It was Sunday evening, but the clock said two a.m., Monday morning. He was awake in an instant. Someone was trying to kick his door in. Adrenalin started to flow. Grabbing his squash racquet, he strode to the door, turned the lock as quietly as he could, then snatched the door bolt open quickly. The sight that met him was terrible. Tom stood in front of him, soaking wet, covered in mud, with red eyes and a look of terror. Ewan pulled him in, checked that the corridor was empty, closed the door and slid the bolt across.Dripping puddles on the floor, Tom looked as if ghosts had chased him. He was shaking all over, and his stammer prevented any recognisable words. Then this normally bluff Yorkshireman collapsed into Ewan's arms. The hug was wet and cold. Tom was sobbing. Something was seriously wrong.

This book provides an in-depth account of the fascinating but far from simple actions and processes that take place when a brass instrument is played. Written by three leading researchers in brass instrument acoustics who are also experienced brass players, it draws together the many recent advances in our understanding of the subtly interrelated factors shaping the musician''s control of the instrument''s sound. The reader is introduced to models of sound generation, propagation and radiation. In particular, the current understanding of the behaviour of the player''s lips, the modes of vibration of the air column inside the instrument, and the radiation of sound from a brass instrument bell are explained. The functions of the mouthpiece and of mutes are discussed. Spectral enrichment arising from nonlinear propagation of the internal sound wave in loud playing is shown to be an important influence on the timbre of many types of brass instrument. The characteristics of brass instruments in contemporary use (including cornets, trumpets, french horns, trombones and tubas) are identified, and related to those of the great variety of instruments at earlier stages in the evolution of the brass family. This copiously illustrated book concludes with case studies of the recreation of ancient instruments and some of the current applications of electronics and information technology to brass instrument performance. While most of the material presented is accessible by a general readership, the topic of musical instrument modelling is developed at a mathematical level which makes it a useful academic resource for advanced teaching and research. Written by three internationally acknowledged experts in the acoustics and organology of brass instruments who are also experienced brass instrument players. Provides both an accessible introduction to brass instrument science and a review of recent research results and mathematical modeling techniques Represents the first monograph on the science underlying the design and performance of musical instruments of the brass family

Fraser, a Scottish teenager, follows his best friend to Canada, only to discover their friendship didn't survive the journey. Alone, in more senses than one, he faces a clique at his new school which is hell-bent on making his life a misery. He is warned off doing well in class, and an impending public recital competition puts him in the firing line. He cannot hide from their unwelcome attention. As an escape, Fraser sets off on a camping trip and has a curious, fortune-changing encounter. Helping hands embolden him to plot a route to even the odds; however, there are cow-pats on the road ahead. His idea offers payback but needs his peer group to get their noses in the trough first. Would they act true to form? Would his guardian angel or St Christopher medallion protect him on this perilous venture? Either way, the very thought made him chuckle.

Presents a comprehensive survey to explain how Western musical instruments work, how they developed historically, how they are manufactured, and how they are used to make music. This book introduces the nature of sounds in music, and tells about the sound production mechanisms of different families of instruments and the distinguishing features.
