As the business of art (and in my case music) progresses into the twenty-first century, technology continues to have an impact. That's not so unusual. Two hundred years ago a song was deemed a hit if it sold multiple copies of sheet music. Then it was determined by how many records were sold. Now it's more likely to be determined by the number of streams it has.
It the world of painting and drawing, multiple copies can be made and sold. I have artist friends who will reproduce larger works in various sizes or even as greeting cards. A sculptor has the ability to do similar things. Although this has been the case for a very long time, todays technology makes it easier and more affordable for the artist.
The printed word is now very inexpensive to reproduce and publish. In both literature and music, publishing on-demand is taking over the old paradigm. I've written a couple of exercises for my students and have them available on my website. The students (or anyone else) can simply go there and download them for free. Some will print them and others will just read them from their tablet.
Other things that I can do include giving online lessons, emailing printed music and recordings of me playing a demo of the lesson. Some lessons can be pre-recorded and made available as needed. For my advanced students I can reference YouTube videos for them to watch.
Because I play at weddings, I can offer samples and demos of me playing some of their favorite wedding songs. I also will send a recording of me playing their wedding processional for the bride and groom to include in their wedding album. Such things would have been prohibitively expensive just a few years ago.
I like the opportunities that the ever-changing technology affords me and I'm always on the look out for new things to do with it. But I need to weigh each new thing and determine if this is going to work for me or if I'm attracted to it because it's shiny and new. I must be careful to remember that the technology is simply a tool. The value in the tool lies in what I can build with it.
