MAKE has published a cool new book, called Make: Analog Synthesizers by Ray Wilson. It's a deep dive into DIY synthesized music, with lots of circuits and information on using electronic components, but it has plenty of introductory material so it's suitable for electronics novices. I admire the author's design aesthetic too -- the devices he shows you how to build look neat.
