is in the graduate school. This is where the simple learning ends, and the research starts. You don’t have to be in the school to do research, but the doing research is almost a requirement for being specialist in a certain area.
Consciously or unconsciously, all specialists in any area do research, and ability to do research in a certain area is the difference between a specialist and non-specialist. When you meet a so-called “musician” next time, ask him what he is researching currently. Really good musician will be happy to share his true area of interest with you.
