Emily needs a change of scenery. She's been pegged as the "arty girl" by the kids in school - even her own friends. There's some truth to that, but there's more to how she sees the world than painting or drawing, and no one seems to understand that.So when Emily gets the chance to go to an art program in Philadelphia for the summer, she jumps at it. A new cast of characters enters her life... and suddenly she has to figure out who she wants to be. She's gone from the suburbs where everyone's trying to be the same to a school where everyone's trying to be unique. The rules may have changed, but the pressures haven't.With wit and empathy, Siobhan Vivian goes straight to the heart of a teen girl's search for identity - including the pain and heartache we have to go through to figure out who we are.

This book addresses the analysis of musical sounds from the viewpoint of someone at the intersection between physicists, engineers, piano technicians, and musicians. The study is structured into three parts. The reader is introduced to a variety of waves and a variety of ways of presenting, visualizing, and analyzing them in the first part. A tutorial on the tools used throughout the book accompanies this introduction. The mathematics behind the tools is left to the appendices. Part Two provides a graphical survey of the classical areas of acoustics that pertain to musical instruments: vibrating strings, bars, membranes, and plates. Part Three is devoted almost exclusively to the piano. Several two- and three-dimensional graphical tools are introduced to study various characteristics of pianos: individual notes and interactions among them, the missing fundamental, inharmonicity, tuning visualization, the different distribution of harmonic power for the various zones of the piano keyboard, and potential uses for quality control. These techniques are also briefly applied to other musical instruments studied in earlier parts of the book. For physicists and engineers there are appendices to cover the mathematics lurking beneath the numerous graphs and a brief introduction to Matlab® which was used to generate these graphs. A website accompanying the book (https://sites.google.com/site/analysisofsoundsandvibrations/) contains: - Matlab® scripts - mp3 files of sounds - references to YouTube videos - and up-to-date results of recent studies
