Thought I'd practice a bit on my ear training, so I plugged my iPad into my practice amp and fired up Pandora then selected some bizarre music channels where I wouldn't know any of the songs at all. The goal is to figure out the bassline before the song is over. Kinda fun and different and very challenging.
Avoiding the traditional rock and roll music I normally play has been an eye opener. Tango, Polka, Mexican Folk, Classical Piano, French Lounge Jazz, Russian Ballet, New Age Cool Jazz and Trip Hop are a few of the different types of music I've tried. Can't say I'm great at it or that I get it all correct but its surprising how much of it I am able to accurately play along with. Just something different and fun.
