Being also a bass player, my opinion of the Pachebel Canon (which is in D, by the way) can be summed up by the following video on YouTubehttp://www.youtube.com/watch?v=JdxkVQy7QLM
I am a little baffled by the thought that someone, even if only 18, would take a bass line from one piece and a melody from another and call it composition. Maybe in this post-modern world of sampling, file sharing, clip art, and other forms of digital instant gratification, it becomes the case that one person's creativity is everybody's creativity. I must sound hopelessly archaic when I say that I believe that composition is when someone writes his or her own music. Even in cases where composers are quoting other music, or, as in Berio's Sinfonia
for example, where he is constructing a collage, there is a meaningful purpose for doing so. Another example is Saint Saens' Carnival of the Animals
, where he quotes to be funny. These composers, however, are being deliberately exceptional, and certainly can and do write music on their own. Even if you are writing music in a Baroque style, you will derive more benefit from writing your own music than by copying and recycling the music of others. But even if you do, for the sanity of all bass players, please use something other than Pachebel's Canon!
Despite all of the aforementioned feigned alarm, if you are drawn to writing your own music, by all means follow your urge with a passion. It is one of the more gratifying activities you can pursue!
Best of luck,
