I took piano lessons for about 4 1/2 years, and after a 4 year hiatus, I've recently found myself getting back into piano. Right now I'm just working through some simple tunes to help me get my techinique and sight reading back, but I'm enjoying it more than ever. The reason I'm posting this though is by going back and playing piano, it's totally reshaping how I look at the the relationship between harmony and melody. Since a piano is both a harmonic and melodic instrument, it really makes it easy to see exactly what's going on in a piece of music. Counterpoint seems to be making a lot more sense. While I really have no desire to play piano in a group context (that's what I play bass for) it's really helping to fill in a lot of the gaps with harmony and melody. Even simple tunes out of the John Thompson student books have a lot to offer in terms of actual musicality.
