This title builds on introductory physics and emphasises understanding of vibratory motion and waves based on first principles. It is divided into three parts: Part I contains a preliminary chapter that reviews relevant ideas of mechanics and complex numbers; Part II discusses vibrations of mechanical systems, covering a simple harmonic oscillator, coupled oscillators, normal coordinates, beaded string, continuous string, standing waves, and Fourier series. Part II ends with a presentation of stationary solutions of driven finite systems. Part III is concerned with waves
