resource recommendations - What's a good textbook to learn about waves and oscillations?

I'm taking a course on waves and oscillations using Crawford from the Berkeley series (out of print excluding international copies), and would like to know if anyone has any suggestions for a better book.
We cover:

• coupled oscillators,


• forced oscillators,


• Fourier analysis,



• traveling waves,

and some other topics. Any help with the topic would be appreciated.
