There’s a good chance, that if you’ve been involved in music much for the last few years, you’ve probably gotten some sort of catalog from Disc Makers. I know I’ve gotten a ton of them, and they’re always fun to look at. While they do want to sell you on their services, the also do a lot of helpful things for us musicians. One of those things is the writing and collecting of good articles for musicians and for recording. I came across some of those articles today.
These are a couple of links to some ear training articles they have posted on their blog, Echoes. These articles were actually written by Evan Kepner who runs No Treble, which is a cool site for bass players.
