Imperfect Harmony: Finding Happiness Singing with Others by Stacy Horn (An exploration of the physical and emotional wonders of choral singing.)
A Romance on Three Legs: Glenn Gould's Obsessive Quest for the Perfect Piano by Katie Hafner (As a pianist myself, I found this book absolutely fascinating. Who knew you could tweak the sound of a piano in so many different ways? My review.)
Strings Attached: One Tough Teacher and the Gift of Great Expectations by Joanne Lipman & Melanie Kupchynsky (We've all had teachers who inspire us. When it's a music teacher, so much the better!)
The Cello Suites by Eric Siblin (This was a five-star read for me. It tells the story of Bach's Cello Suites, the Spanish cellist who rediscovered them, and Siblin's own journey to learn how to play the cello. My review.)
Beethoven Remembered by Franz Wegeler and Ferdinand Ries (A book about Beethoven, written by two of his good friends. A music history lover's paradise!)
The Ninth: Beethoven and the World in 1824 by Harvey Sachs (Beethoven's most famous symphony - the one with Ode to Joy - put into its historical context.)
Bach, Beethoven, and the Boys: Music History as it Ought to be Taught by David W. Barber (For those who like a little humor with their history.)
The Definitive Biography of P.D.Q. Bach by Peter Schickele (P.D.Q. Bach is the little-known 21st of Johann Sebastian Bach's 20 children. In other words, he's completely made up. And completely rolling-on-the-floor hilarious. Any music lover has to read this book!)
