Our technology is revolving and so are other things. Before we used books to read but now you can read thru e-books in your ipads, tabs or phones. Shopping was only done in malls or stores but now you can shop online. And same with music, I used to buy song hits before to check on new music but everything can be found thru the internet. And how most musicians are more than glad because there it's either they can teach or learn music with technology. You can try checking gia publications at wwbw where you get to learn more about music and its instruments.
