Slate writer Jan Swafford writes very fascinating articles. There's a list of them here: http://www.slate.com/?id=3944&qp=40341

Her two most recent are a delight. One talks about the history of tuning, and why certain composers used certain tunings and keys to evoke moods: http://www.slate.com/id/2250793/

Another talks about the homogenization of modern pianos, and how we loose some of the composer's original intent in our modern actions: http://www.slate.com/id/2245891/

Make sure you have speakers or headphones, because she has side-by-side audio comparisons.
