My knowledge of the Berklee College of Music is limited to a daughter who took a summer course there, plus two former guitar teachers who had studied there (I was the student of one, both my daughter and I were students of the other).
Yes. My daughter did learn quite a bit from her summer course at Berklee, and liked it quite a bit. Some of what she learned involved music and songwriting, but some did also include business aspects related to having a career in music (plus a bit of copyright law). I do not think that we spent $20k for the summer course (I do not think that we would have been willing to spend this much, and she did not have anything close to this at the time). After this she had a musical tour of Europe, decided that she got tired of the music and did not like travel, and switched to a different potential career (she is currently studying something very different). I think that the summer course might have helped if she had decided to stay with music, but I do not think that it ended up mattering given the path that she has taken.
Of the two guitar teachers, one ran out of money before getting his bachelor’s degree and found that he was not qualified to borrow enough to complete his degree. He had to drop out of Berklee and then transfer to an in-state public university. He ended up with a degree from his in-state public university, plus debt from his study at Berklee. He would have been better off starting at his public university in the first place. He had to give a lot of guitar lessons to pay off his college debt.
The other was getting a master’s degree at Berklee. He was a very, very good guitar player, a very good teacher, and a nice person. He seemed to be able to afford it, but I have no idea how and never discussed this with him. I am guessing that the guitar lessons that we took from him had something to do with how he was able to afford to attend Berklee, but I have no idea whether a scholarship or family money also helped. He also seemed to enjoy his studies at Berklee, and was good at a wide range of types of music. He specifically taught me both electric guitar and classical guitar (as a result of this the day that Les Paul died I played “Lágrima” (tears) on my electric guitar in his memory, but that is another issue).
